Hello,

My 2007 Commander Limited is equipped with the Flex-Fuel V8.
My question is is it ok to continually use the E85? It is a lot cheaper obviously and I know you get less fuel mileage because it doesn't burn as good as unleaded gas.
I am in the process of gathering information to determine which is the better value. Cost vs millage.
I know you shouldn't mix the two and you should have a 1/4 of a tank in before filling back up with the opposite type.
And your oil should be changed more frequently.
But my main concern is, is it harmful to your engine. Does it cause more carbon build up or anything?

No, it won't cause any adverse problems. E85 is actually a much better fuel to run, and isn't far from race fuel formulas. It'll also actually help your engine run cooler and produce more power.

E85 is completely safe;

I have the 2008 4.7L Flex Fuel V-8 and I have run it before - it's actually quite a bit cheaper than regular gas and burns cleaner.

The problem is, there aren't too many gas stations that sell it - at least not in my neck of the woods.

Thx guys. I must be lucky then. I have 3 stations that sell it within a mile or two from my house.
I guess I was listening to to many wanna be mechanics.

Yea, you are lucky;

There is only 1 station in my area that I know of that sells it.

You will notice an increase in acceleration as well as around 15% less mileage based on my previous experience. Have to do the math $$$ on the trade-offs. I was commuting some distance before and the trade off to stop for gas more often did not work for me.
