Conventional lubricants are refined from crude oil and contain impurities that cause them to oxidize and break down under high temperatures. A common sign is a change in the oil’s texture or color; fresh oil is typically amber and translucent, while dirty oil appears dark and gritty.
How Often Should I Get Oil Change: Understanding Intervals and Factors
If your vehicle requires synthetic oil, you can often extend your change intervals safely to 7,500 or 10,000 miles without risking engine damage. The engine in your car is a complex assembly of moving metal parts, and motor oil serves as the critical lubricant that prevents friction from causing catastrophic damage.
Manufacturers often define "severe service" conditions, which can significantly shorten the life of your oil. This rule was largely based on the technology of conventional motor oils, which contained fewer additives and broke down more quickly under the heat and stress of combustion.
