How Many Categories Does Full Synthetic Oil Have?
3 Answers
Full synthetic oil is divided into two categories: PAO-based full synthetic oil and Group III base oil full synthetic oil. Below is relevant information about synthetic oil: 1. Characteristics: Full synthetic oil offers better high and low-temperature performance; has a longer oil change interval; and is suitable for more severe vehicle conditions. 2. Grade: Currently, full synthetic oil is mainly classified as SN grade. The API on the oil stands for the American Petroleum Institute, and it is divided into SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, and SN grades, with each grade improving in quality. SN grade is currently the highest-grade oil available.
As an avid car enthusiast who frequently researches vehicle maintenance, I've discovered that full synthetic oils are primarily divided into three categories: The first is the PAO base oil type, also known as Group IV, which offers excellent durability and is suitable for high-performance engines. The second is the ester-based oil type, classified as Group V, providing top-tier lubrication but at a higher price point. The third is the blended base oil type, such as Group III with synthetic additives, offering good cost-performance but sometimes being controversial. Different classifications affect viscosity choices like common grades 5W-30 or 0W-20. Selecting the right type can protect the engine and reduce wear, especially crucial during high RPMs or extreme cold weather. I also recommend checking the manufacturer's recommended type in the vehicle manual when purchasing oil, and avoiding counterfeit products just to save money. Overall, understanding these classifications helps car owners make wiser maintenance decisions for their beloved vehicles.
In my long-term hands-on experience with vehicle maintenance, fully synthetic motor oils can be roughly categorized into three types: The first is PAO-based, which has excellent high-temperature oxidation resistance, and I often use it for long-distance driving; the second is ester-enhanced, suitable for racing or high-load engines; and the third is a regular synthetic blend with mineral oil, which saves money for daily city driving. Don't just focus on the classification—consider the API rating like SP or SN and match the viscosity to your car's needs. When changing oil myself, I often check the oil color changes and find that blended types tend to thicken quickly. Regular oil change intervals of 5,000-8,000 kilometers ensure smooth engine operation and prevent premature major overhauls.
