Ok.. the wife purchased the car brand new in 2015, because I wanted her to have a diesel SUV that was AWD and because Mercedes was giving them away for $10-$12k off of MSRP on the heels of the EPA lawsuits. They have the European Sprinter 2.1L, twin turbo, 4 cylinder diesel that is supposed to be rock solid.
Well, at 128k we smoked both turbos and the car just came out of the shop with an $8k bill from an independent shop that has a phenomenal reputation. The car has been paid off for 4 years and it is in super, great shape, so we figured we would roll the dice and see if we can get another 100k out of it for $8k.
Anyway.... the shop wrench told me in passing... you have to quit using that crappy 5w30. The only thing we put in all the Sprinters that we work on and service is 15w40. He said, your turbos probably failed because you made two bad decisions... 1. 5w30 and 2. 10,000 mile oil change intervals.
He wants me using 15w40 going forward and doing 7,500 mile OCI's.
He said if the sump was 12 quarts, he would be 'good' with 10k OCI's, but it is only 7 quarts.
I guess my Benz is going to get a regular diet of Rotella T6, 15w40 going forward.
By the way, the European spec for this same engine in Germany is 15w40. UGH....
