Gasoline Additives

When I was finished servicing the C-101 this morning I filled 2 six gallon gas cans at the local coop with ethanol free 91 octane and proceeded to mix up the witches brew I use as fuel in all my small engines. Each 6 gallon can gets 2 ounces of MMO, 2 ounces of STP Fuel Injector Cleaner and during mosquito season 2 ounces of castor oil. Does anyone else out there do this for their Horse fuel?

Wait, what is mmo for the uneducated such as my self?

MMO in my world means massive multiplayer online.

Marvels Mystery Oil. Really good stuff AJ. I would recommend putting it in your gas and oil. In my opinion its a LOT better than that sea foam crap. Last time I used that stuff I had to clean the carb in my snowblower because it crapped it up. MMO is WAY better.

Geno, many years ago I raced a 250 Bultaco flat tracker and always used Klotz castor based 2 cycle oil in it. A bunch of the old timers at that time swore that castor mist would stick to mosquito wings preventing them from flying. I've used it ever since (the smell reminds me of the flat track). Castor has a high flash point and passes through the combustion chamber pretty much intact and doesn't harm rubber in fuel lines and pumps as an added bonus.

AJ, sorry about the MMO abbreviation, it's what a lot of us old timers call Marvel Mystery Oil, a good upper cylinder and valve stem/guide lube.

What is the benefit if it is a "good upper cylinder and valve stem/guide lube". Why would one want that in the fuel/carburetor? Educate me or anyone else that may be lurking?

I personally think this is a great learning experience and may answer a bunch of questions for future use.

AJ here is the best explanation I can give. The upper cylinder is the area above the piston rings at any given portion of their travel and is therefore not lubricated when the piston moves up in the cylinder. Any part of the cylinder above the top ring is dry, that's why lubrication in the fuel is important. In the old days we had leaded gasoline and lead was a wonderful low friction lubricant but those days are gone (thank you EPA). The same is true for the valve stem and guide, there is no oil in the intake or exhaust area unless it's provided by the fuel. Hope some of this makes sense.

Makes perfect sense!! Thank you! I can now see why that would be very beneficial!

Major doesn't it clean the oil and carb, and also cleans up old oil in valve stems and guides?
