Ugrade to Diesel? Possibly?
So I'll lay the fact pattern for everyone:
Currently I drive an 04 Silverado 5.3 V8 4x4, love the truck. Bought it from my dad to start a small odd-job business, plow, mow lawns, dump runs, the whole bit. Made some decent cash so far. After owning for 2years now, my avg MPG is 15.1 after numerous upgrades/improvements. I'm going to be commuting to a new college in the spring, and it'll be a 65 mile round trip day, 50/50 back roads and highways. So I figure my options are to a) get a small commuter car to go to school with and keep my truck for work, or get a truck with that will give me better MPG. I've scoured the forums here, and from my own friends with diesels, see that you can get anywhere between 15-22ish mpg, which would be awesome. I'd also like to upgrade the lawn care with something like a kubota or whatnot. So basically, I'd like to upgrade to a duramax, but just wondering what others with experience can tell me. Thanks everyone.
p.s.- i also put this thread in the "Diesel Tech" forum as well.

If your current truck does what you need it to do-plow odd jobs- I would steer clear of the diesels.
Diesels are great for heavy work-towing- but you are pleased with what your truck does now(except for the MPG), so you don't need the Duramax.
The downside to the diesels is
1)You have to pay for a new, or new used, truck.Your current truck is almost paid for, right?
2)Diesels fuel costs 10% more than gasoline, so any potential mpg improvement is lost to the extra fuel cost.
3)Diesels are EXPENSIVE to repair-the fuel injectors, pumps everything cost big $$- much more than typical SBC stuff. The diesel motors usually don't break, but the injection stuff does. Besides, how often to gasoline 5.3 and 5.7 actually break-rarely?
4)Diesels are more expensive to maintain-14 qts of oil etc-and they are really sensitive to "dirty oil" and to a bit of water in the fuel.
I would stick with what you have-
I do know how much fun it is to get a different truck/car-the fun aspect is worth something!
PS- Yes a 375 hp 700 lb ft diesel would be fun!

Yeah!! What Charlie said... Right down the line, point for point, those are the reasons for not getting a diesel, unless you have a lot of extra money to spend. If you don't like the mileage your trucks getting, then opting for the small economy driver for your 65 mile commute sounds good.1988 Chevy C-3500 2wd (no pic)
