Thread: Fuel for your 912?

What fuel do you use in your CT?

100LL. Mogas where I can find it. ADS prohibits self-fueling from cans.

I use 91 octane mogas when at home base, but necessarily use 100LL when traveling, which makes up most of my flight time.

I have a hand cranked 30 gallon gas caddy which I put in bed of pickup when going flying, fill to predicted need at the local station, and take to the airport. This does require an assistant for crank turning, which turns out to be about 15 turns per gallon. (Or, just for a short flight, might just take a gas can or two.) I fuel through a Mr. Filter funnel to capture debris or water.

For info, I called the official who inspects fuel in gas stations throughout Utah and he says that our motor fuel will have no MTBE or Ethanol or anything else as additives in Utah.

Most of my flights are less than 4 1/2 hours round trip so I almost always fuel at home. The 13gph pump means less than 2 minutes per wing. Chevron in California limits Ethanal to 5.7%.

Looks like a great setup....in Oregon we can't pump our own gas at the gas station!! Curious because the tank is no DOT approved if they'd refuse to put fuel in it or not. Guess I'll have to ask - or move!!!

My lease at ADS says I can have two 5-gallon cans of gas. If I could find mogas without ethanol I'd use it, but I don't trust the gas stations to be truthful about ethanol content.

Don't they mix the ethanol in when the underground tanks are filled? If so, then the stuff coming right off the truck is what you want.

MoGas gets mixed at the terminals. Additives are normally blended there - this allows for quick changes due to seasons (vapor pressure changes).

I'll check my lease at ADS, but while it does allow for MoGas cans, I don't think it allows refueling aircraft - go figure.

Ok, I have a question that relates to this topic, I think... My ONLY gas station in Lubbock that stocked 100% ethanol free 93 octane premium was the Chevron dealer. I went by there tonight and they've now lowered it to 90 for premium. The entire town of Lubbock now has only 90 octane or less!!! I can travel 50 miles in either direction and they stock 93, but not here. Probably something do with supply and demand. Now, what do I do? I know the Shell stations have NO ethanol in their premium and I got that straight from a tanker guy that was downloading fuel as we talked. He said to try an octane booster that could kick it up a notch. What do you guys think? I'm using the Shell sport 4 oil so I can go with avgas if I had to but with 25hr oil changes. I just bought this trailer, tank and pump rig for around $1400 and now I can't even use it! First, the oil changing dilema and now, the fuel. Just a few little things that I'll get worked out over time. Wouldn't the octane booster do the trick?

6- 5 gal tanks with mogas. Except on cross countrys, then 100LL or when flying over 10,000 msl. It would be nice to have fancy fuel cart like some of you have but unfortunatly not in the budget. Good thing Im still young

I don't know anything about the octane boosters. If all you can get is 90 octane, and you find that the octane booster is not the way to go, I would mix a small amount of 100LL with the 90 to bring it up. It shouldn't take much to get to the required 91 octane but I don't know how much.
