The so call " New Technology " became so confusing. And instead of making engines that last longer, it's the opposite. Even diesel motors, does not last as the ones built prior to the year 2000. I'm wrong? The up keep is so expensive. All this electronic shit, now comes the kill switch. I remember have to drive carefully, other wise my father would activated the kill switch, taking my keys way. Now? The big papa goverment , will do it without taking the keys way! But it's all for our safety, nothing to see here.
Not so sure about the lasting longer prior to 2000. I just traded my 06 Silverado with a 5.3 that had 267,000 miles and still going strong. Mobil 1 was the only oil ever used since new.
