Are 2012 6.0 Gas Engines Flex Fuel?

[pm26]

I read somewhere that all 6.0 gas engines will be flex fuel type for 2012. Is this true?

Not sure where you read this but I don't think this is true - from what I understand no performance changes will be made from the current 2011....here is a link to what I have read and seen elsewhere as to the changes for 2012:

I heard that rumor too about a year ago that it was upcoming.

I believe the 6.0 in HD's is flex fuel for 2012.

Thanks, yes it has the FLEX FUEL badge. Nice truck, BTW. I would trade mine for it, but I cringe when I think about the difference I would have to pay($ 23k?). Man, those prices are going up. Just four years ago, the same equipment truck with Duramax in it cost this much.

Last I checked flex fuel really wasn't worth any savings benefit. Has that changed?

The reason why I like flex fuel engine is not because I want to use E85. E85 is not even available in my area. But with 10% ethanol being added to gas and EPA pushing for 15% now, it is always good to get an engine with stainless fuel lines and other protection for corrosive ethanol fuel. This way even when gas stations illegally dump more than 10% ethanol in the fuel, you are protected.

I have run E85 about 85% of the time so far in my 2010 (Nov will be 2 yrs).

Yes they are.

You can now go onto GMC's website and build a 2012 & yes it states under the specs for engines that the 6.0L is now flex fuel capable. Awesome!

One step closer to getting that 2500HD...

The other good thing about getting a flex fuel engine is that the injectors are "bigger" so if you want to get a blower later the fuel system is setup better for it, as the regular 6.0L non-flex fuel injectors are pretty maxxed out from the get go. That is why you see guys getting the old big block injectors when things get serious on a 6.0L setup.
