Only 11 years? Fooey. If MTBF (Mean Time Between Failures) of every
part on the car was 11 years, you would be fixing something that
failed almost daily. I want parts that will last 50 years or more.
That is a very critical part with severe consequences when it
fails. When the oil is lost the crankshaft bearings may go away
before you hear the loud knocking noises, by which time it is too
late and very expensive to repair the damaged crankshaft.
Go for the Teflon lined hose.
