Need to Switch a Volkswagen Jetta TDI Off Mobil 1 0W-30?
Hello, VW Jetta TDI. I think I put the wrong synthetic in. I used the Mobil 1 0W-30. I thought it had a CD rating. Your web site recommends Mobil 1 Turbo Diesel Truck 5W-40. Should I change it? or will it be ok until the next oil change?
-- Tom Jeleniewski, Templeton, MA
Mobil 1 0W-30 Advanced Fuel Economy is engineered for gasoline engine vehicles but it does meet API CF which exceeds API CD.  For maximum protection, we recommend you switch to the diesel engine oil suggested by the website.
