I think MMO is 1950's technology. You have Mobile 1 today and I would not mess that up.

Take a good look at the MMO. Looks just like transmission fluid doesn't it. Tranny fluid will work as an additive just as well as MMO. Been there, done that.

In my 45 years plus as an auto/truck mechanic I am not a beleiver in additives but I have used MMO to free up stuck hyd.lifters and remove water from automatic transmisions when the trans cooler fails so it does have its uses but as far as just puting it in your engine or gas for preventive maint. NO.

I added the recommended amount of MMO to my 1999 Jeep's oil and gasoline when it had only 765 miles on it on December 12,1999. It now has 100,750 miles and the engine still runs smoothly.

Was that the last time you changed your oil?

I only change the oil on my '99 Tahoe, top brand oils.
140k, runs smooth, original plugs, wires, and air filter.
MMO not needed with modern oils.

I can't believe Marvel's Mystery Oil is still on the market. I will NEVER consider putting it in my Cummins engine, Allison transmission or Honda CR-V. Last report I read from an independent lab showed MMO actually degraded oil and made the engine components wear faster.

I guess I'm one of those old school people when it comes to MMO. I don't believe there's any benefit putting it in the oil though. Freeing up stuck hydralic lifters?! Geeze, you gotta really be neglecting your oil changes for your lifters to get that gummed up. As far as using it in gas though. I've used it in the gas on our motor home with good results, for both the Chevy 8.1 engine and the Onan 7k genny. Motor home had sat for several months prior to our purchase and the engine had a little stumble and the gen would skip a ocassionally. I talked to a generator mechanic and he suggested the carberator on the gen may have varnished. Something that can occur in generator and boat motors. I considered SeaFoam, but didn't want to pay the price. Ran MMO through tank as directions instructed. Motor home engine started running smoother, as did the generator. I wouldn't go so far as calling it snake oil. It works well to disolve varnish deposits on injectors or carberator jets and also acts well as an upper cyliner lubricant. Beyond that, I wouldn't use if for anything.

The 351 in my '91 E350 had right at 200k when I took it out of service. It ran just as good as it did when I bought it at 10k. I took very poor care of it. The only motor problem was a rear main seal leak because I took just as poor care of the transmission and it got so hot it fried the rear main. To my credit the manual said that the transmission fluid never need to be changed and I took it as such, it got replaced at 175k when it was too late. I did replace the plugs at about 120k and had to replace them again when the diaphram in the fuel rail pressure regulator got a hole in it and the got fouled. point being......hell I don't know.
