My F150 is currently in the shop getting a new Ford Long block. I bought the truck with 97K and a good history but this stuff happens! Very happy I purchased a powertrain warranty on it. Based on some recommendations from both this board as well as Ford techs(one of which is Fordtechmakuloco on YT), I will not be running 5w20. Most of the recommendations seem to be for 5w30.
My question is should I stick with a Syn 5w30 or something like M1 0w40? Any benefit in these 3 valves with the 0w40? Not trying to start a viscosity war here, just curious what some of your guys thoughts are or if anyone has experience with these motors? This motor failed at 103K, so I'm hoping to at least get another 100-150K out of her before it's retired.
Thanks for the feedback
