Better to look like a ignoramus asking ridiculous questions, than have a stinking airplane with an engine that won't run. I posted the issues here, 'cause I thought there might be at least one or two who've flown with mogas a few times 8*) I keep hearing nebulous concerns about mixing mogas with composite tanks like the Delta has (alcohol will attack the epoxy, etc), but it doesn't seem like anyone has any solid data. Just innuendo. That is why I was talking with an epoxy expert. I appreciate Perry's data point and 5yrs of experience. Perry, what epoxy did you use for the tanks, and do you take any special precautions when fueling up? The other two 'issues' were out of the blue. The Cherokee I trained in used mogas. I never noted excessive smell, and my flight instructor said it kept his plugs clean. The issue with stale gas has some credence due to my observation of some ultralighter who religiously dump 30day old two-stroke mixes. What I didn't get was how 100LL smelled any better or stored any longer. Both issues appear to be red herrings.
