Yes, either reset it or just clear the message upon start up and reset when you actually change it. If you have an active OnStar account a red X is marked on the miles whenever you reset it. It's apart of the online stats not shown in the mobile app.
Interesting. When I got my oil tested, the tests showed some abrasion after about 18K miles, that was why I backed down to 15K.
Bear in mind we have people going MUCH longer on diesel oils in other diesel engines than even 18k. I wonder if that analysis report was an outlier. Just saying; if the filtration is up to par, and the oil didn't oxidize, you should be good to go.
We see very high levels of fuel dilution in big rigs and other light diesel trucks. It never really leaves any cause for concern unless it gets above around 5%. As long as the wear metals are low, you won't have a problem. Your fuel dilution is likely setting in very early; I'll bet you'd see significant fuel dilution even at half that interval.
Brad has his EGR blocked off if I remember correctly. His oil should last twice as long as those running EGR's.
Not to mention that even their rated intervals are for 15K or ONE YEAR, whichever comes first.
Why? Oil changes are cheap! About as cheap as taking a sample and sending it off. Good insurance in IMO and you dont have to argue with GM about a 30k OCI if something goes wrong....
There is no real advantage to what I am doing. I still go to the dealer every 3 months for filter changes, oil sample and tire rotations that are about the same price if I had the oil changed. I also have to pay to send the sample in. There is no cost or time savings in my technique. I just enjoy doing it this way.
They are not that cheap in the diesel.
To do it yourself is appx $50-60, at my Chevy dealer $75-90, I will probably just do my own.
bingo!!! exactly........oil change is cheap maintenance.
Our dealer does CTD oil changes for $40, which is what has made it hard for me to pick out a synthetic to do myself - too **** convenient and cheap (and I already have three other cars I do the oil changes on myself).
