E15 in Etec?

**doug7488** · 05-27-2022, 11:29 AM

I heard that the local gas stations will be switching from E10 to E15 soon
Can I safely run my Etecs (300 G2 / 115) on it?
thanks!

Nope

I don't think all stations will carry only E15, at least not in our area. Some will be available but I don't think any outboard mfg has approved E15. If E15 was my only choice I would simply continue with the non ethanol I currently use.

Yeah you shouldn't really even be running e10 in your etec now. Those and optimaxs don't do well with ethanol. Burns too hot and the engines are too lean

Unfortunately, aside from buying race or aviation fuel, I don’t believe that there’s an alternative in the tri-state area
I asked at a few marinas about the upcoming E-15 fuel
They had no information
I think that E-10 has been the only choice around here for the last 15 years or so

You can add some opti oil premix to the fuel it will help!!

there is not an engine manufacturer out there currently that authorizes anything more than e10 in their engines. Any more than that, and they will not honor the engine warranty if that is found to be the cause of a problem. I would think that if the the manufacturers wont stand behind their engines with that fuel, it would be a bad idea to run it.
