Step by step process of how to check your dipstick and monitor the engine oil in your car to keep the oil level optimal and your engine running pristine! As shown in Figure 6, the values obtained from the data are much lower, with R² at 0.05 for SAE 0W-20 and 0.17 for SAE 5W-30 engine oils. In cold-room dynamometer tests, it was determined that there were two forms of the pumpability problem. Even so, to help control warranty costs, the development and use of engine tests is unavoidable for engine manufacturers when determining the oil quality needed for a particular design or component. The process is easy and uncomplicated. —A Q&A with Kimberly Eros, Henny Penny Project Manager, Insights. The parameter was called the gelation index. In the first analyses of volatiles collected from the bench test, it was apparent that the phosphorus additives in the engine oils were also producing phosphorus through additive decomposition. Why do frying oils need to be tested at all? These grade requirements are also shown in Figure 2 for comparison. Most people overlook checking engine oil. Without question, the quality of engine oils will play a much greater role in the smaller, more powerful turbocharged engines that are entering the automotive market. Unfortunately, for the uninformed automobile owner, a high-quality engine oil and one of poor quality will look and feel the same. The FFA strips are easy to use and don’t add any interruptions to frying time. They can be purchased for around $30. Not all vehicles take 5 quarts of engine oil. Your email address will not be published. Start by consulting your owner's manual. As expected, it was determined that the yearly averaged multigrade SAE 0W-20 oils contributed more fuel efficiency to the engine than did the averaged multigrade SAE 5W-30 oils because of the viscosity differences shown in Figure 2. The engine oil quality is critical for the life of the engine. Unburned or partially burned hydrocarbons from the engine exhaust were modified by sunlight into noxious gaseous hydrocarbons, which produced smog in some large cities. A lubricant’s viscosity has always been associated with wear protection. This same molecular friction prevents the oil from escaping too quickly when two engine surfaces in relative motion are brought closely together under pressure. The lack of correlation between the phosphorus in the engine oil and the amount of phosphorus volatilized is evident in the low correlation coefficient (R²) values. If the engine oil level is above the High/Max mark, you should remove oil from the engine to avoid damage to your car. How much influence the phosphorus in an engine oil has on the amount of phosphorus volatilized during engine operation is an important question affecting the choice of additives in oil formulation. Apart from checking the smell of the diesel engine oil, you can also smell your petrol engine oil. Here's some info on the sensor. However, using the engine to measure oil quality in dynamometer tests can be an expensive proposition. Since that time, multigrade oils (e.g., SAE 10W-40, 5W-30, 0W-20, etc.) TPM Measurement: These devices determine the quality of cooking oils by measuring the total polar materials (TPM), or non-triglycerides, based on changes in the dielectric constant, which is measured between two capacitive plates. Engine Oil, Check! During the oil’s service, the engine generates a number of operating stresses that adversely affect the long-term ability of the oil to function at a consistently high level. Today, the grades are set for engine operating temperatures and for winter temperatures at which the oil affects starting and pumping. This information was used to develop the viscous fuel efficiency index (V-FEI) parameter. Check the quality of the oil as well by rubbing it between your fingers. Name *. It is evident that considerable progress has been made in reducing the phosphorus decomposition and/or volatility of these two multigrade SAE classifications. However, interest among US operators to monitor oil quality is on the rise as operators want to ensure they’re providing a quality experience to their guests. The bottom line is that it can translate into less engine wear, improve your fuel economy, and prolong engine life. Fried food quality is a function of oil quality. This determination can only be made by using the oil or pre-testing it. To do this, simply dip your dipstick and sniff it. Density ranges from light to heavy, while sulfur content is characterized as sweet or sour. There are several different methods used to measure oil quality ranging from subjective visual inspection to more objective, scientific measurements. The technique was accepted by ASTM as test method D4683 for use at 150 degrees C (and more recently as D6616 for use at 100 degrees C). To check the oil level park the car on a level ground. Metal shavings from engine parts, foreign debris, and oil that doesn't lubricate properly can all contribute to eating up an engine. Two of the most important quality characteristics are density and sulfur content. This article will show you how to check your engine oil consumption properly. I had to take it back to the basics for those who don't know much about cars. It collected the volatile component of the volatility test for further analysis, which was helpful in detecting phosphorus and sulfur. How to check motor oil level. The oil drain intervals, to be effective, must be determined by oil analysis. Even as engine design has changed to meet performance, fuel efficiency and environmental standards, the engine continues to be the ultimate arbiter of oil quality. These grades are defined by viscosity levels in one or two temperature zones. Consequently, the need arose to develop a high shear rate viscometer to reflect the viscosity in engines