Default e85

What will it take to get my L27 to run it. This stuff goes for $2.30 a gallon around here. I'd seriously love to know if I can run it, and if not, what it would take to run it. I've heard you can modify an L36 or an S2 L67 to get it to run E85, so what would it take to make the L27 run it?

Not sure what it would take on an L27, however if you search E85...there have been a couple of threads that may shed some light in your quest.

Keep in mind your A:F will need to richen up to ~11:1. Your mpg will be lower so, it may be a wash on cost/mile.

Yea, you will lose mpg. Our '02 Tahoe is flex fuel but we never run it 'cause its not cheap enough for the mpg loss around here. IMO flex fuel is not the answer to this country'* problems but that is not on topic for this thread.

My brother has a flex Tahoe, also. He says the E85 saves him money, even after the MPG loss, so he fills up on it whenever he can.

Will it work out with a retrofit kit? I don't know.

I'm kind of bound on what I can actually talk about, but I've spent the last 2-2.5 years at GM working directly with E85 and engines. Can't get too specific, but I'm going to make somewhat of a blanket statement -

Because of the current state of E85, I would not recommend retrofitting an engine to run it. There can be significant issues in other areas of the engine and fueling system that people don't know to look for yet. Hold off on using it until you have a car that'* designed as a flex fuel vehicle from the factory.

Also, with the variation that exists in the actual product, if you choose to run E85, I would occasionally run a tank of gasoline. In our tests (random samples of E85 stations in Michigan), the product ranged all the way from about an E60 to an E92 depending on where you were and what time of the month you visited.

We're used to gasoline, which has been refined over the course of the last 100 years - there'* not a whole lot of variation in those products. E85 isn't quite there yet, and I wouldn't risk an engine too it that wasn't originally designed (as a system) to run E85.

It depends on where you are located. When we travel we can find some good deals but in our area(St. Louis area) it is not justifiable.
