  •  Unless you are really putting a heavy load on the (0+ / 0-)

    engine, I am of the school of thought that a lighter oil is actually better - because it gets to engine parts sooner on startup.

    In any event, modern synthetic oils hold their viscosity much better than conventional oil. The cold pour is a lot better, and the hot thin-out is a lot less.  

    •  Lighter oil , lower pour point ? (0+ / 0-)

      A lighter oil is less of a barrier between moving parts .
      With the trend to reducing bearing size the psi is going up ?
      Thinner oil being asked to do more over a smaller area ?

      •  That's why I said- as long as you're not pulling (0+ / 0-)

        a heavy load. If you're towing a horse trailer then I suppose the heavier oil would be justified. Otherwise the light oil gets to the engine parts sooner upon cold start.

        In any event, it's rare that an engine dies because of bottom end failure. It's almost always the case that the top end craps out before the bottom end. And a lot of those failures start out as, or became critical due to overheating, and not due to lubrication failure.

        A lot of people have gotten the gospel to change and check their oil. But unfortunately most of them don't do nearly as good a job maintaining their cooling system. When you see a car by the sde of the road, most of the time it's the cooling system.

        •  The load on the bearings psi (0+ / 0-)

          has been increased in the design . Smaller surface area bearings . Its a way to decrease drag . Combine that with a thinner coating of oil ...
          And then combine that with the mandatory reductions of the high pressure wear additives ...
