My new ride came with an oil filter. Last I checked they all did (at least I think so). Being a mechanic and design engineer I can confidently say that's what that gizmo is there for.

As for all the rocks floating around in yer engine downstream of the filter, if running the motor doesn't flush em out, then just draining the oil won't either. In other words, change the oil as often as you like (so you can sleep at night) but don't exceed the recommended service intrevals.

The magnet on the drain plug is there as a secondary "catch-all" for (heaven forbid) large ferrous objects that may end up in the crankcase and hold them until the next oil change. During an oil change it's normal to occassionally find very small filings and / or metal dust (so to speak) on the plug. The engine uses a pressurized oil system and all oil supplied is filtered such any debris in the engine case and sump should not result in damage from dirty oil being supplied.

In saying that, what does take a beating are the two oil pumps. Any debris in the case has to first pass thru the scavange pump then the main oil supply pump to then be passed on and collected in the filter. Of course if these two parts become damaged from large debris then... well you can easily figure out the possibilities.

Yo Alien,

We're both on the same page here. You're also right that some of us (me mostly) didn't read backwards far enough and think 'bout what and where you where coming from.

I've always admitted that sometimes, which is most of the time, I'm just smart enough to be dangerous.
