Owner's manual for a 110 300TDI says to use an ACEA B2 oil in 10w40, and if that's not available to use an ACEA B3 oil (since ACEA B2 has been superseeded).
I already stock 3 different kinds of oil for our current cars:
Motul 8100 X-cess 5w40 an ACEA B3 oil
Castrol Motorsport 10w60 - no ACEA rating on the bottle plus I don't think I could use this in a 300TDI as its probably too thick
Mobil 1 15w50 an ACEA B3 oil
Could I use the Mobil 1 15w50 in the 300TDI?
The car I currently use the 15w50 in can also use Mobil 1 Turbo Diesel Truck 5w40 which is a ACEA E7 oil. Is it ok to run this oil in the 300TDI?
Just trying to reduce the sheer variety of oils sitting on my garage shelves. Thanks in advance for any and all advice!
