Question:
Is it OK to use CF-4 Motor Oil in a Volkswagen TDI Engine?
I have a VW TDI 1.9 turbo diesel year 2003, 5000 mile oil changes. Currently using Mobil 1 5W-40 light truck diesel rated CI-4. Have used Mobil 1 15W-50 rated CF-4 in the summer, can I continue this practice or should I keep the 5W-40 year around and does it make a difference between the CF4 and the CI4 rating. I have used Mobil 1 0W-40 in winter which is also CF4 rated but VW 505 rated also, is this good practice, thanks BC

Answer:
We recommend you use Mobil 1 Turbo Diesel Truck 5W-40 all year as it is the best choice for this application.
