Is it ok to run with E85 Gas for a SS T/C? Isn't the octane rating in E85 gas higher then primium gas. Wouldn't it make the car faster???

 

You need to be tuned for the extra fuel demand.

 

the LNF is not designed to run on E85 so no, however if you get a custom tune the engine can run on E85

 

word essssaaayyyy

 

The stock engine will run it fine... the computer will not... the new LHU in the Regal is an LNF with a different computer basically... and a few other little things.

 

I don't think we know what the longterm affects are to the fuel system that wasn't designed for E85. We're just kind of hoping that something doesn't eventually get eaten away.

 

Whether we like it or not, Ethanol is in fuel. Since the early 2000s (after the US Government dictated) Ethanol has been in commercially available fuel (this does not include farm use and 'off road' fuels). The problem lies in the degradation of the rubber hoses in older fuel systems. These days most, if not all, vehicles have metal fuel lines, either braided stainless steel or hard lines. These newer fuel systems aren't effected by the alcohol content of fuel. Ethanol will dissolve rust, plastic, rubber, and other stuff. Like when I used to run my diesel on 20%bio, I had to go through a fuel filter a week in the beginning, but the system was clean as a whistle after a few times. The Ethanol has a similar effect. Basically its like this... Ethanol is a solvent, weather it is concentrated at 10% or 50% or more, it has little difference. Over time it will have a similar effect.

 

Thank you for posting your inquiry. Could you provide additional information so I can look into this further? Send me a private message with the last 8 digits of your VIN and I will look into your vehicle specifically. I look forward to hearing from you.

^?

 

I know I had to get tuned and new injectors also, and I love it now cause its right down the road and only 2.95 a gallon

 

^ what you said!

 

All fuel system parts must be able to run on E for the last few years since they started using it in gas . Around 2000 I think

 

hey guys send her your credit card #! she said she is hooking me up with parts extra cheap!

 

trollin'

 

Trollin to get the peoples vins that are doing this and voiding warranties idk

 

Good to know. I just wasn't sure if the concentration of the E85 made a difference from the E20.

 

If you try to run e85 without tuning for it, the car is going to run VERY lean. It will run very poorly, knock alot, and cause problems if not tuned.

There is a major difference between the 10%ish concentration of ethanol in standard fuel vs running e85. While the fuel system may be able to handle the ethanol content, your tune is not set up for it.

 

Nonee26,

I apologize for my previous post. Upon further investigation, I have found that the Cobalt in general was not designed to be a Flexfuel vehicle. However, I can look into your model year in particular if you were to post that to see if there were any exceptions.

I should have been more thorough in my research for my first response, and again I apologize.

Thank you for your patience,
