I bought a 2005 2500HD, Diesel, 4X4 crew cab short bed with the Allison
automatic about 2 months ago. Replaced a Dodge 5.9L, 1/2 ton auto...
We put 500 miles on it then hooked up the small 5th wheel and made a couple
weekend trips locally.
Then at the end of September headed out and went 5950 miles in 5 weeks, just
I did an initial oil change at 1600 miles and I"ll be doing one tomorrow at
I"m also going to get the tires rotated. Gave it a thorough bath today to get
Montana, Utah, Wyoming, and Colorado off...
I've looked at the maintenance schedules and I'm wondering how optimistic they
are? It LOOKS like I'd be doing an oil change about every 10K if I followed the
oil life indicator - which in a gas engine would be a major no-no... What about
the diesel? Do I treat like I've always treated other machines and change the
oil at about half the recommended intervals? I'm already figuring on having to
use the severe duty maintenance intervals so it'll get a transmission server
every 25K instead of 50K. And a fuel filter every 10K? What other maintenance
actions should I add?
What about additives? I talked to a diesel guy at the local Chevy dealer and he
recommended dumping their additive into the fuel tank with every oil change...
Good, bad, indifferent?
Differentials... Do I need to change the fluid there now? Soon? Never? On
the Dodge I changed the diff fluid every 12K, which was the severe dute
schedule. What about the Chevy? Apparently the rear uses synthetic.
Should/can I put synthetic in both front and rear? Any benefit to this?
How about engine oil? I ran the Dodge on Mobil 1. Didn't seem to do any good
as far as longevity OR mileage... What about the Chevy diesel? Any point in
synthetic engine oil?
Since we tow I've been thinking I might want to add the exhaust gas temperature
and boost gauges. Good idea? Waste?
And the last one I can think of right now - shutdown... Do I need to do
anything different when shutting this thing down because of the turbo? Let it
idle for a while? Do I need the boost gauge to give me meaningful info?
After 7500 miles, and about 5500 towing, my wife is in love with this thing...
She may NEVER go back to a gas truck! We DO have one complaint... The cup
holders in the middle of the bench seat could be more convenient! They're a
