here's something for high mileage honda drivers - engine clatter on startup is pretty much to be expected on a honda. or so i thought. but doing some filter spec homework, i find that there are oversized filters available that will fit b, d, f, & h series engines, and when used on my high mileage d and f series engines, make their cold start noise almost disappear.
it would seem that less flow resistance [due to larger filter media area] allows sufficient oil flow to occur even with the oil cold. it's an immediate and very noticeable transformation.
anyway, i put it out there fwiw. the filter is wix 51344. it's used on industrial isuzu and mitsubishi engines. i'm sure other manufacturer equivalents will work just fine too - with the usual proviso about manufacturer quality.
