Cameron Evans of Red Line Oil says there are definitely differences to be aware of. "It may seem to be a pretty simple equation when you're making a racing oil. Everyone knows that you change race oil frequently, so you don't need detergents in racing oil. But blending oil is a bit like making a cake: you may have a quart's worth of ingredients to blend into the batter, and if it didn't need to be sweet then there would be more room to blend in something else. In passenger car oil the detergents allow the deposit to be either suspended in fluid or picked up by the oil filter. With race oil it's a bit different because you don't have that same ability. When you look at racing oil, you can remove the detergents that take up much of the room in the additive package of a passenger car oil. It leaves more room for lubricity additives this way."
