Well, it is $5000 problem. Maybe they make engine that doesn’t need such oil? MB, BMW etc. are running low-SAPS oils since 2009 in Europe in gas and Diesel engines. I don’t see taxis disintegrating at 100k or numerous BMW police vehicles.As I said in another post, Chrysler may be more worried about the engine than the DPF with all the trouble they've had. MB and BMW seem more worried about the DPFs.
