My car hardly never gets to run as long as 20 minutes - I'm wondering if it will last the year out....
LOL...the first 20 minutes is something like the next full couple of hours...that's where they get the "70% (or 85%, or 90%) of wear occurs at startup" number that's used everywhere.
Doesn't mean that short trips will kill your engine this week.
The Colorado has GM's oil life monitor....15,000km, 9 mo nominal service
Follow it with the Holden Dealer's commute (local dealer, his "demo" family car, he lives in town), the OLM was 38% remaining at 4,400km...My commute took that out to 3% left at 10,480km, and 12 months
My commute on this oil change hit 50% at 8,100km...will probably hit the year at 16,000km.