under operating temperatures. But if it has a light, milky appearance, this could mean coolant is leaking into the engine. On the basis of these findings, a parameter related to the amount of phosphorus released during the test was developed called the phosphorus emission index (PEI). According to a recent study by ExxonMobil, a shocking 50 percent of drivers in the U.K. don’t know why engine oil is needed, while 75 percent don’t know HOW to check their oil. Read More » HEAVY DUTY DIESEL ENGINE OIL PETROLEUM QUALITY INSTITUTE OF AMERICA SAMPLE SUMMARY/HEAVY DUTY DIESEL ENGINE OIL Heavy duty diesel engine oils are formulated to meet … First, check the owner's manual and follow the automaker's recommendations. Once you have allowed the engine to run for a couple of minutes, allowing the oil to circulate, turn off the engine and allow it to cool for about 5 minutes or so. See how easy it is to test your own engine oil, and save money with extended oil changes. In addition to lubricating moving . Obviously, the latter is the much preferred option for automobile owners, who have a significant investment in and need for a well-functioning and durable engine. A new bench test instrument and technique were developed to indicate any tendency of the test oil to gelate. It goes without saying that the higher quality of oil you choose, the more expensive it’ll be. It is the only known viscometer capable of doing this. When dirty oil starts circulating in the engine, contaminants may build up within and cause malfunctions. The oil’s molecular friction, which separates two surfaces in relative motion, requires energy to overcome it. I think 10,000 kms is the sweet spot. Not too early, nor too late. Shell Rotella (550019921) T6 5W-40 Full Synthetic, Heavy Duty Diesel Engine Oil (CJ-4) Buy now on Amazon. Because of this, restaurant operators concerned with guest experience are implementing oil quality monitoring programs to ensure their guests get the best quality fried foods. With the exception of 2012, the increase in V-FEI is equivalent to nearly 7 to 8 percent in viscosity-dependent fuel efficiency. Checking and changing your car's oil at regular intervals is important for the health of the engine, to ensure your car is running efficiently. Handheld TPM measuring devices are generally more accurate (usually to within 90%) and remove the subjectivity of the other previously mentioned methods. The smaller the number, the better it will flow. Integrated TPM measuring devices, which are integrated directly into a fryer’s plumbing, are also very accurate (within 90%), and because there is no handheld device, it is less likely to be dropped and/or abused. The technique was accepted by ASTM as test method D4683 for use at 150 degrees C (and more recently as D6616 for use at 100 degrees C). API’s Engine Oil Licensing and Certification System (EOLCS) is a voluntary licensing and certification program that authorizes engine oil marketers that meet specified requirements to use the API Engine Oil Quality Marks. It’s about finding the right method that works for you and your staff. Over a 24-hour period, a number of engines containing oil were ruined. This not only showed the oil’s tendency to become flow-limited but also specified the degree of gelation that might occur over the measured temperature range (typically minus 5 to minus 40 degrees C). Scientifically speaking, fresh cooking oils are naturally non-polar and almost pure triglyceride, meaning their compounds are symmetrically shaped and not “broken-down.” During the frying process, air, moisture and heat are introduced to the oil. So a 5W-30 will flow easier than a 10W-30 at start-up temperatures and a 10W-30 will flow easier than a 10W-40 at normal engine operating temperatures. The technique, which involved continuous low-speed operation of a cylindrical rotor in a loosely surrounding stator, was immediately incorporated into engine oil specifications and later became ASTM D5133. In the US, where oil is not currently regulated, most operators rely on visual inspection and discard oil based on foaming, odor, smoking, color changes and/or by taste of food products. Once you've found the right engine oil, buy online from the biggest and best independent online supplier of motoring oils & fluids. With an eyedropper, an oil sample is taken from the vat and matched against the provided guide colors. The first was simply related to high viscosity and called flow-limited behavior. This critical bench test of engine oil quality became known as high temperature, high shear rate (HTHS) viscosity. Otherwise the dipstick will read slightly low. Save my name, email, and website in this browser for the next time I comment. As a consequence, the SAE has introduced three new operating grades identified as SAE 16 (2.3 cP minimum at 150 degrees C), SAE 12 (2.0 cP minimum at 150 degrees C) and SAE 8 (1.7 cP minimum at 150 degrees C). The oil should be brown, translucent and full. You should check your oil levels when your engine is cold. The air-binding engine oil that caused the Sioux Falls failures provided a solid case study. Given the influence that oil viscosity has on the engine, a technique was developed to calculate the effects of engine oils on fuel efficiency. Since viscosity is directly related to the amount of energy expended by the engine for wear protection through hydrodynamic lubrication, such a decrease in viscosity would be expected to have important benefits in fuel efficiency but only in engines designed for their use. The oil change light in your vehicle will illuminate when there’s not enough oil in the system, so check the dipstick to see what’s happening. The reduction of the PEI to 6 to 10 milligrams per liter of engine oil is a significant change in protecting the catalytic converter from the effects of