After using M1 5w30 in my wife's Cavalier, gas mileage went up from 27 mpg to 31 mpg. I'm starting to see the benefits of this stuff already!

I sure agree here. Objective as we think we are-there is a subconscious urge to try for better milage when you are using a product that hopefully will improbe milage. For instanceyyou will resist the urge to do the things in a car that are fun-but unfortunately waste fuel.quote:

Sorry but I'm not a believer in huge MPG increases when choosing different oils (your's is 15%). The largest percentage gain that is observed when switching oils is when you switch grades (5W30 compared to 10W40). The maximum percentage increase is about 3% for each change in grade. Going from a 5W30 conventional to a 5W30 synthetic won't save you much gas. Too many people change driving styles, fuel type, or something else that changes their MPG and the driver thinks it is just the oil. Hey, but any increase is $$$ saved.
