Hate to disagree, but there are some things much better than oils, etc.
The secret is now out but long was not: Often the poor engine suffered that agonies of the damned. Why? Too much gas and water got into the oil, ruined the lubricating qualities of the oil, and made the engine wear out much faster. The worst situation was running the engine cold in cold weather. In particular there was that little device, the "choke": It's job was to flood in lots of excess gas hoping to get an explosive mixture from the cold air. Well, a lot of that gas didn't burn, got past the piston rings into the oil. Similarly for water from condensation.
The big step up was to have some exhaust flow under the intake manifold to heat the incoming fuel-air mixture to do better vaporizing the gas and need less extra gas from the choke.
What solved that was fuel injection, in various forms, throttle body, port, and cylinder. Then the pressure on the gas was high enough to get good vaporization.
Next biggie was spark timing: Usually it was far from where it should be again causing inefficient combustion and gas and water in the oil.
One of the most critical needs for lubrication was the rocker arms, e.g., where the rocker arm was pushed on by the push rod from the lifter on the camshaft. On a classic small block Chevy, I had a push rod go through rocker arm and the valve cover! We got a new, 'crate', engine via Chevy.
