I have my motor back from the machine shop and they recommend using Valvoline Racing Oil. Is this just an old school choice? A Fram HP1 filter was also recommended because of the higher oil pressure I'll now have.
I don't want synthetic, so being not a race motor what are some good options? and should I be using a zinc additive? It has hydrolic lifters if that helps.
As far as the filter goes, I've been using the WIX, but not the racing one, is this still OK?
