Chev 1.4 goes 6000, and has the gauge thing. So far it is only slightly darker at change, mostly town short trips. The advantage of synthetic was supposed to be longer life.
I did persuade them to change the first at 1000, even if they dont claim a need of break in any more
A shop wanted the sorento 3000 or 3 months--no way will i go back there that is not even factory severe requirement. The old f150 gets around 5000.
How much oil does it hold and how good is the filter?
