Parked and Idling. Bad Idea?
2014 F150 XLT 3.7 Flex running on E85.

Another thread here got me thinking about this. Sometimes if I'm waiting in my truck, I let it idle with either A/C or heat on. Usually no more than a half hour. Or as the other post, maybe I might need to idle for an hour or more. I have not done it that long, but if I had to.

Is it a bad idea to do this?

Thank you!
Tom

You can certainly build up carbon in the cylinders, spark plugs, etc. and "excessive idling" does require increased oil change frequencies

not to mention that "idling" is bad for the environment...

I know they are labeled as Flex Fuel vehicles but I cringe at the thought at putting E85 in any of my vehicles

Seems to run a bit better on it. Also, I started using it when regular grade gas was almost $6 a gallon and E85 was about $3.

You get a custom tune on that 5.0 like I have on mine and fill up with E 85 and hold on. The increase in power and torque with just doing those two things will blow your mind.
