08 SD 6.4L Diesel
Well my mileage sucks and diesel is at 4.29 a gallon. I was thinking of trading my 08 6.4 for a 02 7.3. So I can run bio diesel and just get overall better mileage. My father has a 2000 7.3 with a mbrp turboback exhaust and a volant air intake and he is getting 20mpgs on the highway. So I think this is a good idea. can someone with an 02 7.3 tell me about there relaibilty, I heard they have head problems? but i really dont know. any help would be great. thanks
