ExxonMobil engineered Mobil 1 Turbo Diesel Truck 5W-40 to help extend engine life in modern turbo-charged diesel engines, even those operating in severe conditions such as towing and hauling. This formula meets the latest industry standards, including CI-4 Plus
Not really - the CI-4+ oils are required for EGR engines, which doesn't include the Cummins (yet). Looks to me like they're getting ready for the Tier III engines (1/1/07 emissions regulations).Turbo Thom said:So what that tells me is they didn't have a compatable oil till now. Some company's are so slow. And some folks are so stubborn about trying something else.
Mobil I Truck & SUV carried an API CI-4 rating (Delvac I was already CI-4+). The new Turbo Diesel Truck oil is CI-4+. I haven't seen the spec sheet, but it's probably very close to Delvac I, if it isn't Delvac I repackaged for the consumer market.barbwire said:I have been useing Mobil 1 Truck & Suv 5w40 for at least a year now. although it was hard to find after Katrina. So what is different about it now?![]()

Cooker said:My guess is they are repackaging the same oil again. IMHO it (Truck & SUV 5w40 and M1 Turbo Diesel 5w40) is all Delvac 1. The way it is marketed is the only difference.
