I’ve just completed an 8,200+ mile, two month trip and found some great news on the first half of my trip in which I had NO toad. East of Arizona, the highways are nice and flat. BUT THE BIG DIFFERENCE WAS I NEVER WENT OVER 65 MPH!
I normally use PS DIESEL KLEEN as well.
In our 2015 Newell with the ISX, I maintained over 8 MPG, and even went as high as 8.8 on the last leg to Oklahoma. It blew me away, so I started to back up the computer with old school fill-up gallons, divided by miles and it was darned close!
The life average on our coach was 5.7 until this last trip. My average calc over this entire trip was well above a 25% increase! Yahoo
The key take-away for me and others I’ve shared this with is to drive slower; 65 and under. It’s less stressful and even with a LONG drive day of 10 hours, you’d only lose 55 minutes. It’s worth it!
