Mogas and a "no fly" winter
Because of personal schedules, and circumstances at the airport, we won't be able to fly the 170 until May (hangared). The tanks are full of mogas, with a small percentage of 100LL. What are our options to ensure the fuel will be OK in May?
I did a search and found sta-bil may not be a good idea.

Drain the fuel into a container (thru the gascolator may be the easiest method) and use it in your tractor, etc. Fill the aircraft with avgas. (Not being didactic. Only giving what I truly believe to be the best advice.)

Ya, I knew the right thing wouldn't be the easiest thing to do. There is a slight chance to fly off some of the mogas in a week or so. The town hasn't been keeping up with the snow plowing at the airport.gahorn wrote:Drain the fuel into a container (thru the gascolator may be the easiest method) and use it in your tractor, etc. Fill the aircraft with avgas.

Thanks for making me look up the word "didactic".
Re: Mogas and a "no fly" winter
I know everybody wants to be safe and I don't want to sound like I'm a careless person. I have used car gas exclusively for 30+ years without ANY problem what so ever. I am still getting alcohol free car gas now. I buy it in bulk and sometimes it has taken me more than a year to use it up before getting another load. I do not have my 170 on skis and it is now sitting in the back of the hanger behind my supercub which is on skis. The 170 is full of car gas and when the snow is gone I will have NO qualms about firing it up and flying it this spring. I do check things out and so far I have never found any water or contaminates in the strainers or the carb. Both planes start better on car gas (winter and summer) and run better (no bad mag checks or plug fouling). I guess what I'm trying to say is I'm tired of people always bad mouthing car gas. If you don't want to use it, fine. As far as I'm concerned as long as it's alcohol free it is better for these 80 oct. engines than avgas that has 4 times the lead than these engines were certified for. If I were you I wouldn't worry about the gas in the tanks sitting over the winter. Just my humble opinion.

Where do you find alcohol free mogas?
Re: Mogas and a "no fly" winter
ginbug92b,
Right on ! I've used mogas for years and have never had any problem with it going bad within a year. Even with it containing 5% alcohol here in California.

Re: Mogas and a "no fly" winter
Mogas will go bad sooner than 100LL, BUT, it will go bad much slower the colder it is. I would worry more about the plane sitting thru a hot summer than a cold winter. I used it exclusively for 10 years back in the leaded regular days and never had any problems. George is correct though, if you want to ensure everything will be ok in the spring, drain or use the mogas and refill with 100LL for storage.

Re: Mogas and a "no fly" winter
Was talking to my Nephews father in law in California. He delivers gas to service stations and farmers bulk tanks, and if I understood him right the California gas is so bad that if it is not used up in about a week cars will not run on it. Says it gets milky looking and he has to pump the tanks out and take it back to the plant to be cleaned up. I may want to move a old truck and then let it sit for a year or so down there and am wondering if a excess of water was added to the gas would it pull out the alcohol to where it could be drained off? Any bright ideas?

The real shame is that California thinks it's so special that it deserves its own blend of gas.blueldr wrote:It sure is a shame there are no airplanes in South Dakota.

Certain areas of Texas (all of them rural) still receive auto gas sans ethanol. I consider it safe enough to use in my lawn mower.

Re: Mogas and a "no fly" winter
As I peruse this thred I can not prevaricate, and I concur with George's disquisition ..............ie burn it in the tractor. I burn 87 oct car gas all the time in my airplane. I do get it fresh often. I do have a 300 gal barrel on the farm that I use in my gas tractor and even though it will sit all winter and come spring the tractor fires right up and I use the rest of the barrel, I don't think I would put that in my plane.gahorn wrote:Drain the fuel into a container (thru the gascolator may be the easiest method) and use it in your tractor, etc. Fill the aircraft with avgas.

I just had to have alittle fun with George.......
