Oh no, the plastic gas lines in my car that are twenty years old should've been destroyed by now from all of the ethanol. Wait a minute, there not, I would have thought anything ethanol touched would have been destroyed by now, but its still there.gas without varnishes, gas with destroys
Occasionally I'll put Aussie 95 in my Vegas,I'm in Australia and run unleaded 95 octane.
Yeah my 10 Vegas seems best on mid grade here,My 12 KP seems to like mid grade best.
I've been running 90 octane, ethanol free, as often as I can. Anytime I can't get to an ethanol free pump, i run 89. 6 years of running the Freedom Vtwin and 89 octane has never caused a problem.I'm telling ya, go into a marina if you can and fill up there, last time I did that my truck said I had over 440 miles to empty and the other places I go to on a good day with a fresh truck load I may get around 395-405 miles to empty.
My own math confirms this too, I always get better mileage out of the marina 89 octane fuel, my truck seems to like 89 the most. I am not sure if you can get 87 at the pumps at most marinas.
