Types of Motor Oil

Types of Motor Oil Motor oil can be segmented into four basic varieties-synthetic oil,synthetic blends,high mileage oil and conventional oil. Synthetic motor oil is a laboratory synthesis of precisely controlled ingredients created by oil engineers,scientists and chemists. When combined with a high-performance additive package,this results in an oil with the highest levels of lubrication and engine protection,generally offering better protection at startup,better cleansing qualities,enhanced durability and better protection against heat buildup.To carry this symbol on the container,the oil must meet the most current requirements of ILSAC,which is the International Lubricant Standardization and Approval Committee,a joint effort of . and Japanese automobile manufacturers. The Starburst is typically found on the front label on SAE 0W-20,SAE 0W-30,SAE 5W-20,SAE 5W-30 and SAE 10W-30 motor oils. The API"donut" Motor Oil Donut Another identifier on motor oil containers is the API"donut"typically found on the back label. It's divided into three parts x431 v. The top half of the circle (2) indicates the API service rating,also called the performance level. The center of the circle (3) denotes the SAE viscosity,which we just discussed. The lower half of the circle (4) indicates whether the oil has demonstrated certain resource conserving or energy-conserving properties. In the top part of the donut the words"API Service XXXXX"(5) indicate the type of engine and performance the oil provides Creader VI. API Service SN the current rating means"S"for Service Station oil (for gasoline engines) and N the current level of service. Or it will say"API Service CJ-4."API service CJ-4 means"C"for commercial engines (diesel engines) and J-4 where J is the current performance level and 4 indicates a 4-stroke diesel (a 2 will be used for 2-stroke diesel engines). Check your owner's manual for the recommendation for your vehicle. Older vehicles can use the current designation. All designations are compatible with those that preceded them with the exception of a few antique vehicles. Only the current API categories are indicated within the donut.
