Does anyone use marvel mystery oil? If so have you noticed any difference in your truck? I want to start using it in my gas just to lube everything up.

 

**** everytime i drink it my farts come out so much smoother... throw close to a quart in your crank case and put about 4-8oz in your gas tank....
clean your throttle body and run some cleaner through your pcv valve as well, do it all at once...

 

Grampa wore a squirt can of the stuff on his side holster he used to fix EVERYTHING, to hell with WD-40. **** I think he even used it to lube grandma up...

 

i have found that the lucas oils products do a much better job than the marvel mystery oil.and usually i can feel a difference right away.

 

As a long time truck driver (used to be an owner/operator, but sold my Kenworth years ago...), I have to agree with the stuff about Lucas products. I also noticed that they have a 100% synthetic version of their oil additive, as well as the original. In the big truck, I noticed measurable gains in my overall fuel economy with Lucas Oil Stabilizer. Granted, it was only 3-4%, but in a vehicle that does thousands of miles a week, and only gets 4-5 mpg, that adds up.

As far as Marvel Mystery Oil goes, I've heard good things about that, as well. Not so much as an oil additive, but from the guys who add it to the tank with fill-ups. Most of them are old school hot rodders, running carbs on big V8's, but they have all said that MMO does keep the carb cleaners & gets rid of minor varnish.

I would have to wonder about MMO's compatibility with modern synthetic oils, though. Not saying I've heard anything bad, but I'm curious.

 

wow...
