5,000-7,500 without used oil analysis on mobil 1 or pp in both cars and the truck. although im considering switching over to mobil clean 5,000 in the cars that i like to change twice a year.
used oil analysis are greatly over-valued here. You only need two or three and then you know too much already!
Seriously, once you get the trending it is easy to figure out.
We have killed dozens of GM vehicles since the OLM was introduced. One recently sold had half a million miles on it and was quiet as a mouse, no oil usage at all. ALWAYS serviced via OLM since brand new.

Speaks volume.
What oil/filters were you running?
Although not entirely necessary, I use a synthetic oil filter (WIX XP) for that extra peace of mind. I wouldn't mind running a PF61 if it were available, but I'm just not too big on the PF61E, which is all I can get locally. If I am buying the filters from the States, might as well get something worthwhile.

Obviously the OLM would tell you the oil is ready to be changed before it actually needed to be. Is there some sort of math people use to decide when to change the oil. Let's say for instance whatever miles the OLM says to change the oil add 50% more miles to the total. Was just curious.
61bsoft,
I trust and use my OLM all the time! When it's time it also serves me to have my in addition services done at the same time.
If it designed for dino then I'll use a synthetic (Mobil 1) as a cushion just in case to keep the motor in it's most possible peak. So far my OLM tells me to change every 6K.

We run whatever synthetic is on sale with a name brand filter. Probably the first 100k miles was all amsoil as we used to use it exclusively.
When it was sold I started it dead cold and then showed the man my brand new 2013 van that is noisier!
