I found this out when my father asked me if Platinum had that spec (which is required for his new Volvo) and I found out it did not. Now I do realize the oil PROBABLY meets the spec, but the fact that Pennzoil refuses to test the oil towards it makes me think a little bit less of them. I like the fact that Mobil 1 seems very committed to making sure it's oil is submitted for all of the testing it needs in order to pass the warranty requirements of many vehicles. That gives me much more confidence in an oil!
True, thats a good point and I feel the same way about it, I think Mobil 1 is a bit more expensive, but I would believe its a higher quality product, it would give me peace of mind.
