Farmboytoy

1969 Blazer with BBChevy
I got 17 mpg highway hand calculated on a trip from Idaho to South Dakota in my wife's 6.2L awd yukon xl. Its at least a 5,500 lb pig. I don't even bother to calculate around town mileage. It takes premium too!
 
16 mpg out of 6.0? You got proof of that?
I can show you proof of 15mpg out of my 93 454.....
Yep. 16 around town 19-20 with cruise on the commute @ 75MPH. Closer to 21 if I set it at 65
I’m not arguing, I love my big block too. My Chevelle did mid tens when I was running it @ the track but 10 MPG in my experience is more like a good average for a normally driven big block Especially if there are performance added & a slight heavy foot. My last 6.0 got 385k miles without a tear down & I see the guy I sold it to is driving it every day. You are right about choosing what you want to do with your engine & making the right choice. I don’t need all that torque for my purposes.

I tend to drive with a heavy foot. I bet my wife has a much better average...I don’t swear by that little 6.0L but my experience has always been more abuse higher mileage & less issues but I’m not in need of 500lbs of torque anymore
