Default Re: Regular v premium

Living in the Tropics, where it's above 90 % humidity probably 1/2 the year, gets me a bit skeptical of fuels with higher ethanol content, I forgot to mention the water absorption thing. Cheers Dave.
Your right about rejetting for alcohol, and I guess it could lead to a lean condition also on a Two stroke that was tuned for regular gas?
In which case may seem like a little more power if you were originally running a little rich.
Don't know how/why, but our fuels seem to have higher ratings than yours, but we pay 4 times? the price for it.
Ethanol is also used as a 'filler' here, but I remember reading somewhere that our 'Premium' (95/98) is boosted with ethanol?