phosphorus. Low oil pressure - indicated on the oil-pressure gauge or dashboard warning light - could provide an indication of wear or damage to the pump. Turn off the engine. Best high performance synthetic oil. Wait at least 10 minutes after use before checking to ensure you get an accurate reading and don’t accidentally burn yourself on a hot engine. It is best to check the oil in the morning before the car has run, as all of the oil will have run back down into the oil pan. The Official Lubricheck Oil Tester demo. Figure 3 shows the average value of SAE 0W-20 and 5W-30 engine oils from the North and South American markets from 2008 to 2014. Our own Kimberly Eros, answered some questions on the different methods of oil quality testing and how your restaurant can use them to your benefit. This oil is intended for all gasoline engines currently in use and has been the standard since 2004. It should contain information on how to check the oil in your vehicle. Ensure your vehicle’s parked on level ground and your engine is cool. I assume you have a German made, over engineered contraption. Some newer cars have electronic oil monitors and don't have traditional dipsticks for manual inspection. Do not fill up over the maximum level. Accordingly, these polymer-containing oils were listed by the SAE viscosity classification system as multigrade engine oils, as they met the requirements of both viscosity temperature zones. to check the engine oil, first locate the engine oil dip stick on the side of the engine (figure no 1). We stock a massive range of fully synthetic, semi synthetic, and mineral engine oil service kits, all picked by lubricant experts and including enough oil for a full change and a disposable filling kit (funnel, gloves, wipes). This was a considerably more serious issue, as lack of oil pumpability could destroy the engine. With no oil, too little oil, or old and worn out oil, an engine can be severely damaged or destroyed.Oil is responsible for lubricating all major components of the engine, reducing the wear and tear on the engine, and helping dissipate the heat generated by the engine. They also work for any oil type (vegetable, animal, or vegetable/animal blend). Open your bonnet and locate the dipstick. For diesel engines, the current top oil rating is CI-4. With the oil color guide tubes, the major advantage is cost. Each model vehicle may have a different oil capacity. The engine oil level should be in the cross hatch section and at or slightly below the full mark when the engine is cool. They do, however, come with just an 80% accuracy rate, which is less accurate than TPM methods. These are some of the methods they’re using today: The darker color in the Oil Color Guide Test Kit represents an oil color that’s reached the end of its useful life when frying proteins. A decade ago, the lowest SAE viscosity grades were SAE 0W-20 and 5W-20 oils, with SAE 20 carrying the minimum high shear rate viscosity of 2.6 centipoise (cP) to simulate engine operation at 150 degrees C. Figure 2 shows data from engine oils sold in North and South America as well as for SAE 5W-30 engine oils. Engine oil is one of the fundamental products needed to run your car, as it lubricates the engine to prevent the pistons seizing or exploding.. Check the smell of your engine oil. Why your oil analysis needs to evolve the same way your oil has For years, Total Base Number (TBN or BN) has been used as one of the key measurements in the field to help determine remaining oil life by indicating the amount of performance-related additive left in the engine oil. Now, pull it out and be ready with old fabric or rag to wipe and clean the dirt off of the dipstick. Also shown is the specified maximum volatility set by the International Lubricant Standardization and Approval Committee (ILSAC). Our guide can help you make the right choice Reinsert the dipstick, pull it out and check the oil. Required fields are marked *. The data reveals that phosphorus volatility generated by the Selby-Noack test is virtually unrelated to the amount of phosphorus present in the oil as an additive. For comparison, the average V-FEI for SAE 0W-20 and 5W-30 in an earlier study was 46 and 47 respectively. The second was less obvious and involved the gelling of the oil under a long, deep cooling cycle. Engine oils were collected directly from the market and analyzed by selected laboratories through a series of bench tests. hbspt.cta.load(3951034, '0185d019-b885-48b3-81bb-598c6269bb64', {}); Therefore, viscosity can be defined as a form of molecular friction. Each model vehicle may have a different oil capacity. The oil remaining after the loss of the more volatile components will also be more viscous and energy-absorbing. The Engine Light is On. In the winter of 1979-80 in Sioux Falls, South Dakota, a cooling cycle showed that air-binding could occur under relatively mild cooling conditions. This was considered important in lubricating engines that operated at high shear rates (as measured in millions of reciprocal seconds), in contrast to the several hundred reciprocal seconds of the low-shear viscometers then being used to characterize engine oils. API’s Engine Oil Licensing and Certification System (EOLCS) is a voluntary licensing and certification program that authorizes engine oil marketers that meet specified requirements to use the API Engine Oil Quality Marks. It’s easy to do, but can cause major damage requiring thousands of dollars of repairs. Viscosity may be defined as a fluid’s resistance to flow. In the early years of automotive engines, oils were simply formulated and obeyed Newton’s equation for viscosity - the more force used to make the fluid flow (shear stress), the faster it would flow (shear rate). Minimum limits were then imposed for various grades in the SAE viscosity