Helps to protect the engine under severe operating conditions.Reduces engine wear and helps to extend engine life.10W-40: 10W refers to the low-temperature viscosity ('Winter'), 40 refers to. Multigrade oils must fulfill two viscosity specifications, their viscosity grade consists of two numbers, e.g. Oils can be separated into multigrade oils and monograde oils. Lowering the current viscosity limit to 3.8 cSt. The viscosity grade of a lube oil is determined by the Society of Automotive Engineers (SAE). Revised SAE J306 is economical as well as a help to reduce greenhouse gas emissions. This ISO viscosity classification is consequently based on kinematic viscosity at 40C (104F). A new standard for automotive gear lubricants is an important factor towards the drive for greater fuel economy. Where non EP gear oil is specified or required. The aforementioned SAE J300 classification contains, however, guidelines (nominal range) for kinematic viscosity measured at 100 C, and for oils of class. For engine oil viscosity classification SAE j300 viscosity chart click this link.SAE 20W-40 misses out on both the SAE 20 and 30 ranges, and so on. Can be produced with red colouring for easy identification. Table 1 - Minimum Requirements for Multiple Viscosity Graded Oils is.Where a SA, SB, SC, SD, SE, SF, SG or SH monograde 30 oil is required.On the other hand, SAE 5W-20 will always flow better than SAE 20W-50. But when you’re driving, the SAE 10W-30 will flow better as the oil will get hot and its hot oil viscosity grade of 30 is lower than 40 of the other engine oil. For use in most 4 stroke lawnmower engines. In other words, SAE 0W-40 will flow better than SAE 10W-30 when it’s cold as 0W is less than 10W. ![]() The other grades are all available in the standard golden brown colour. 0W-16 SAE AMERICAN PETROLEUM INSTITUTE CERTIFIED. See the ILSAC STANDARD FOR PASSENGER CAR ENGINE OILS chart on the next page for descriptions of current and obsolete ILSAC standards. Automobile manufacturers recommend oils that carry the API Certification Mark Starburst. The applications for this oil are usually in small engines found on lawnmowers, small diggers, generators and other small air cooled engines, as well as some gearbox applications, both automotive and industrial where a straight mineral oil without EP additives is required.Īegis SAE 30 is produced using two colour formulations, the standard golden brown colour, and for easy identification from other oils it is available in a red colouring if required. This mark cannot be applied to oils of the 0W-16 viscosity grade. Aegis SAE Mineral Oils are blended using an additive package designed to reduce wear, and to help reduce oxidation and to help keep engines and gearboxes cleaner. Aegis SAE mineral oils are a range of straight grade minerals oil designed for use where a mono-grade oil is required.
