Drain valves versus plugs versus suction

[mike]

Not entirely true...depends on the contaminant in the
oil

1. Contaminant is chemical (acids etc) .....filter is
going to do next to nothing... so change the oil more
often

2. Contaminant is physical (swarf etc)....change the
filter more often.

I suppose car oil is somewhere between the two
extremes..myself i always change both at the same
time.
