Hi there:

Although full synthetic oils have many benefits, they’re not always the best solution to use; especially on older engines. Depending on how many miles are on your engine, or if it’s been recently rebuilt will determine what type of oil you should use for maximum lubrication. My oil of choice for older engines is using a standard 10W30 or 10W40 Valvoline conventional oil combined with a rather new metal treatment called Mettle Plus by CleanBoost. If you’re familiar with the older "Moly-based oils", and how they actually penetrate on the surface of the metal, this is essentially a tri-moly additive. I believe you can get them at Fastenal locations or order online. This product works great on all internal combustion engines; but not to be used in hydraulic based units like transmissions.
