View Full Version : Yet another oil question....

And I searched but couldn't find a definitive answer.

I just bought some Mobil 1 synthetic 5w40 oil for my A4 but it's labeled "Truck and SUV". Can I use this oil?

Havent seen that oil yet, but Castrol Syntec labels their 5w40 as "European spec" oil. Diddo on Mobil1's 0w40 (I run both, and they work wonderfully).

Thanks TBM- next time I will look into one
of them.

Does anyone have a definitive answer for me?

only the weight matters, and 5w40 is the right weight, so, its fine

Yea, i have been thinking of using 5w40 durring the summer, but I have 0w40 in my car right now The quick start power of 0w40 is nice, but i do worrie about start protection of the engine.

mobil has been making alternate synth blends lately, what you picked up might be one of those. the fact that it is for trucks/suv tips this off.
