ZZ4 MPG Challenge II report - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I finally went through my final full tank from vacation. I filled up the last tank fully used on my trip. I was surprised at the milage. I drove a little over 2 hours at 65. Only because it was night. As soon as daylight came up, I speed up to 70 MPH. I think the ZZ4 could average 22 if I kept it under 65 MPH. I was short 63 miles to reach my house from Lubbock TX. Drive was almost 4.5 hours.

Odometer Miles Fuel MPG
76131 Starting point
76430 299 15.674 19.08 one full tank at 70 MPH
76686 256 14.962 17.11 showing off

76865 179 15.561 11.50 really showing off

77197 332 15.193 21.85 65/70 MPH mix
Total miles = 1066

I'll need new rear tires by the end of summer for showing off. :biggrin:
