mobil 1 5w40 is availble at walmart. it has the latest compression engine label. all it is is a repackaged mobil delvac 1. its the same exact product but called mobil 1 truck and suv formula to target the average consumer.

 

I thought it was kind of funny that the Delvac costs more than the normal M1 15w50 oil. Either way I'm switching to either that or Amsoil 15w40 next oil change.

Yea it leaks, it's german. (in process of fixing several leaks)
