Old LL100?

Is there a way to test or safely utilize 30 gallons of 8 year old LL100 drained from a non flying RV?

Use it in your riding lawnmower or make a friend with a classic car really happy.

Old AvGas

The fuel supplier for our airport requires that fuel in storage tanks must be used (or added to) at a maximum of nine months intervals. They go through about a semi-trailer load per month so its not an issue. It is tested for water, particulates and API gravity often. I wouldn't use 8 year old Avgas in an airplane, period! Find the cheapest chainsaw, leaf blower, mower or similar you have to dispose of it through. I wouldn't even run it in a hot rod or dune buggy if it was that old.

We found that in the artic old fuel burns better than no fuel and I have reluctantly used fuel (from sealed drums, stored on their sides) that old and noticed no ill effects. I am not advising you to do that - just saying.
