The Jeep & the Caliber get 5w20 Castrol Edge High Mileage. Wix XP filters except for the Porsche.
Thx for the replies.
With that kind of diligence, there won't be a problem. The ecotec's that nearly universally experienced balancer chain failures were going over 8000 miles between changes on cheap oil due to dealer service and poor OLM settings. But it's good to note that the failures did occur WELL before the warranty was up. So, the wear rate was very high.
Also, the few UOA's I've seen from these engines never indicated a serious problem.
