diesel maintenance questions

As an added option... if you are near a VW dealership, which is closer than your RAM dealership... VW dealerships won't carry your oil or fuel filters, but they do carry a C3 rated motor oil that works in your European Diesel motor, it is called Castrol Edge Professional LL03 5w-30. If it has the diesel 5w-30 VW 507.00 motor oil rating on the bottle, and they are European 1 liter bottles, check and see if it also has the ACEA C3 motor oil rating also. A VW 507.00 motor oil is almost always rated for a full 30000 km or 18,000 mile usage between oil changes. The LL03 spec is Long Life 30,0000kms or 18,000 miles. This is a good motor oil to use if you plan to do 50% of your mileage towing... and still go the full 10,000 miles between your oil changes. Just a FYI, the VW 507.00 spec in motor oil is a very high mark to have to achieve, mileage wise. It's the same spec used in the VW Touareg, Audi Q7 and Porsche Cayenne TDI diesel C30 spec motor oil.

The key to the proper oil for your motor is that almost always, it will come in a 1 liter motor oil or 5 liter motor oil bottle, not in the quart sized bottle.

Long time VW TDI and VW 3.0 liter TDI Touareg owner that tows with it.

Hope this helps.
