Marvel Mystery Oil????????

[midway paul]

I love this stuff. Found out about it back in the 60s from a retired diesel mechanic. It's worked everytime I've used it. I usally add it to the oil about 300 miles before it's going to be changed. Well maintained engines don't "need " it but it doesn't hurt. Those that buy abused engines can sometimes benifit from it's property's if things aren't to bad. Stuck lifters and clogged passages get opened up with MMO.

What say you, true mechanics? bp

The only downside I can see is MMO loosening up deposits & possibly scoring cyl walls & bearings with those deposits being pumped back into the oiling system. But if the engine is in poor shape anyway, why not give it a shot.

I had a 350 engine that had an intermittent miss.

I started changing out the plugs first then the plug wires and yet the miss was still there every once in a while.

I then changed the vacuum lines thinking maybe the spark was jumping around but that was not it either.

I then pulled the distributor thinking the shaft might be shorting out from time to time but that also did not fix the problem.

We checked the battery and all kinds of stuff with no luck.

A good friend of mine who is in his late 70's told me to try one quart of Marvel Mystery Oil and when I asked him why he said I think you have a lifter that is handing up every once in while and that's just what the problem was.

Once I added the Marvel Mystery Oil I never had the problem again.

Crazy thing is it really felt like an electrical problem and it was not.

Great product with many uses and it really works. Jimbo
