Curtis73 (Forum Supporter) said:I would rather have "wet" E15 than wet E-zero. That's one of the best parts about ethanol for marine applications. Quick math... if you have a 40 gallon fuel tank full of E15, it can suspend about a half cup of water. Straight gas holds next to zero.
Any E0 that goes in gets a light dose of Iso-heet for exactly that reason. Accumulated water in fuel tanks is bad.
Sorta related, but are there any more unanswered questions about ethanol fuel that can be tackled in a future Fuel Tips item? We have our friends at Sunoco on speed dial.
Yes, over use in 2 strokes.
I'm a big ethanol fan. Defend it constantly. However my understanding is that it destroys lubrication properties of fuel and oil. This makes fuel dilution in oil on (turbo)DI cars a concern(no long change intervals), and obviously a piston searing no go for 2 strokes.
The only time I've recommended against e gas is 2 strokes. I also think it's an underlying cause of the Renesis apex seal failures(very 2 strokey, older rotary's were pre e gas). Curious if I'm wrong/out of line with that thinking.
In reply to ztnedman1 :
Let me see what our scientist friend can tell us about that.
