MMO VS. SEAFOM

imported post

You know my answer! :gunhead:

Never actually used MMO but I have used Sea Foam on every engine I have except my weed eater. Never been disappointed. :clapper:

There was a similar question on an auto forum Ibegan going to when I bought my Ford Crown Victoria Police Interceptor (P71). After lots of posts and discussion, Sea Foam was preferred over MMO by most people on the forum.

If you use "MMO" on a regular basis you'll never need to use "Sea Foam"!

I believe "Sea Foam" is stronger than "MMO" and works great!

But "MMO" keeps your bike working great and doesn't harm the seals, etc.!

I like both!

Apparently I may have found a source for Seafoam in Winnipeg. Apparently Piston Ring carries it, along with MMO. My wrench has also indicated another product as an addative to the gas tank. It is called OPTI II. Apparently the Wing Riders are buying it up by the case.

Even after careful cleaning and "fitting" I had a couple GL1000 carb slides that hung up occasionally. MMO seemed to take care of that.

This is unscientific - but about three years ago I bought a used BMW R1100RT and it ran fine. I wanted to run some injector cleaner thru it and the shop didn't have the techron that I usually use - the guy talked me into sea foam (what a name!!). Anyway, within 100 miles the bike was running poorly. Did my own diagnostics and it was the o2 sensor. I've talked to 3 other owners that swear sea foam (maybe we used too much) killed their 02 sensors. Just info. Bob

I should have been more clear - in that instance I used the stuff in the FUEL tank

I always saw MMO on the little metal display racks at service stations since the 1950s along with all the other mechanic in a can or bottle additives, back then the oil was single weight and thick as molasses,I think Twisty has it correct as far as MMO is concerned {see below} I never used Sea Foam, because I have not seen it for sale around here if I find it I will try it because of so many good reviews on this forum about it. A lot of people have said using MMO made the shifting easier and the engine quieter. I would probably use the premium diesel oil instead of MMO. since the idea is to get rid of varnish and gum.

Twisty said "You could try an oil additive like "Sea Foam" or "Marvel Mystery Oil" but neither probably have the cleaning ability of a good (premium quality)diesel rated engine oil."

In the late 60's and 70's we use to put a quart or Pint of Diesel fuel in the gas tanks of V-8 cars to keep the Valves, etc clean plus it gave you better gas milage! Too much and it would smoke!

Farmers in the South did this for years with their gas tractors and trucks!

There were gas stations that sold a mix of gas and 3% diesel in the 70's!:clapper:

I pulled a good one with putting diesel in a chevy engine with very high miles on it, I put too much and the engine had too many miles on it, I poured some through the carb and added some to the fuel, I drove it about 100 miles and with all the carbon cleaned out it no longer had enough compression to start. So it is alike Brill-cream, a little dab will do you, on a really carboned up old engine. Havent used any diesel in a gasoline engine since....:goofygrin:

Can't say all that much about Seafoam, but MMO tastes better on both pancakes and rabbits.

Tried the MMO in the gas and saw a little improvement. Found the SeaFoam at O'Reilly Auto Parts and tried that in the gas and was really impressed. I saw far more improvements in throttle response, ease of starting and fuel mileage with the SeaFoam over the results I got with the MMO.

I did use 1 qt of MMO in my crankcase for 275 miles and I really feel that it did really well in there. I have read on here that SeaFoam works for this also.

I think, that when used as a "cleaner", SeaFoam is probably the bestwhen compared to MMO. It just seems to work a little better.

That's right, no one wants to admit to using miracle in a can when we should be doing the right thing that takes more work. I of course would never use either one, I just keep a can of each in the shop to remind me of the folly of using such junk.

Which one has more fiber?

I grew up helping my uncle around his auto service garage in the late 60's. He swore by a pint of ATF in each tank of gas, and often mixed a can of ATF in an oil change to clean the sludge out of cars not so well maintained. HE talked about the high amount of detergents in that ATF. He even WASHED HIS HANDS with the stuff at quitting time. Who knows?

I'm glad someone else posted about ATF (Automatic Transmission Fluid). Marvel Mystery Oil is really no mystery at all. It's a good grade of ATF. The previous post about ATF is correct. I have witnessed it work on an old Post Office Jeep (232 or 256 straight 6 AMC engine, I can't remember which one)with horribly stuck rings. An old timer saw me struggling with the vehicle and he took it for a couple days. When it came back it ran beautifully. All he did was drain ALL the oil and replace it with ATF and pour a couple quarts in the gas tank as well. After driving it for 50 or 100 miles he drained out the ATF and replaced it with oil. No more smoking, no more burning oil, no more gas contaminating the oil.
