I've heard of some sort of "engine flush" that you add to your oil right before you do an oil change. You're supposed to have the car warm, add the fluid, then idle for about 5-10 minutes. It's supposed to dissolve contaminates so they don't precipitate to the bottom or other surfaces.
Are these sorts of things legit? Or are they a bunch of snake oil? (Or Lucas Oil. Haha)
If this IS a good idea, what products would you guys recommend I look for?
