It is now officially impossible to get straight gas here in New England. With all the hand wringing about fuel economy the do-gooders have succeded in forcing E10 on us...with the subsequent 3% loss in mileage! With the prospect of clogging the fuel system with disolved sludge and the damage to rubber bits throughout has anyone tried 100LL AVGAS in a M37? Any feedback would be appreciated.

I was on the phone with a New Englander, and he told me that the ethenol after sitting quite a while, it will draw water, and it all settles to the bottom of the tank.
He was cussing it quite badly.

Hmm, maybe that's why the darn thing won't stay running!

The M37B1 I bought had last run sometime in 2008 as it was inspected. The tank probably has 5 gals. water sitting under the fuel. Thats why I'm trying to get it started using fresh fuel out of my boats 6 gal tank. If you want to read my real feelings go to this link of a thread on E85, mine is the second post.

What about adding dry gas to the fuel whenever you buy a tankful? I use it in mine in the winter months, so far no problems.

THERE IS A STA BIL FOR MARINE USE THAT I DO USE IN MY PREFORMCE BOAT THAT HELP KEEP FULE FRESH AND KEEPS THE MOSTURE OUT, its called [marine sta bil]

Regarding 100LL, I use it in my M37, M151, golf cart, lawn mowers, etc., for the primary reason that it doesn't go stale. Never had a problem. My understanding is that it can be used in any engine that doesn't have a catylitic converter or an oxygen sensor. I'm certainly no expert on these matters, so I can't tell you if that is true, but it works for me.

I use it all the time. If your fuel system is in good working order it won't be a problem. If you have issues with your fuel system then you need to correct them. I do know I get less mileage with the ethanol as you stated but I can't tell any difference in the running of the truck.
