Liqui Moly Top Tec 4605 5W30 used here. Dexos2 and ACEA C3 rated. Fully synthetic. Love the Mobil Delvac 1 synthetic but that is not Dexos2 rated but all the other diesels on the farm use it. Might change anyway once the miles are up there and warranty is gone.

So if 4605 is C3 approved why would it not be acceptable for our engines?

Guess the folks at Liqui-Moly did not want to pay the licensing fee!
I am going to switch to Delvac 1 ESP anyways as that is what all the other diesels on the farm use.
