I just bought a 2016 Colorado LT with 102,000 miles. I'm needing it for my sales job and figured if I was going to buy a high mileage truck diesel would be the way to go. Right now I'm having the full delete done except for the EGR it'll be turned off in the tune. The delete setup is coming from HD Diesel and should be here Friday. Any tips you could give me as far as longevity by using fuel additives, certain type of oil which with the delete opens more options I'd appreciate it. This thing will get much better fuel mileage than my 2012 Cadillac CTSV coupe for sure.

Welcome to the Forum! Not sure if you are aware or not, but the EPA is cracking down on the tuning and delete industry. Watch out!

Deleted, best bang for your buck Shell Rotella T-6 Shell Rotella® T6 Full Synthetic easy to acquire at wall mart.
Keep in mind a timing belt replacement is needed at 150K miles...
As far as additives go Power Service diesel clean, hot shot secret, Optilube. Any of the name brand ones that add lubricity are good for the high pressure fuel pump. GM is now recommending using an additive (of course they want you to buy it from them) but the reason is lack of lubricity in todays Ultra Low Sulfur Diesel Fuel (ULSD).
