E15 gas

Yep

 

Yes.. With ethanol

 

Always.

 

Hey i've run an old iron duke kohler powered garden tractor since the early 70's made to run on non ethanol gas, yet its run on everything from fuels containing mtbe to e10 ethanol, and its still running never apart.

 

Are you sure your gas cap accepts up to E20?

The caps I've seen have a ban symbol for that fuel.

 

Revived idea from the 1970s under Jimmy Carter. Back then it was called gasohol. Gas stations would have a single pump dedicated to it. The people who tried often ended up in the shop with fuel system related problems. It quickly disappeared once it started getting a bad name. MTBE gasoline was introduced to replace leaded gasoline. That was due to emissions as the lead would destroy catalytic converters by coating the catalyst making it ineffective and clogging it. That too caused a few problems as engines designed for leaded gasoline didn't perform well as the lead was used to lubricate parts of the fuel system, if I remember correctly. MTBE gasoline was known as unleaded back in the 70s and 80s.

 

We all may have no choice but to run e15 if gas prices continue to rise. From what i gather its suppose to be cheaper....on the other hand you get poorer fuel economy that their not telling us.

 

Read your cap

 

It's not harsh to current materials. I've ran e85 in vehicles for 20 years.

 

The ecu pulls timing based off detonation, not ethanol content and why it's safe to run any octane fuel.

 

That's an issue with higher % ethonal like e70.

 

ethanol free isn't hard to find around my area, its just expensive af and most people just use it in boats.

 

We've had e10 grade fuels since they eliminated mtbe in the gas decades ago. I can get better fuel economy when i'm up in vermont using their ethanol free gas, so i can guess what e15 will be like. As far as any other issues with our current e10 fuels...there haven't been any.

 

E10 was a big issue for folks that I knew on the motorcycle and marine side. Lots of deformed tanks or trashed fuel systems. Yes. The products should have been designed better, but . . .

In the end, I would still favor E0 any day of the week. Ethanol production, transportation, lower energy, and damage are way worse than E0.

 

Yep, using e10 i had to replaced the fuel pump in my older 15 hp outboard with one of newer components resistant to ethanol, the pickup in the outboards fuel tank rotted off due to ethanol. As far as my 2 stroke dirt bikes i raced, the engines were all built to run B32 phillips race gas at the time. Even 100ll av gas worked decent, but required different jetting.

 

I'm more concerned about MMT. According to the EPA a little is fine.

https://www.epa.gov/gasoline-standa...ricarbonyl (MMT) is,gallon manganese (gpg Mn).

I'm skeptical that the EPA knows better than the vehicle manufacturer.

Toyota does not recommend the use of gasoline that contains MMT. If fuel
containing MMT is used, your emission control system may be adversely
affected.

 

Was an issue pre e10. I've ran e85 in early 90s cars without issue. It's like race fuel and run it in my turbo and high performance cars. Love the stuff.
