Yeah Red91 I have run the Havoline Pro DS in the Altima. It has run very well in there in terms of quietness, gas mileage maintaining well, and performance. It has run just about as good as Pennzoil Ultra and Castrol gold bottle. So, to me it really is a very good oil for the money. I will have to add that the Castrol Magnatec ran really well in the car too. Now, I haven't sent any UOAs off for analysis. But I am not trying to extend a run for a very long interval either. If I were to run 7k miles plus then I would definitely do that. Due to how much the VQ35 likes to chew up oil viscosity aggressively.
Yep car51 the Quaker State Ultimate Durability carries both certifications. Which is pretty good obviously.
