If you see nothing then it is probably OK. 100LL drys without leaving a mark, a ring around the spot could mean jet fuel, or diesel fuel is in it. BTW the last time i was in Hawaii, I seam to remember the fuel to be red because the only fuel they can get is 120-130 octane.

2020年6月30日 · Switching tanks always introduces some small element of risk (e.g. failed fuel selector) and changes what is currently a properly functioning fuel source.

As I walk my neighborhood most of us have 500 gallon fuel tanks for avgas and with the price of fuel most of us don’t fly as much as we used to. I have no doubt there are tanks (vented) with 3-4 year old fuel and guys are burning it without problems.

2016年1月8日 · 100 octane aviation fuel is not rated the same as fuel for cars. The aviation fuel uses a performance type octane rating system (remember red, green and purple aviation fuels?) while cars use the old R+M divided by 2, that is Research method of rating octane plus the Motor method of rating octane, then divide that answer by 2 to get the octane ...

G100UL or its equivalent is the only widely practical solution to removing lead from aviation fuel.
