So i bought a used 2019 Yukon in February. Oil was changed by the dealer, DIC showed 97% oil life. Fast forward to December and the DIC is down to 18%, even though I have only put 1000 miles on the truck. Most trips have been 15-30 miles and there has been very little idling. My 2010 Tahoe would still have 85% oil life after 1000 miles of similar driving. The old system was not time sensitive though. Does the newer algorithm just deduct 10% or so a month to get to zero after a year of driving? Otherwise I have no idea how I would use 80% of oil life in 1000 miles.
