So what is "pump gas" and what is "clear gas"? In my area we have about 4 main choices and they are listed in order of cost.Same, I’ve been running 91 “clear gas” for years. In all of my generators, saws, wood splitter, atv’s. When I spoke with my dealer about some issues I had while elk hunting. The first thing he asked was if I was running pump gas or clear. I said clear, and he said switch to pump for a couple tanks, and I bet the issue goes away. He said he’d even back by paying for the pump gas if it doesn’t work.
1. E85 - Not approved for our machines.
2. 89 octane which contains 10% ethanol.
3. 87 octane which contains no ethanol.
4. 91 octane which contains no ethanol.
89 octane with 10% ethanol is what is used by 90% of the vehicles in the area. Very few run the E85 even if their vehicle will run it. Not sure why anyone would use the 87 octane with no ethanol anymore, it used to be the same price as the ethanol version, but we live in farm country and the politicians changed that. 91 octane no ethanol for old vehicles, small motors and higher horsepower cars and trucks.
