4 cyl Silverado gets worse mileage than the V8

[FoMoJo]

Why would/does anyone ever use E85?  Less power, worse mileage, and more expensive(?).......lose-lose-lose.

Farmers.

Same.

Less expensive.per gallon, at least here in California. No real advantage, though. It's about the same cost per mile.

More renewable is pretty much the only advantage, I think.

farmer subsidies

More expensive cooking oil.

That explains why it's produced. That doesn't explain why it's purchased.

Biodiesel!

[shp4man]

Depending on oil prices, there can be an advantage to E85 in fuel costs. Right now, gas is pretty cheap.
But California is currently switching to summer blend fuel, which is typically 12-14 cents higher per gallon.
So I may be going back to E85.

Ha, my '88 GMC gets 13 (on a good day)!.

It's cheaper in Nebraska I believe.

Back in 200(6?) when gas prices spiked stupid high, E85 actually was far far cheaper than regular unleaded.

Race cars can use it.  Moar bewst.

Fair enough, that's why I put the "?" 'cause I wasn't sure how it compared price-wise.  Nobody here has E85 so I never see prices.

With proper tuning, you can actually make a lot more power with e85

If you have large enough injectors.

But what car has an E85 tuning? The Koenigseggs do, but other then that?

[shp4man]

My Focus is a kind of rare SFE model. It's flex fuel capable and tuned for fuel economy, as apposed to the other sedans that are PZEV vehicles, tuned for low emissions.
The FSE has rear disc brakes, 16 inch wheels and extra air dams underneath to give it better coefficient of drag on the freeway.
Ok, so it's not that big of a deal, but, you know...

I know. My Fiesta is also a kidn of rare SFE model. But it's not flex fuel, it doesn't have rear disc, it doesn't have special air dams or under body panels, and it came with steelies.

I think it stands for Super Fuel Economy.

I thought it meant Sometimes Fuel Efficient.

But you burn way more of it. Like it might be 10% cheaper, but you burn 20% more of it.

Only people I know who are into it are internet dyno hoes who like to brag about having E85 tunes.

My friend's car make 40AWHP more on E85, and that's very noticeable vs 265AWHP on 93

E85 eats up certain kind of rubber though, so the motor had to be built for it.

Mostly the fuel system.

The 10% ethanol that most gas is now also plays hell with a lot of older cars.

Anything carbureted with a mechanical fuel pump at altitude has a very rough time with warm temperature.

What's high altitude?

My car does fine. I have an Edelbrock, though. A Holley or other carb design with gaskets below the fuel level might struggle more.
