Marvel mystery oil
your crankcase before an oil change, drive around,
then change the oil.
Supposedly, you can put a few ounces in your gas
and it works like STP to clean your injectors &
fuel system. I have yet to do this, but it would
be a lot cheaper than STP for this purpose --
assuming it works.
Does anyone know of some real research on this? I
put it in with my oil before my last change and
before a 60 miles drive, but another mechanic
opined that it is too thin to adequately protect
I'll say this. It *does* smell good. MMMM
I'd appreciate any real-life experience, even
anyone who has good reason for calling me a dope
for using it.
