That will work well with both MPG and power, but in the end it won't have the cooling effect of the ethanol (which is minimal in E10 but quite a bit in E50+).
2017 CS / GT Premium, all stock with exception of opening up the air intake they the grill (radically lowered my intake air temp), and added a K&M drop in OEM A/F. Ethanol Free "Puregas" available locally is 89, can get 20 about 20 miles away. When I use RFF and OB, my mpgs get slightly better. My concern is that the Eth in fuel at the pump (I have heard) is not pure (99+%) alcohol, but can be as high as 20% water. Is this true ? Also, have heard about people adding O2 injection at the intake, to get a more volatile, and cooler air component in the A/F ratio. Any truth to this ?
try marine supply pumps. If you're >50 miles from DC you can possibly find Ethanol-free stations, typically only 87 though. eg. several in Winchester VA and some southwest of Fredericksburg.
Yeah, this being a big boating area, there's a ton of ethanol free pumps at gas stations.
+1. Never had an issue starting up after a half season of sitting.
Yeah, that's what I did, the couple of times we've needed the generator, we ran it totally out of gas before putting it away. Lasted a long time, so I guess that worked well enough.
