What do you guys think of this product? I’ve used it before in my fuel system and vacuum lines but never in my oil. I was wondering has anyone used it in there oil right before there oil change?

before the oil change is do. then change the oil and
filter as normal.Great product.

What do you think of marvel mystery oil? Is that any better or about the same?

i have tried a bottle before, and noticed a small difference. so small that only I and no one else would have noticed. if u got 10 buck such give it a shot.

If there is any amount of sludge build up inside your engine flushing additives are a poor idea. You might just open a huge hornets nest you didn’t count on.

If the engine is clean inside you shouldn’t need to add anything before changing the oil.
