engine oil

Engine Up ah... look like some kind of fake blue pill, you car will get stroke any time after using it.

it might cause expensive repair so you shouldn't put it on your engine

as a season user and train engine oil expert, give me bottle of various brand of same viscosity engine oil, and pour down and run it, I will not able to tell you which brand is different from A B or C. It is almost impossible.

How ever, if you pour down a 50wt vs 30wt engine oil from fresh service, yes, definitely most people will able to feel the heavier pedal.
