What's the best oil for a old tired engine?
So I just got this 74 Custom/10 and I want to replace all the fluids and I was wondering what would be the best oil for an old and tired 350?
I don't know how many miles are on this engine and I believe it to be the original 350 2bbl I just want as much life out of it as possible.
I live In eastern Arizona and rarely see outside temps over 90 degrees in the summer and it got to 16 below last winter.
