2008 Suburban Avg Economy
Hey guys,
recently purchased an 08 suburban and my avg economy always says 12.0, no matter how much the Inst economy fluctuates when I’m on mostly highway trips, etc. wondering if this is a common problem or have any idea why this would be happening. Thanks!

I assume the FF means Flex Fuel, which I have never owned. I have always heard that they get horrible gas mileage compared to a gasoline or diesel engine.
