Finally, the measurement procedure is time-consuming, which can interfere with labor, and is dependent on proper operation. 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). How to check motor oil level. This same molecular friction prevents the oil from escaping too quickly when two engine surfaces in relative motion are brought closely together under pressure. Save my name, email, and website in this browser for the next time I comment. Unfortunately, in the years following the catalytic converter’s development, it was discovered that certain elements in gasoline or engine oil, including phosphorus and sulfur, would deactivate the catalyst by coating it. To do this, simply dip your dipstick and sniff it. However, the subjectivity of measurement is a drawback. 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. Dipstick or not. The air-binding engine oil that caused the Sioux Falls failures provided a solid case study. MOT checklist and comprehensive guide; Which is the best oil for my car? In the mid-1900s, the reciprocating engine was identified as a major contributor of air pollution. Consequently, choosing an engine oil to meet particular service needs and conditions requires knowledge of several important oil properties, including viscosity. Jan 5, 2017. 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. It’s easy to do, but can cause major damage requiring thousands of dollars of repairs. 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. Engine Timing Chain Wear: Why Oil Quality Matters. 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. 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. 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. Additionally, each strip is single-use only, so they’ll need to be replenished at an average cost of $300 per year, this method is more expensive than some of the more scientific options. In cold-room dynamometer tests, it was determined that there were two forms of the pumpability problem. Why you need it The engine oil quality is critical for the life of the engine. Consider … In order to run properly, a car needs oil. This involves using laboratory bench tests designed to correlate closely with engine dynamometer tests or field experience. As a consequence, exhaust catalytic converters were developed in the 1970s to treat the exhaust gas and convert it into carbon dioxide and water. 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. to check the engine oil, first locate the engine oil dip stick on the side of the engine (figure no 1). Method 2: Check oil via the instrument cluster. As cooking oil degrades, it affects the texture, taste and overall flavor experience of the food. Lowering oil viscosity can be an important step in reducing viscous friction to improve fuel efficiency. 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. These engine oils are likely to be more harmful to the exhaust catalyst. Oil Color Guide Test Kit: Oil color examples are provided in pre-filled tubes that display oil colors nearing their discard point (these differ dependent upon products being fried). If you can’t find one on your vehicle, check the owner’s manual for how to check your oil. 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). Which engine oil does my car need? The FFA strips are easy to use and don’t add any interruptions to frying time. You cannot. For more answers to your questions regarding oil quality testing or any other technical question about your Henny Penny equipment, visit Henny Penny’s Technical Support site or contact the 24-hour technical support center at 1-800-417-8405. Your email address will not be published. After your quick oil change service is completed, One of the first things that you want to check is that the oil is filled to its proper level. This knowledge and bench test, which initially seemed to predict both forms of failure, were not enough. This determination can only be made by using the oil or pre-testing it. Part of the series: Repairing Motorcycles: DIY Maintenance. The Engine Light is On. Given the influence that oil viscosity has on the engine, a technique was developed to calculate the effects of engine oils on fuel efficiency. The best advice you can give your filter customers is to buy the best oil filter that is listed for their engine — especially if they are not changing their oil for 7,500 miles or … These results suggest that volatility control may be less demanding with the more recently classified multigrade oils identified as SAE 0W-16, 0W-12 and 0W-8. Required fields are marked *. The dipstick is connected to the oil tank in your engine, and is used to determine how much oil is still in the oil tank. PETROLEUM QUALITY INSTITUTE OF AMERICA SAMPLE SUMMARY/PASSENGER CAR MOTOR OIL Passenger car motor oil is the lifeblood of your engine. It is normal for an engine to consume a small amount of oil during the engine oil change interval, but it should not be excessive. With the oil color guide tubes, the major advantage is cost. If the oil doesn’t drop from the dipstick, it might mean it’s already time for a change. In the US, where oil is not currently … I assume you have a German made, over engineered contraption. When the car is in motion the oil splashes around and covers the entire stick. They do, however, come with just an 80% accuracy rate, which is less accurate than TPM methods. To check your oil level you need to start with a clean stick. However, using the engine to measure oil quality in dynamometer tests can be an expensive proposition. 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. Minimum limits were then imposed for various grades in the SAE viscosity … Fried food quality is a function of oil quality. The energy required to overcome this molecule-to-molecule attraction and produce fluid flow can be considered a form of friction. Chemical reactions that lead to changes in the oil, which can affect food quality the longer it’s used. It's best to check your oil after your engine has been turned off for at least 10 minutes so the oil can settle at the bottom and cool off. A black or brown color indicates normal, healthy oil. Shell Rotella (550019921) T6 5W-40 Full Synthetic, Heavy Duty Diesel Engine Oil (CJ-4) Buy now on Amazon. the engine oil is the fluid used to lubricate the internal mechanisms of the engine. To serve the engine, oil must possess certain physical and chemical properties. However, there’s a lot in addition to oil quality testing that an operator can do to ensure their fryer oil stays fresh as long as possible. Density ranges from light to heavy, while sulfur content is characterized as sweet or sour. 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. The thing is that while the quality of car engine oil really matters, of equal importance is its grade. Unfortunately, for the uninformed automobile owner, a high-quality engine oil and one of poor quality will look and feel the same. It delivers the ultimate food sensory trifecta: “GBD” or “golden, brown and delicious.” However, repeated usage of frying oil causes it to degrade. Turn off the engine. Is any one of these methods preferred or recommended over the others? Ensure your vehicle’s parked on level ground and your engine is cool. Email *. 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. Monitoring oil quality is a fail-safe and objective way to ensure an operation’s food quality. Advertisement . Check the quality of the oil as well by rubbing it between your fingers. If you’re unsure where this is, check your user manual. Figure 6 shows the phosphorus content in a number of SAE 0W-20 and 5W-30 engine oils vs. the PEI values obtained. 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. What oil change interval do you stick to? An employee erring too often on the side of disposal when the oil could be used longer, results in higher oil usage and operational costs. Today, engine oil specifications for multigrade oils require a maximum gelation index of 12. 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. Open your bonnet and locate the dipstick. Readings are taken automatically during filtration processes and are typically more consistent and accurate as there is even less room for human error. Viscosity may be defined as a fluid’s resistance to flow. The Ford IOLM system is not just a simple oil quality sensor, but a software based, algorithm-driven device that takes into account various operating conditions of the engine to determine when the oil needs changing. Most people overlook checking engine 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. A TPM reading >25% is considered the discard point in many European countries, although the threshold is dependent upon local regulation. Engine oil is required for its mechanical components to be lubricated and to function properly during operation. have become very popular. Save my name, email, and website in this browser for the next time I comment. Soluble phosphorus compounds such as zinc dialkyldithiophosphate (ZDDP) have been used in formulating engine oils for many years. Also the feeling the oil with your on your finger can help too. 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. There are several different methods used to measure oil quality ranging from subjective visual inspection to more objective, scientific measurements. Are there any other best practices for these testing methods operators should be aware of? 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).
