Re: Marvel mystery oil
I have "heard" 4oz/10gal is the correct mixture. I also "heard" it should be added before just before the gas is added to the tank in order to mix it. MMO poured into a full tank will settle to the bottom without mixing.

It'd be cheaper to add 4 oz of jet-A and a drop of Adams red food coloring, but unfortunately we all know that contaminating our fuel with things other than avgas is a no-no.

Re: Marvel mystery oil
I refuse to deal with alcohol in small engines, I use 100LL exclusively in all of them. It won"t turn bad in a couple of months and never cruds-up your carb. And I run small engines hard enough that the lead isn't a problem either.

I've been running 100LL in my lawn mower at the airport for 3 years now. Never a fouled plug or stuck valve.

Re: Marvel mystery oil
Yep, I've had the same experience with all my small engines for the past 25 years or so, no problems.
Somebody must have used a Briggs and Stratton engine in an airplane somewhere down the road. I have never had a problem with one until they have been completely worn out and then they just start smoking and give you plenty of warning before they quit. What was the biggest one they made? I can't remember. Might have to put 6 or 8 of them down the wing to get enough power, like a miniature Spruce Goose.
If we ran our airplanes at full throttle all the time, they probably wouldn't foul plugs or stick valves either.

Re: Marvel mystery oil
Well, not except during takeoff and climb. Maybe I should try it, the Airplane Flight Manual says it's ok.
Reminds me of when I got my first Super Cub. I asked a grizzly old Alaska bush pilot how he ran his Cub. His answer was, "Give it full throttle for takeoff and every once in awhile reach over and tap on it to make sure it hasn't "slip back" any"! Funny thing but he always got full TBO out of his engines.

Re: Marvel mystery oil
Northern Tool here in the DFW area must be dumping their MMO on the market this month...it usually sells for about $7 to $9 for a pint ...but I just bought a gallon of it from them for $11.
Too bad I don't have a use for it.
