Napa brand oil is rebranded valvoline. Straight 30w contains no detergents, and high mileage oil does swell the seals thus causing better preformance but it also has more cleaners in it. I know at the refinery I work at, they use straight 30w in all the yard trucks (S-10s and Rangers with some F-150) and use the additive Rislone. I love Rislone and use it in everything now. It really breaks up gunk and keeps the topside clean and build up down. The flip side that is often over looked is the importance of a great filter. As someone said before,IMO Wix (also sold as napa gold) make the best filter. Better media, anti back flow valves, thicker housings, and better seals. Plus when compared to Pep Boys filters, they aren't really that much more expensive.
When it comes to selecting oil, just check out the API rating and compare with what your running now. In CA the EPA regulates so much that the oils are all rated almost the same. It kinda comes down to which brand your loyal to.
I actually work at Napa an my dad was the Napa Filters Sales Rep for the Southeastern Region of the US. The Napa Gold filter is an extremely good filter, but we just came out with an even better one called the Platinum. This filter is made especially for people who run synthetic oils an do the extended drain intervals. The Platinum filter has a synthetic filter media an silicone anti-drain back valve an all silicone seals an gaskets. I've been running this filter with mobile one since day one with my car. An as someone also said Napa Oil is repackaged Valvoline Oil!!!! Not the exact same but made by the same manufacture.
