my mom and step dad run E85 in their vans all the time. just do the conversion and your all good. both vans are chrysler town and country, and his van is a dodge caravan 4 cylender. so if a 4 and 6 cylender non turbo can you can to. i cant remember where to buy the stuff for the conversion but i know its good and it works very well.

Nope, no shame in asking. Just that the system will adjust and remap the A/F for the different fuel.

But, the main drawback with E85 is that the high alcohol content could destroy rubber seals in the fuel pump, plus anywhere else where rubber and fuel come together and bring up any content that the alcohol will break loose (since alcohol is a very corrosive fluid by itself) up to the fuel filter and clog system real good.

Why you see a lot of turbo owners use E85 is that the octane rating is over 10 points higher than the highest octane of premium fuel. Thus, they can really shoot the compression ratios a lot higher, but the big drawback with E85 is the BTU output is lower than regular fuel. Thus, it takes more E85 to produce the same BTU (power) putput if they just stayed with RON 93 premium fuels. E85 really was contreived as a economical ploy - cheaper priced gas, but doesn't have the punch as regular fuels ... and your mileage suffers also ...

The new vehicles that are E85 certified have made the proper adjustments to protect against the corrosive nature of alcohol in the fuel and injection system.

Best stay with standard RON 85/87 regular fuels since you're a N/T.

Good luck - DSM

Best advice/explanation I have seen in a long time.

so if i was running preimun fuel in it would be better then e85 then.rite or should i stick with super unleaded thanks agian guys.

Why are you fussing with Premimum if you're an N/T that doesn't need it (unless you're just asking a simple question, or have modded that N/T to a turbo)?

Stick with 91/93 RON. Let the new cars handle the E85 stuff.

I tried a couple of gallons of E85 in my turbo and wish I didn't. Lost performance, mileage, it idled horribly... I ran the tank out and went back to the conventional stuff and I got the car back to normal.

good luck -DSM

Just about everything said about E85 is true EXCEPT that all cars mfg since the early 80's were mandated to be alch proof due to the blending of ethanol into every grade of unleaded fuel. The problems people see switching to E85 are very similar to problems seen with switching to synthetic oil. Any weakness in the system WILL show up. I personally had to replace the 20 year old fuel fill elbow on my tank due to the e85 accelerating it's slow death. All in all E85 is easier on your overall system than say leaded race gas (O2 sensors, valve deposits, etc.). Pretty much anything you do to increase performance is going to shorten the life span of some component, it's part of the price you pay to play.

All in all there is no solid reason to run E85 on a stock N/A 4 cylinder, it's cheaper than race gas but not cheaper than regular gas considering the extra fuel (not to mention injectors and fuel management of some kind) needed. I think Darkstar has enough on his plate getting his car running first before considering a swap to E85...

BTW, you can run regular (87 octane) fuel in your N/A, why pop for 91-93 unless you plan on storing it over the winter?
