I have a 2004 3/4 ton Silverado 6.0 that I bought new. It has been a great truck and really no expense other that oil changes and gas. I recently got rear ended and messed my truck up pretty bad and am going to trade it in. I am having mixed feelings about what to get (Diesel or Gas) This truck got around 12 in town and as much as 15 on the highway (I live in the mountains) I have been wanting a diesel for some time but I have been reading a lot about maintenance, oil changes, diesel fuel additives (As it does snow alot up here..darn global warming), and crappy gas mileage. I have been considering buying the new GM 6.6 LMM. Do you thinkk buying one of these would be a risk or should I just stick with a gas. I also do pull a race trailer (24ft). Thank you for your time and input, I really do appreciate any knowledge you have to offer. (Oh and is 10 mpg increase in fuel mileage really that plausible?)

If you like the gas engine, I would stay with the gas. Diesel prices at the pump are a little scary right now. Not to mention that the price of the Diesel motor is about $7K more and the annual servicing cost are more also. You will never earn your money back on the cost difference. Now if your looking for power then the Diesel is the way to go as long money is not a considerations.

Thanks for the input. I just wish that fuel and oil prices weren't so high and it wouldn't even be a question?

Hi, I have a 1995 F350 dually with the 7.3l diesel motor. It is stock and I am getting around 14 around town and 17 highway with no load. What would be the best bang for the buck I could use to increase my fuel economy? I don't really need more power and am only interested in using less gas per mile.
Your mpg is very impressive!

It is quite possible that all reported efficiency gains with aftermarket mods is due to the placibo effect.
So the best bang for the buck would be for you to drive your stock F350 as if you had just spent $1k to . . . ($4k?) on aftermarket mods and you are implementing the driving practices recommended by the producers of this gear. Don't they claim something like "their mods maximize the fuel economy gains of careful driving"?

What is the max towing of my '07 F-250 CrewCab 6.0 Diesel, Automatic. It is completely stock from factory, I am thinking of buying a travel trailer, possibilly 35 footer. I see the trailers weigh between 7,000 and 9,000 lbs, these are towable and not 5th wheel.
Thanks

i've seen tuning chips ranging from $50 on Ebay to $500 elsewhere. is there a difference? does the chip significantly improve the fuel economy? does anyone have a link to any independent testing done on them? also, what about other options like cold air intakes and direct flow exhaust systems? are these things going to considerably improve my mileage as diesel soars? right now i dive my 02 tdi easy and get about 46 mpg on the average. thanks for your help and input!!!

No tuning chip or reflash of an ECU will improve mpg without risking engine damage. Just continue to drive carefully and do all maintenance on schedule.
Everyone wants a VW diesel right now; you are lucky to have one. Don't ruin the vehicle by messing with the engine controls.
A chip can improve torque and power by over-riding the mfgr's turbo boost limits and fuel program, but this will come at the expense of greater fuel consumption, not less, and risks engine damage and provides a basis for denial of warranty if you do have problems.
Be happy with your 46 mpg. Don't be greedy!

PS Cold air intakes have no proven benefit. "Direct flow" exhaust systems change the back pressure that the engine designers have selected, and could be at variance with state and federal environmental laws and regulations.

I guess VW diesel are deferent than every other diesel out there because everything your saying is not true of a diesel truck. I have a cummins and it is proven that all of these things will give you benefits/gains. And as long as you monitor all your important readings, EGT, Boost etc...you shouldn't have any problems. But I guess all of this could be deferent do to the nature of the vehicle. But still a diesel is a diesel. All of the factory settings are de-tuning your motor and holding it back. Because of emissions regulations and trying to be friendly to the environment. Every diesel motor made today for street use has the potential to make more power and be more efficient, but with the fuel these days and emissions they are held back. But yes if you abuse the extra power you can create there is always the possibility that you could have other components that might not be able to take it. Which is where the VW could be deferent. But every diesel truck can handle the slight gains in power if you are just looking for MPG increase and not trying to make a drag truck.
