What kind of synthetic is Havoline 5W-40 - is it a group IV or V, or is it group III hydrocrack?
The reason I ask is because I've just done an oil change with my usual Mobil 1 0W-40 and at seven quarts at a 5,000 mile OCI I'm finally starting to notice the cost. I have access to trade pricing and the Havoline is somewhat cheaper. As always, I eagerly await your quality comments. Thanks - Ian.
