Does anyone know what E15 Gas is going to do to our LT1 Engines?

Biden ordered it today

 

I've been running non ethanol gas for as long as I can remember, so won't affect me currently. It's worth the extra cost. I don't put a lot of miles on my car so it takes a while to go thru a tank. Lots of benefits running it on non ethanol.

 

No one “ordered” the use of E15. No one will force you to use E15.

E15 has been available for years at about 2,300 gas stations, primarily in the mid-West and South. Until 2019, these stations were prohibited from selling E15 in summer months, due to environmental concerns. In 2019 an EPA rule change allowed E15 sales at those stations year round.

In 2021 a Federal court voided the EPA change, and restored the ban on E15 summer sales. Recently, this ban on summer sales was again lifted, to make lower cost fuels available at stations that were already selling it (but not in summer months).

Only vehicles sold before 2001 are at risk using E15. 4th Gen vehicles are designed for a maximum ethanol content of 10%.

 

Ethanol absorbs moisture so isn't good for fuel tanks, fuel filters, carburetors and i assume fuel injectors. If you drive your LT1 as little as me it's a real bad idea to use it. Letting it sit in your tank for extended periods of time is what I believe will lead to problems. I've always used premium gas and seek out gas stations that sell non ethanol. My only question is what if the guy in front of you used regular gas with ethanol and then you switch, how much is in the line and is it to much? I wonder if I should have my wife fill up a gallon or two in front of me of non ethanol to clear the lines. Especially just before winter when it sits so much.

 

Mrmint: good idea

Unfortunately, in NJ up until this year the only places selling ethanol-free gasoline were several airports, a marina, and a station that sold containers of VP Fuels ethanol-free. A local Sunoco station just added 100 octane ethanol-free. It's a good idea to use ethanol-free in infrequently used small engines like snow blowers, pressure washers, etc. Those things will gum up quickly between uses. when running E10.

 

In FL we have E15, and frankly I've noticed zero difference in how my Firehawk and SS perform when it switched to E10 in the summer months then back to E15 later...or just run on E15 year-round, period. Both cars sit a fair amount too, and get driven around 1k miles a year.

Now that I have my LT1 car back, once its running, maybe that will be a different story. The only ethanol free gas I've found around here is 89 octane, unfortunately.
