Replying to: coontie57 (Sep 28, 2006 6:48 am) I must have had it FULL because it was slower coming up Saluda Mtn... just 56 mph today... and screaming.. Diesel in FL was $2.69+..... in Spartanburg $2.53 and in Fairview, NC $2.80... PHOOOEY I saw it on I 95 at $2.51 in SC.. |

| Bought my truck on friday, dealer filled it up, and i filled for the first time today. I logged 378 miles, put in 22.5 gallons for 16.8 mpg. This isnt too bad, but it was about 90% highway miles at 60-65 on flat iowa roads with little wind and no load in the box and nothing being towed. Hope this goes up when the engine gets broke in as my 2001 Dodge Cummins would regularly get 20-21 on tankfulls like that. | |
| Just picked up an '07 3500 4x4, turbo Duramax w/ Allison 6-spd, SRW. From Anchorage to Frb, 350 miles, rolling hills and some descent hills around Nenana, we got 20.5 mpg. Traveled mostly 60-65 mph. I was amazed that the rpm, 1600 at 65 mph, never changed on the uphills. My '93 F350 w/ a non-turbo 7.3 liter would have r'd way up and the after-burner kicked in many, many times. So far, so good. | |
| I am looking at new 4x4 3/4 ton pickups. I've always been a ford man, but the features and price on the new silverados are more appealing than the new fords. My big question is what kind of mileage to expect with the 6.0 in a 3/4 ton 4x4. I don't need a diesel (don't tow much, just need extra payload). Everyone I know have fords, so I need some input. | |

Replying to: rman6 (Apr 06, 2007 8:08 am) I am currently on the hunt for a 07 GMT-900 2500 x-cab to replace my 04 6.0 2500 x-cab, auto 4:10s. I can get 12-14 city......17 highway............. I note the new body style 2500s offer 3:73 rear gears so possibly can expect 1 or 2 mpgs more. Nice trucks but thirsty !!!! Since I need a 2500 for snowplowing and heavy towing I have no other choice. IMO a diesel for $7000 MORE and the possible few more mpgs is not worth it............

Replying to: rman6 (Apr 06, 2007 8:08 am) I understand that the 6L has gotten better.. hope so for your sake. On my Durmax diesel and Ford 7.3 diesel I get/got about 20 mpg with no load.

Replying to: geo9 (Apr 09, 2007 7:27 am) I am not sure a 6L gas engine would go that far without engine work.. The diesels will probably go another 100K or better.. The diesel is messy to fillup ,, it smells if you get it on your hands etc. Its just a personal decision.. the power and fuel efficiency is impressive with my new Chebby (as a friend calls it). |
