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.
