I have heard that Marvel Mystery oil works great in older cars with carbs to
keep them clean.

How well does it work in newer cars to keep injectors clean?

How about in the crankcase?

How bad does it bugger up the converter?

Just wondered. Thanks in advance!

It might do something, but probably there's enough cleaner in the gas to
keep the injectors clean anyway and a real injector cleaner would do a
better job if they were dirty. I think MMO works somewhat to clean out oil
deposits from a dirty engine, but with modern oils I really don't think it's
necessary. A bottle of it I saw recently said it's safe for oxygen sensors
and catalytic converters. It wouldn't hurt either of those anyway unless it
had some kind of unburnable residue.

I used MMO in the crankcase oil of every car that I owned for 30
years. I would add a pint a few hundred miles before every oil
change. I learned to do that from my father, who had learned it from
my grandfather, who was a garage owner and Ford dealer back in the
1920s and 1930s. MMO is truly an old fashioned oil treatment, and I'm
sure that it really extended engine life back when the best stuff you
could get was 30W non-detergent oil.

I never had an engine problem when I used MMO and several went to over
200,000 miles. It kept the engines very clean inside. I think that it
helped the seals, too, because I never had any bad oil leaks.

I bought an Oldsmobile V-8 in the 1970s with over 100,000 miles on it
and it had a lifter "tick" for the first few minutes after startup. I
put a double-dose of MMO (a quart) in and the noise went away in a
hundred or two miles. Following the practice of using it at every oil
change after that, I drove it up to about 225,000 miles before I sold
it and I never heard that "tick" again.

I haven't been using it in my present two cars, though, since I've
started using Mobil 1. It is supposed to keep the engines clean inside
and I'm not sure about mixing MMO with synthetic oil. MMO sure is good
stuff, though.

Marvel Mystery Oil is an upper lube(valves,rings) when used in fuel and
won't hurt anything.Used in the crankcase,it cleans it. Good stuff!!!! I use
it all the time.
