GLLubricants has Mobil1 5w-30 ESP for $13.50/L. It's 504/507 approved but according to exxonmobil it "is of 506.01 quality level".
5W-30 Synthetic Oil | Mobil 1â„¢ ESP Formula 5W-30
506.01 has higher levels of unobtanium for the cams or fuel pump follower doesn't it?
I'm assuming 507.00 isn't suitable for your application as 507.00 superceded 506.01 for many of the diesel engines?
Here's a block diagram that implies 507.00 is OK but I know there's an exeption.
/thinks.... mandatory in the v10 diesel with dpf?
