Marvel Mystery Oil?

[sdg3205]

Has anyone used this in their fuel or oil?

Is it as awesome as it sounds?

I've used it. It's been around for years. When I worked at WalMart in the automotive department, lots of old-timers bought that stuff up as well as Rislone oil treatment.

I use the MMO in the fuel tank for lubricating the fuel pump & top end of the engine. Like any other additive, you can't tell if it's really doing anything or not. It's one of those things that you like to think helps & does what it says.

It's cheap enough to use for what it advertises.

I used Rislone when I would get a noisy lifter in my old daily drivers. It stooped the noise in 30 seconds.

I used it in my old Isuzu rodeo that had the very common lifter tick on it. I would change the oil with 20w 50 and poor a quart of the marvel in it and after a few hundred miles the knock went away! but it would come back when the oil got dirtier, but everytime I changed it after that few hundred miles the knock would leave, and i tried different products but only when I used the marvel the knock went away. Im not saying its gonna fix all your problems but it helped the Isuzu tick
