Need gas fuel help!!!

[Jeffrey Hammond]

I need some recommendations for fuel for my Zenoah 260 PUM on my thunderboat. Nooby here. Do I take one gallon of 93 octane non-alcohol fuel and add 2 stroke oil? How much oil do I add to a gallon of gas?

 

[Dave Gilles]

standard 87 octane + 8oz of klotz super techniplate. your zenoah is basically a 2 stroke lawn mower engine. It doesnt care what you throw in it.

93 octane will make is slower.

I take 1 gallon Coleman or Crown camp light fuel and add 10 ounces of Red Line 2 stroke oil.
No nasty smell in the car

But my oil is Mercury O/B synthetic oil.

Any good 2 cycle oil and mix it at the OIL manufacturers recommendations. what ever the bottle tells you to.

after all it is a chain saw/weed eater motor.

A lot of testing has been done. For our engines 8-10 oz per gallon is the norm. I personally run 10 oz to 100 oz of fuel. Regular non ethanol unleaded or camp fuel. Running what the oil manufacturer says will burn up parts. Cylinder seal will increase with more oil. Then it becomes a matter of keeping the rod bearing alive. We are stressing these things way beyond design limits.

Guys
This is all great info!! I have also been reading on the Klotz site and does anyone run R50?
Sounds like Coleman fuel is the best choice on the gas side……at least the least stinky, buy it in a can, few additives, etc. also very expensive, but if you don’t run much, it doesn’t really matter.

50% Coleman camp fuel, 50% 110 octane low lead aviation gas and 8oz. of a good quality oil per gallon. Rock solid performance and no smell. If it's a new motor don't run synthetic oil until you've put at least 2 gallons of fuel thru the it.

I was thinking the aviation gas has no smell, right?

We did some serious fuel testing. See below:

That’s some great information, and thanks for the heads up on the new engine/synthetic oil thing. My engine is, in fact, brand new, so I need to find the correct oil. Suggestions?

Well...... if you stick your nose right over the can it does but won't stink up your shop or your vehicle.

I used to run Klotz and Quicksilver but there was a lot of carbon buildup on the piston. I changed over to Amsoil Dominator and no carbon. Clean as a whistle

cause it flashes at a much lower temperature. if you're not burning off castor blends you're too rich or not running hard enough to get the heat needed to flash it.
