E85 Fuel

Just a question to you all that have Class C Chevies. I have read via GM that the Chevy 4500 Express is Flex-fuel. Based on this and having an Onan generate in my 2013 2860,..soon to be picked 05 Jan, one would think that you cannot use E85 since the genset is probably gas only. Just need to confirm this before I drive it from Des Moines to Colorado Springs. I would think that the dealer will tell me this but just in case they forget and I also do.

Thanks

I've never considered using E85.
Isn't there a BIG decrease in power and MPG with E85?

Why use E85 when your mileage will suffer, your performance will suffer, and your generator will suffer as it is not designed to use E85.
Stick with the regular stuff.

From what I have seen e85 seems to be about 20% cheaper.

On e85 vehicles you have stainless steel lines, different fuel pumps and seals and gaskets will differ. E85 is much more corosive and will eat up normal steel lines and rubber lines too.

Don't know if generators are making the switch yet, should be intresting to find out. Here in OK its hard to find stations that even sell E85.

Thanks guys,
Just trying to compare the tradeoffs with E85. Here in Colorado we have E85 at many stations.

You don't think think the gen. will be propane do you? That may be how they could get around the e85.

Just thinkin outloud- most of the time gets me in trouble

If you use e 85 even if the engine is made for it you are asking for trouble. The stuff is pure junk for your engine. It's a waste of money and you mpgs go down. Don't bother.

You can get an idea of the fuel mileage decrease using E85 from the EPA fuel economy report.
http://www.fueleconomy.gov/feg/pdfs/guides/FEG2012.pdf
As an example:
F150 Pickup 2WD FFV
5.0L, 8cyl 15/21
11/15 on E85
I assume they used pure gasoline for the test, not E10 which is sold most places. There’s a 2% to 3% loss of mileage between pure gasoline and E10.

Not much of a difference in price anymore between E85 and gasoline in Minnesota. Typically 15-20 cents difference currently. The loss in mpg running E85 makes gas a better value.

The people that like using renewable fuel push E85. Problem is, it takes huge amounts of water to process the corn (or other sugar materials) to make ethanol. Huge amounts of water are also needed to do fracking - fracturing earth deep down to extract crude oil. Fresh water will be the next commodity and limited resource. RV campgrounds will eventually meter water like they do electricity at each campsite. You read it here first!

Truthfully, one shouldn't even use E10 in small engines. Unfortunately, real gasoline is getting hard to find.
Ethanol is the biggest fraud ever pulled on the taxpayer. Made a lot of people rich, though. Just not us.
