I tow this behind the car and buy 50 gallons at a time. It holds 109 gallons. Flocker gave me the idea. That’s quite a rig! I fill mine up to the brim about every 2 months and have never had a shelf-life issue.  |

It’s important to store gas in a metal container. A chemical engineer told me that plastic gas cans might as well be window screens when it comes to containing fuel additives and keeping moisture out.
It’s true Avgas stores better long term but properly stored Mogas will be good for several months.

For those using mogas who don't have pickup trucks, how are you transporting your fuel? I happen to live in an area with no on-airport mogas options within a reasonable distance. So my only option would be guying at a gas station and ferrying it to the plane. As I understand it, transporting any significant quantity of gas in an enclosed area such as a car trunk is dangerous--a really bad idea. Inside the car is better but still not great. Windows rolled down and containers secured tight in the back seat would help. In the end, I keep buying 100LL and Decalin, though I would prefer not to. It's almost like a pickup should be included with every Tecnam purchase.... I have several high quality 5 gallon containers that I use to transport fuel. Typically fill up 3 or 4 at Costco on the way to the airport. i try not to store fuel in the containers for any length of time, but will keep in my hangar rather than in my garage at home. Definitely not in my SUV. |

Got to ask...for those of you who trailer fuel, what are your state laws for transporting fuel? In NY, it’s a No No!

Rotax says 91 minimum so use the 93. I have close to 900hrs on my P2008 with 914 engine. Over six hundred have been with 93 with 10%e. No problems Ed Are you the only pilot? Renting or leaseback? What issues have you had with repairs or non-routine maintenance. What year is your P2008? I have been told that MOGAS is better for the engine vs AVGAS 100. T/F |

Hey, I built one of these a few years ago too! I was warned by a FBO that fills a 200 gal tank weekly that one must be very careful about moisture if you keep the gas in tank for extended periods of time. Not my personal experience. Just asking if anyone has seen this problem with storing larger tanks of MOGAS that comes from a local filling station. |

Mogas is better for Rotax engines. Don’t store it more than a couple of months and use metal containers.

In the tank I pictured above, we add 1oz./10gal 'Sta-Bil 360 Marine'. Not only does that stabilize the fuel (although our 100 gallon tank doesn't last long), but it treats for ethanol and moisture. When pumped, the fuel is filtered by a cartridge 'Hydrosorb' filter for water and particulate. I think we're covered.

The debate over 100LL vs mogas will go on forever. In a perfect world mogas is the first choice but it has a few negatives. It will gum up your carburetors if it sits too long without use (a serious safety issue) and is clearly more susceptible to vapor lock.(another serious safety issue)
I don't like the stains it leaves by the fuel tank vents and the smell if I spill a little either.
100LL definitely gunks up the engine with lead but according Rob Seaton who has likely overhauled more rotax 9 series engines than anyone the life of the engine is negligible if you use a lead dispersant like Decalin.
Personally I use mogas if its convenient, I know its fresh, it not hot out and the plane will not be sitting long with mogas in it.
Otherwise I have no problem using 100LL and Decalin.
