What fuel

Jacques
I use any premium as long as the station had not just had a fuel shippment, no additives

93 or better in all my toys

 

And all of us in the US are getting our 10% ethanol like it or not. I knew one station in upstate NY that had non-ethanol gas last year but no more this year. I hear from my local Exxon station some refineries are going up to 12 or 14% as it is cheaper for them to blend.

I upped my CO reading a bit this year to compensate. Reading spark plus is no longer relevant; they always look chalky white.

Why is this?

 

to what Ken?

I bumped it up from maybe 1.3 to 1.9% as close as meter will read. Not a big change but I felt more comfortable that way. I think you are running over 2% last I remember.

All the water and muck is stirred up every deliver and sold as fuel.
I know stations that never pumped the water out of their tanks just sell it with the fuel.
There is a reason you have fuel filters on cars.

 

Ken the last time I checked I was running around 2%. Maybe just a tad more, but not much more.

Every "toy" I own runs rich rather than lean. Running lean means you have to watch temps and valves; running rich means you get some unburned fuel in pipes, some soot on the rear panel, and maybe a bit of fuel in the oil. Considering I change my oil every 2,000 miles and every spring and fall, regardless of when it was last changed, I don't worry much about fuel in the oil. (changing the oil in cars is therapy for me so if I change it twice in a week it is still cheap therapy for the soul)

In Texas once you're over 25 years you still have to pass a safety inspection but no more "tail pipe sniffing" so I don't worry much about the 2+%.
