I just came back from Newfoundland Canada after staying a week and putting 2200 miles on the truck. I had no problems except trying to avoid paying for diesel on the island which is $1.07 per liter :eek: . The truck ran flawlessly except for a shake in the front which I hope to correct with new michelins tonight. I got about 19 mpg (would have been better if I could have gone faster down the big hills to help climb the other side without downshifting but I had the shaking problem) and used 12 gallons of WVO. This was only a 10% blend not 25% per my signature but that was all the room we had for oil. Speaking of hills, 10 % grades, are you kidding me? I had forgotten how hilly the island and Northern Maine could be! Just one more "love my 6.5l" story.

19MPG is excellent for a big suburban. One of the excellent virtues of diesel :) I'm stuck with 17MPG on the highway with mine because of the 4.10 gears, but I'm still pleased with the mileage. A gasser would be lucky to get 12 to 15 on the highway with this truck.