classification system. A black or brown color indicates normal, healthy oil. As cooking oil degrades, it affects the texture, taste and overall flavor experience of the food. The instrument was called the tapered bearing simulator viscometer. In the API's words, SM oils are \"designed to provide improved oxidation resistance, improved deposit protection, better wear protection, and better low-temperature performance over the life of the oil\" [source: API]. You need to check motor oil before any long trip to avoid major damage. The most obvious alert that there’s an issue with your oil will come from the car itself. However, they were no longer Newtonian in flow characteristics, as the viscosity was found to decrease with increasing shear rate. None of these lower grade oils has yet to reach the market for analysis. Many types of crude oil are produced around the world. Reinsert the dipstick, pull it out and check the oil. An old t-shirt usually works great. Figure 5 shows the change in PEI over the last eight years. Of all the engine oil’s physical and chemical qualities, its viscosity and viscometric behavior during use are often considered the most important. Without proper timing of internal engine components, the engine will suffer a catastrophic failure. A TPM reading >25% is considered the discard point in many European countries, although the threshold is dependent upon local regulation. Another aspect to consider when reducing the viscosity in engine oil formulations is that such a reduction is most frequently obtained by using base oils with higher volatility. Therefore, careful formulation of the oil viscosity is critical to vehicle owners and to governments mandating fuel economy limits. This is a significant amount of energy from the engine in exchange for the provided wear protection. You should check your oil levels when your engine is cold. The SAE rating actually refers to the function and viscosity of any given engine oil. Warning: Never check the oil when the engine is hot. Your email address will not be published. This triggers the Low Engine Oil Light that most cars are equipped with. A first quality synthetic engine oil; Works well in all weather conditions; Can be used on Sprinter vehicle models; Cons: May not be suitable for some engines which may require different oil viscosities, check instructions. The best way is to check your engine oil level at frequent intervals. Dipstick or not. This way, if there is something wrong you could spot it at an early stage. This involves using laboratory bench tests designed to correlate closely with engine dynamometer tests or field experience. As engine design has progressively increased power from smaller engines, the difficulty of establishing repeatable dynamometer tests has grown even more rapidly. Why you need it A lighter, milky color could mean that coolant is leaking into the oil. Engine oil is required for its mechanical components to be lubricated and to function properly during operation. the engine oil is the fluid used to lubricate the internal mechanisms of the engine. For example, my 4.3 L engine in my blazer takes 4 1/2 quarts of oil. Monitoring oil quality is a fail-safe and objective way to ensure an operation’s food quality. Jan 5, 2017. This inability of the intervening oil to escape quickly and its level of incompressibility hold the two surfaces apart and prevent wear, a process that is termed hydrodynamic lubrication. With easier engine startability at low temperatures, another problem became evident - oil pumpability. Next, check the oil level via the dipstick. The energy required to overcome this molecule-to-molecule attraction and produce fluid flow can be considered a form of friction. Interestingly, it was later shown that this instrument was unique and basically absolute in providing measures of both shearing torque or shear stress and shear rate while operating. Monitoring an operation’s oil quality is always a good thing as it helps ensure tasty, quality fried foods for your guests. Coolant should be full and contain antifreeze, which is typically green in color. How to check the oil Allow the car to cool - Let the vehicle cool down before attempting to check the oil. You cannot. This training will ensure the consistent delivery of high-quality fried foods for your guests and allow for maximum oil usage, which lowers operating costs. If the engine oil is low, it could indicate the engine is either leaking or consuming oil. Motor oil is the lubricant between the moving engine parts; if the level is too low, the parts will wear quickly and increase likelihood of engine seizure. Follow these simple steps to check your vehicle’s engine oil: 1. Manufacturers recommend changing your engine oil every 12 months or 9,000 miles, whichever comes sooner, but you should still check your engine oil at regular intervals to ensure your car remains safe to drive. If you really need to check the condition then you have to take a sample and send it to a lab. In between your regularly scheduled oil changes, you can check your engine oil levels to ensure that it has not become too low or dirty. Consequently, choosing an engine oil to meet particular service needs and conditions requires knowledge of several important oil properties, including viscosity. With this value, which ranges from 0 to 100, the higher the V-FEI of a given engine oil, the less energy is lost to viscosity, and consequently, the more fuel efficient the engine is. Making sure there's always enough oil is the easiest way to ensure that you avoid catastrophic engine failure and the huge repair costs that go with it. Fortunately, once the quality level has been determined on the dynamometer or in the field, there is a much less expensive approach that can be applied to more precisely appraise the oil quality.
