Fuel additive

[BigErn]

My bus has a 366 towanda,it has 196000 miles on it,doesn't have any leaks, doesn't smoke,doesn't burn any oil so far.Just wondering with this many miles on it.
Do any of you use a fuel or oil additives?
I bought it to make a bunkhouse for the deer lease.Going to put toilet,shower and bunks,so it won't get driven really all that much.
Thanks for the help! Ernie

Nice short bus Ernie.

Prior to the official answers I'll give you the farmer's answer. I was taught to use transmission fluid in the fuel to clean the injectors. In cars about a pint added to the gas every three months keeps your carb or injectors clean. There is reportedly lots of detergent in tranny fluid, even more than the injector cleaner additives.

Newbs to this injector cleaner method often have doubts, but it works well. Gas or diesel.

As far as the oil, I'd guess what oil you use depends on where you spend the winters. I have also seen people use tranny fluid to clean the oil system in old cars, but be aware it can release all the gunk and plug your oil filter on really dirty engines. This is usually done by adding a quart to the oil when the engine is already warm and running. Run for 5 minutes with the tranny fluid then drain. Do not drive it while cleaning the oil system.

Am I pretty far off track?

I would also put in the marine version of Sta-Bil or equivalent when you park your bus.

The ethanol blended fuels are about as bad as anything can be in a fuel system.

It is hydroscopic (attracts water) and the chemicals that keep the ethanol suspended tends to keep the water suspended as well.

In addition, the shelf life of pump gas with ethanol blended in it is about 30-days.

Without some sort of stabilizer it isn't going to be a question of if you are going to have fuel system issues as when you are going to have fuel system issues.

My preference for fuel additives is made by PRI (Petroleum Research Institute)
They make a PRI D for Diesel that can keep diesel fuel at near refinery fresh for up
to ten years. The PRI G is for gas and can keep gas usable for up to ten years as
well. Prefer it over anything Sta-bil can put out.

I don't use anything consistently. If it's diesel we'll add powerservice diesel fuel supplement for an antigel. I also know guys that will use ashless 2 stroke oil in them because the ultra low sulphur process takes away some of the fuel lubricity.

I don't use engine oil treatments, because I use good engine oil and change it when it's time.

I don't usually use fuel treatments on gas engines either, because I've never really had problems that made it necessary.

ATF does have a large amount of detergents in it. I have added a quart or two in place of oil on some of the more gummed up engines. I've also used it to clean deposits off intake manifolds and valves without engine disassembly. I've never used it in fuel though because I've never had or felt the need.
