Seems like it has been a long time since I first started seeing the up to 10% ethanol signs on gas pumps...

The other day I found a new gas station proclaiming Ethanol Free Gas! for about what I pay for Shell.

Any GOOD reasons to start using it (again) other than fuel economy?

 

Technical reasons? No.

Political protest? Absolutely, sign me up.

 

Excellent.
Glad to see it reappearing.
Just make sure it has proper octane.

Out here the only ethanol free is 85 regular. Not good enough for our Jags.

 

+1

Gas is for vehicles, corn is for feeding people.

 

Here is a good primer on gasoline blends: The Oil Drum | Refining 101: Summer Gasoline and The Oil Drum | The Switch to Winter Gasoline and a Primer on Gasoline Blends

 

Excellent stuff.
Head spinning but ok!

 

So the PO of my recent acquisition only used regular (87) gas in this poor thing. In reading these posts, I see it needs a steady diet of the best premium gas available. I am repenting immediately! Two questions:

1. Is the low octane gas in some way linked to the "Restricted Performance" DIC messages I get occasionally?
2. Is the 2001 4.0 engine immune to the effects of ethanol in general or should I be protecting the rubber seals, etc with ethanol treatment?

Thanks

 

- I use NE gas in anything that sits (mowers, chainsaws, trimmers, motorcycles, etc)
- With everything else even, you will get about 5% better gas mileage with NE gas: Alcohol has about half the enthalpy (inherent hear energy) of gasoline. Therefore, 10% eth gas has about 95% of the energy of 100% NE gas
- Around here, NE gas is much more expensive
- IMHO, Absolutely no reason these days in USA to have eth gas, other than as a subsidy to corn agribusiness (and, eth production is a v dirty industry, pollution wise, IRRC)

 

That so far is my only complaint about old Trump, he said they could up it to 15% alcohol.
Not a good thing at all, for us or our motorcycles,& cars.
