2014 F-150 with Ecoboost engoine, 12k miles on it. If they are price-equivalent, what would you put in it? MC Syn blend or PZ full syn 5/30? Both would use a FL-500S MC filter. I understand it came from the factory with the MC blend and filter and I've done 3 OC with that setup 'just because' and was according to the OLM. I have lots of short trips and a few scattered 50-75 mile trips now and then. If they are price-equivalent what would you go for? It's covered under a Ford 100k, 8 year extended warranty.
