| I have a diesel now and am considering going with a Chevy or GMC 6.0 liter gas engine. My boat motor and trailer is about 4,500lbs. Anybody out there with a 6.0 liter Chevy/GMC, have you noticed a huge drop in gas mileage pulling comparable weight? If so how much? Any transmission problems? |

Location: Eagle River, WI | There's no way you could ever get me to trade my diesel for any gas engine. You'll be lucky to pull 10 mpg with that 6.0, and that's assuming your running the standard 4.10:1 gear ratio. If you are running the 3.73:1 you'll probably be even worse.
If you need to up your fuel mileage on your deisel there are a bunch of different things that you can do. I have a 2007 dodge ram 2500 with the 5.9 cummins common rail in it and I'm getting 22-24 hwy on the trip computer. Now pulling my 1850 crestliner I'm getting like 15-19 depending how hard I'm pushin' it.
I'm running the standard exhaust but I put in a Edge programmable controller that I have set at 75 more HP, and I am also running a K&N cold charger kit. I'm also rolling around on 35-12.50 coopers.
Just my opinion but I would never trade in a diesel for a gas any day. |

| not true with the 8.1 I got rid of my 2005 power stroke that got about 12.5 mpg pulling a185 tourney pro running 75to80mph on interstate and now am pulling with a 2001 sub with the 8.1 gas and get 11 mpg the plus is gas is .85to 1.15 $ cheeper. ps I think you will be disapointed with the 6.0 comming from a rattler it will do the job but very under powered compaired to the the diesel or 8.1

Location: Grand Rapids, MI | I drive a 2008 powerstroke with the 6.4 diesel, and a Hummer H2 with the 6.0 gas. The diesel has tons more power both off the start, and going up hills with my 3500lb boat. But it only gets 9mpg. The H2 tends to downshift more often, but I'm getting 11mph with that. Plus, gas is .25 cents cheaper. |

| ^this is why you should avoid like the plauge the 6.4 Ford or the 6.7 Dodge or 2007 or newer Chevy/GMC diesels. DPF technology is not fully worked out, and at this point in time it kills the mileage. basically, diesels aren't worth it unless you actually have to pull over 10000 lbs. they may even be better by the 09 models, but i haven't checked yet.
i'd have to check, but i think 3.73 is the tallest gear ratio you can get with the 6.0. smaller #s = better mpg. with a 4.10 you'd be turning higher RPMs on the highway, which means you're burning more fuel. i also have the 5.9 Cummins, and the worst i've ever gotten under any condition is 14. welldriller...check your mileage by hand...my last tank the computer showed 25mpg and it was actually 19.5. maybe they have better software in an 07 vs. 03, but in my overall experience the trip computer is completely worthless for those numbers.
back on subject, the 6.0 will have plenty of power to tow your boat. the transmission will hold up just fine. any half ton these days will do the job. what you need to sit down and ask yourself is 'what will i be doing the majority of the time with this truck?' you'll see a much bigger difference in mpg towing/not with a gas engine than a diesel. gas is cheaper, and if you don't have another car, the gasser wouldn't be a bad choice. if it only serves as a tow vehicle, then just stick with another diesel, since you're used to it already. |

WOW that is about the worst milage I heard anyone get with the 6.4L Powerstroke.
I have a bunch of friends with the 08' 6.4L and they are doing much better than that. Is your truck a dually with the 4.10 gears or are you a single rear running 3.73's
I have an 06' F250 with the 6.0L 3.73's I have a 4" turbo back exhaust with muffler delete and I'm running the SCT X3 tuner with 150hp gain and right now on winter blend (kerosene/diesel mix) I'm getting 21.5 mpg highway hand calculated. Once we get off the winter blend I should be getting around 23 mpg |

| I've been out of the "car" business for 3 years now. But I'll tell you that the late model diesels (2004+) are impressive, power and mileage. Are they worth the extra cost? you decide. 4500# towing is well within the towing capacity of a gasser, at lower fuel prices (remember the fuel prices last summer). Before my personally selected demise (couldn't make a decent living) at Ford I seen the technology in both gas and diesel pickups get much better, I'm sure the other manufacturers were very similar in results. I have driven and worked on all of them, and they are not that different (manufacturers), so picking just one" brand" is more a matter of personal preferance. For me at least I picked a gasser because of lack of easy availability of diesel fuel where I fish in Canada, also for my local endevors the gasser does fine. Bottom line, either will fit the bill, while you think of your boat as heavy... it's not.. it doesn't get really interesting till your towing 7000+. |

Location: Lower Manitou Lake, Ont. | I have a 2001 chevy crew cab long box 6.0 gas and get around 13.5 on the hwy and 10 in town. I also have 2005 chevy crew cab long Duramax and get approx 20 on the hwy and 15 in town. Both the exact same truck and I drive them both. I am thinking with the stories I here about the new duramaxes, that my next truck will be back to Gas. |

| I have a 2003 GMC 2500HD 4x4, 6.0L, 4:10 gears, 285 75 R16 tire. I pull a 18ft Tuffy Rampage and I see about 11-12mpg (70-75mph). As much as I would like to have the extra power of a diesel, the cost of ownership isn't worth it to me. As mentioned in an earlier post, coming from a diesel you will probably be disapointed with the 6.0L, but it does a fantastic job pulling my rig. I am going back down to 265 75 R16 tires to improve handleing and performance. Good luck |

Location: Twin Cities | I've done a trip to KY from MN with a 7.3 powerstroke and my 5.3 gasser and I know someone who followed with a cummins. The powerstroke got 13.7mpg and the 5.3 got 17'ish. This was when diesel was $4.25, ugh bad idea! The cummins was pulling down 19-20mpg. The boats are all fairly small, 16 foot aluminums.
I'd get a diesel in a heartbeat, just not a powerstroke. The ford trucks are so much bigger/heavier, they have a lot more weight to push around...I have another friend with a duramax, driving at 65mph empty he can pull down 22-23mpg. |
