These mileages sound quite good. I guess I was expecting the worst after reading the DPF Delete posts. Yeah, I just wanted to keep it stock, keep the warrantee, save the hassle, and keep my lungs clean. Thanks, guys!
To and from work I fill up every 2 weeks and there are alot of lights and I may top out at 45 mph during the trip. I have been now averaging about 15 1/2 mpg. It's an 08 LMM that is now a year old with about 6,900 miles on it.
Overall miles..........113k.
City avg mpg's........15-17
