please do not use any oil additives you would be wasting your money a good synthetic oil is made to protect your engine the best without any help these magical additives are usually nothing special one of my friends bought z-max once it appeared to just be mineral spirits with coloring added side by side we could not tell them appart the z0maxs was then returned. about 3 yeara ago my cousin had a motor go bad in his dodgr stealth he used dura lube when we rebuilt the engine there was a kinda sludge about it was spent teflon teflon breaks down when it gets hot not good for engine
DONT USE ADDITIVES THEY R BAD!!!!!!!!!!!!!!!!!!!

Snake oil, all of them.

ZMax is just mineral oil. Not very good if you like the seals in your engine to be intact.

Alot of others use Teflon, also not good in your engine.

There are no amazing products you can dump in and gain 20+ HP.

The best thing for your engine is to make sure you change the oil and use a quality filter.
