Default 6.6 duramax vs 6.0 gasser

I am looking at getting a truck... I am considering a duramax 2001-2004 model year or a 6.0 chevy same years what are your opinions on those trucks I don't need a diesel but I would like one but most people I talk to say don't buy a diesel. The gasser is going to be about $3000 cheaper than the diesel where I live but I wouldn't mind paying more to get a diesel. Just wondering the pros and cons of both. Thanks in advance

If you dont need it, dont buy it. Make a list of pros and cons. Diesels can be more expensive to maintain and operate.

01-04 Duramax is harder to change injectors on, I’d find an 05’-06’. I liked my 6.0 once it was tuned and about 3 grand under the hood, but I didn’t tow and it only got 10-12 mpg.

If you can write everything that you do to it off as a business expense like many of us , then it can be fun but if you can not , then it may not be so much fun ! Or if $ is no object then go for it , but since you were weighing out your financial options , I would follow Toms advice . Good luck on your decision !

Yep. 04.5 or up. Lb7 injectors suck...

Thanks for all the input I guess I will have to wait and see what comes up in my area... right now I have a 86 f150 that I just rebuilt the engine on but I only get like 5mpg so I want something with a little better fuel mileage.

The 6.0s get poor fuel mileage , as previously stated , 5.3s get good mileage , if you do tow in hilly areas and need more torque do not rule out finding a low mile 5.7 350ci that an old man bought new and his wilf is selling it at a good price because the 1998s are a great truck , I still have mine I bought new, lots of torque and good fuel mileage ! Good luck !

6.0 are reliable engines and tow pretty decent but mileage is crap. Itís goung to be 12 or less regardless of how easy or hard you are on it. Duramax get good mileage and tow great but like has been said, when, not if, something goes wrong. Itís Expensive. Iím gonna go out on an unfavorable limb here and say if youíre wanting something that cheap ish to maintain yet tows good with good mpg, 12 valve Cummins with a 5 speed. Yes itís going to be more expensive to fix and maintain than a gasser, but not as difficult or expensive as a duramax can be. Just my .02.

For what you’re wanting to do I’d get the 6.0. Unless you’re just a gear head and want a diesel just to have one. Yeah the mileage sucks but in my area gas is about 60 cents cheaper a gallon. It will take a lot of fuel to pay for the set of LB7 injectors that you’ll eventually have to buy.

Again if your a gear head and want one it’s hard to beat the sound of cracking one off first thing in the morning. Unless you can do the up keep and repairs yourself they have the potential to eat a hole in your wallet.

As all others have stated. I've owned both. The 6.0 gets 12 running around or highway. The diesel gets 15 running around or 18 highway. But maintance is expensive. The 6.0 is easy to work on and a great motor. Don't buy an lb7 if you don't turn wrenches. Fuel is cheap compared to maintenance
