the walmart comment about things being different has some truth to it but not with oil filters.
Mobil 1 used to (maybe still does) have a walmart specific blend for their 5 quart bottles. This was a few years back.
I use Amsoil synthetics in everything I own including my race cars and either Wix, EA or OEM filters. Wix makes napa. toyota and honda filters are phenomenal. The motorcraft ones are good but are a cellulose media. Which is good, but not for etended drain intervals. Pureolator one looks like a great readily available synthetic, long drain oil filter. The mobile 1 oil filter has the most filter media of any filter for its size ive ever tested. Going to run one of those next with amsoil synthetic at 10k on a gen 2 and do an oil analysis.
No one here is running E85 or any exotic fuels so honestly any synthetic that meets the spec will do. If you're really worried buy an oil analysis. Shit pretty much everyone is running stock turbos still. When RBM engines start popping up we can start the oil pissing matches.
