Got this sticker from a friend and put it on my car tonight.



Maybe this would be better for the humor section?  ;D

Did you install a jet engine in your car?  ;)

Avgas....similar to Mogas...

...for Piston Engines...

We used to run our Tiger Moths on 73 octane aviation spirit. My motorbike ran quite well on it too. Of course, you can't get it now. In those days 100 was called high-octane.

A lot of light aircraft are allowed to use Mogas which is the regular unleaded petrol you use in your car. At 95 octane this is a much higher rating than many of the older aircraft engines were originally designed for. It's also a lot cheaper than Avgas.

I thought I would dial up Mr Wikipedia for the "Octane Ratings of Petrol"...

.....he came up with this, over-the-top, description... ;)....>>>

The glider club's quad-cycle generally runs on 100LL, seems to like it.

True about "mogas", or unleaded hi-octane fuel, being suitable for many older aircraft engines, but in the US at least, three's so much doggone alcohol in it that it's unwise to use it. It can dry out seal and rubber fuel lines, etc over time, and it can also increase the chance of contamination, because alcohol in gasoline can actually hold water in suspension(?) in the fuel so it can't be detected by the usual sump-sample method. If your engine gets a swallow of fuel that's mostly water, it could stop on you... and not at a convenient time!

That being said, though- some pilots go thru the hassle of analyzing and treating mogas samples to eliminate the alcohol, or they'll just make sure they have a good mix of mogas and avgas, which seems to minimize the risks.
