221 V8 Engine Oil Recommendation

[JM 35 Sedan]

Welcome to Fordbarn. Very nice looking '36 PU. Oil preference here is a never ending discussion. You can read every previous post on the topic and still not have a conclusion. The Shell Rotella T 15-40w is what I use in my old and modern vehicles. I put a lot of miles on my vehicles, and all is well with these engines, so I will keep using this oil until someone can prove to me there is something better.
