flex fuel question
 

Hi guys,I normally hang out on the 60-66 board but need some of your expertise today. I looked at a 2006 chevy 1500 to buy as a tow vehicle. It was very clean and low milage and had the 5.3L V8. So now I find out that this 5.3L engine is a flex fuel engine. I really am not interested in ever running E85 but was wondering what this board thought about the flex fuel engine that always will be run on 10% or less ethanol. Are there any disadvantages you guys know of with this engine. Thanks for your input and thoughts.

no prob running regular fuel.the pcm will test the fuel composition and adjust accordingly

No worries. I also have no intentions of running high ethanol blend fuel in mine. Most everything in the regular grade around here is up to 10% only. Some vehicles have a badge or decal on the rear showing it to be a flexfuel vehicle and some don't. I found out in the owners manual that one of mine is an ff vehicle.
But like I said, no worries.
