We recently did a trip to Colorado and purchased MOGAS when possible.  Most of the MOGAS available at airports was 87 not 91.  We are flying a Europa with a 914.  Since we usually operate at 70% power and only use 100% for takeoff (have never used 115% except for ground testing), is it OK to use the lower octane MOGAS?

Jim,



I'm by no means an expert on fuel, however I would have no reservations about using 87 instead of 91 OCT as long as I had enough OCTANE Boost (plastic bottle) found at NAPA, Advance and O'Reilly Auto Parts stores....

Hi Jim & Heather,

I operate my 914 much the same as you. It is my understanding that running lower than 91 octane would be risky. You can mix 50/50, 87 Mogas with 100 LL.

I have looked in to octane boosters from auto parts stores, but most of them are alcohol based and I don't want to increase the alcohol.

I travel with a 5 gallon gas container and use that if I can borrow the "crew car", and even have taken my long ranger tank in to town for car gas and lunch on trips.

Hi Jim,



Absolutely do not use straight 87 oct. You can use up to a 50/50 mix of 87 and 100LL. No less then 50% 100LL. You can use less 87, but not less 100LL. Detonation can happen before you have any warning and then you just cost yourself a minimum or $4500+.  If you only use the 100LL once in a great while when traveling then don't worry about it and use the 91 oct all other times at your home field where most owners spend the majority of the flying time. If you are using 100LL then use a lead scavenger like Decalin. It is 1/2 oz. per 10 gal. You can pick it up from Aircraft Spruce for about $20

Roger,



What are your thoughts/concerns/comments regarding the use of Octane Booster in the Rotax engines (2-stroke and 4-strokers)?



Would like to hear your 'professional opinion' ....



Thanks for your time.

Its not about the cost its about getting what you want. If airports would provide 91 octane unleaded fuel I would pay whatever price they wanted even if it was more than the 100LL.  I always make that clear to the FBO when I take their courtesy car into town to fill up my gas cans.

It's not so much about saving$. It's about not not using leaded fuel.

But your right, I am a cheap SOB!

Kevin,



Thanks for sharing your experience.



Do you have a 5 gal can that folds down when empty?    I haven't found one and really don't have the space to carry a hard plastic can.



Probably won't do Oshkosh even though it's only an hour away.  Just too hot and too expensive.

I  have two of these, they work great.  A little pricey but well worth it when you go to use it.

Are they resistant to gasoline, at least for short periods - so you can go to station, fill them and empty them into plane?

Jim,

I do not have a "soft" gas container. I saw some once, I think they were called turtlepacs or something.

It's sad that we can't get 91 unleaded commonly at airports. I'm trying plan the flight to KOSH from CA without using 100LL.

Not sure it can be done without driving to town for car gas.

Kevin

Yes, They are made for Gasoline and are very durable.  When empty they are only about 1/4 inch thick and will lay flat in your baggage area.  They are about 2 ft X 2ft square with really nice handles to carry it and to pour into the tank.  There is also a spout that threads onto the end.  The bag will lay on top of the wing while the fuel drains in.  Much easier than a rigid gas can.

Hi Joel,

I was wondering if you have any problems with the the bags swelling up the residual gasoline left after you have empty them into the airplane gas tanks and put them away in the back of the airplane.

They have never swelled up.  There isn't much if any residual gas that remains.
