Depends on leaks and relative wear. If no leaks and compression iss good then 10-30 Mobile 1 if oil pressure is low or mor wear then 15-50 Mobil 1

I use the the Castrol 20W50 blend for cars over 75,000 miles. My '88 just turned 157,000 miles and burns less than 1 qt. each 3000 miles between oil changes. I can live with that. It runs great and no leaks.

I just saw a thing on tv about Royal Purple

Supposedly it works great. It dyno'd +10hp out of a 500hp motor. Royal Purple also has a Dextron-type blend and a gearbox fluid as well.

Oh, I might mention that all fuids (engine, tranny, pumpkin) were swapped with RP in that engine.
