That brings to mind the valve seat, head gasket sealing, cracked blocks and valve erosion problems that are common with some specific makes lately. As a consumer of an "appliance" vehicle, I'd be quite annoyed to have unnecessary problems related to poor design or metallurgy.This is a good point. As we have seen here, some engines can't be "fixed" with the choice of oil or oil viscosity. Some engines are just not designed or manufactured well, and use inferior materials or lack good metallurgy to last as long as engines that are designed and made well.
Add in pistons, rings, chains, and oil pumps made with yesterday's quality, and operated in high temperatures with ultra thin oils, coupled with extended OCI and fuel dilution and it should be no surprise when that timing chain wears out at 100K miles or the "ultra reliable" Honda V6 engine starts consuming oil.
