Lots of people love it. I am not one of them when I found out how inconstant the product is at the pump. If you can afford to run "Rocket Fuel" brand E85, I think it is a great upgrade, but with pump fuel, the quality is not always very good.

E85 wasn't created to make power, it was created to subsidize farmers.

Flex fuel completely takes away this concern. Sensor automatically adjust for an inconsistencies. Ethanol is amazing. Car runs smoother, cooler, and makes a ton more power safely.

I've never seen it vary more than 2-3% locally. Pump gas varies just as much from E7-E10. So all pump fuels are inconsistent by that logic.

I've been surprised how consistent it is here too so far.. basically E75 out of every pump I've used

93 showed anywhere from E5 to E13 for me

To answer OP's original question: higher octane, lower price per gallon, lower miles per gallon, make sure fuel system can handle it. Add flex fuel sensor if possible.

Overall I've been happy with it so far

Going to send injectors to ID over the winter to be checked out since they aren't the fancy new stainless ones

I recently converted the Shelby to E85, and I'm really enjoying it. Before then, a couple of local friends had been running 1100-1300rwhp in their Corvettes on pump E85.

Here's an article on why E85 makes more power: http://www.speedhunters.com/2015/04/...about-ethanol/

And here's one on why E85 can be dangerous: https://www.lmengines.com/e85-tech-information/

I bought my car new in 2006 and never knew that it was Flex Fuel.

Because... it isn't

Sensor is easy enough to add though

For the srock fuel system, yes -- and that's probably what I'll do on my C6 as well.

If you have a return style system, I guess you'd want to put it into the return line, and even then do it in parallel so as to not impede flow?

It flows too much to matter for 99% of setups out there, but yeah, most people with return style systems put them on the return line

DSX used to build plug and play setups and included a tube that went around the sensor too so flow wasn't impeded, but it was total overkill for most people so even they went to just running fuel straight through the sensor.

Pump gas isn't consistent. Anyone IMO should be adding a sensor. Even if it is just to run pump gas.

If you are converting to e85, spending the $100 on a sensor and making it flex fuel elminates the concern. That is probably the cheapest part of an e85 conversion.

Sensor can flow 1000rwhp. Very few people will hit that limit.

Cheers, guys. Thanks for the info! I'm over that with one car, and will be over with the other one as well. Neither can do flex, though, but both will run gauges just to monitor.

I'm not current, and haven't read the posted articles yet, but...

Hopefully e85 is mixed in a more accurate method than e10 (CARBOB or RBOB), which is mixed at the truck, and historically not always mixed perfectly (i.e., perfect at exactly 10% ethanol)...

Based on where you live, I think that there is a refinery just down the street.

Been filling up at Sheetz with E85 since September 2015. It's always been 80% ethanol at the dozen or so different stations I have used over the past 13 months.

I am planing on adding The DSX flex sensor to my 06 Z06.
What are the stock rails good up to in HP? If I change the fuel rails then I probably don't needed the dedicated sensor as I would have to change out the pluming anyway
What in the fuel system is not compatible with E85 that will need replaced or will die faster.

Id prefer to use the stock rails as long as I can.

I have a larger pump (Walbro) and larger injectors. But that's more for my power level than for E85 specifically, although E85 does require more flow as well so take that into account. I have not had to change anything specifically due to the higher ethanol content, just lack of fuel if that makes sense. Almost 20k miles on E85 right now and no issues. The Vette is right around 101k right now.

Flex fuel sensor is the way to go. I see 8-11% ethanol content from pump to pump.

8-11% is quite consistent IMO
