all conventional 5w20 is what is called group 2+, meaning it didn't come out of the ground that way, but not processed enough (heat, temp etc) to be called a group 3. All conventional 5w20 SM oils are excellent oils. Pennzoil has the art of making a first class oil down to a science. For the utmost, buy Pennzoil full synthetic, for ultra long OCI, 10,000k or more. If you change UR oil every 5000k, then conventional oil will work exactly the same.

Pennzoil conventional will work fine for 7500 mile intervals. It's a Group II+ oil from what I've heard, so I don't think it's a blend.
