yea...and winter diesel this year SUCKS as opposed to any previous year. I am still getting 550km to 80L of fuel with my 33"s and my heavy @ss roof rack and a whole lot of donuts and bagging haha.

I wish I knew why your truck is getting such bad mileage, try switching conditioners...try the Redline stuff and see if that makes a difference. I know if I don't run any it makes a HUGE difference, my truck runs like a bag of $hit with nothing in the fuel
