oil change lol
true, but the cat engine is also much larger, so by scale its the same thing as filling/not filling your filter on your magnum, in theory.
two questions, and a third maybe less or more important depending on your train of thought about the cat/magnum relation (i assume everyone knows or can search for the magnums) 1) cat engine displacement vs. magnum? 2) cat oil capacity vs magnum? 3) physical size of cat motor compared to magnum. if they are roughly the same by scale, id say fill your filter... though i do anyway at least on most v8s its not a huge PITA.
and are you positive its not
pan->filter->pump->engine compontents->pan?
i dont know and was wondering myself.

You're funny. How do you think the oil gets up into the filter? Magic fairy dust maybe? (Just messing with ya, don't get pissed.) The filter sits above the pan. The only thing reaching down to the bottom of the pan would be the oil pump pick up tube.
The Filter on a dry sump system is located between the pan and the filter isnt it??? It makes sense to do it that way atleast, cause that way anything that the strainer on the pick up tube misses the filter would catch before it went into your pump???
But in reality the engine is not dry anyway. I dunno about anyone else, but when I change my oil, it only takes me a few minutes. I drain it out, take off filter, reinstall filter, refill and run. On a slow day it may take me 10 minutes. The engine is still lined with a good film of oil. It should not really experience any friction or heat build up for those 2 seconds. I don't let my engine drain for an hour or more.
On our vehicles, it is so easy to do that I don't see why anyone would recommend not to.
If it was a nightmare to get to, and/or installed horizontally, then I'd say no, don't bother.
I agree, not doing it is unlikely to cause any problems, since oil changes aren't supposed to happen all that often - Its more of a matter of perfectionists doing everything possible to baby their vehicle.
Priming an internal high pressure fluid part is mandatory in some cases, preferable in others ,,, In this case, optional.
I think everyone would agree it personal preference weather or not to fill your filter. But just for sh*ts and gigs i got my Haynes manual out and looked to see what the had to say:
Direct quote Chapter 1 Tune up and routine Maintenance page 13
"18 Apply light Coat of clean oil to the rubber gasket on the new oil filter
19 Attach the new filter to the engine, following the tightening directions printed on the filter canister or packing box. Most fiter manufacturers recommend against using a filter wrench due to the possibility of over tightening and damage to the seal.
etc etc etc...
24 run the engine for only about a minute and then shut it off. Immediately look under the vehicle and check for leaks at the oil pan drain plug and around the oil filter.
25 With the new oil circulated and the filter now completely full, recheck the level on the dipstick and add more oil as necessary."

700DollarDodge, i looked up the oiling system in the book while i was at it too, it didn't have much to say but from the way the oil pump is set up i would say it is
Pan->Pump->Filter->Engine Components->pan
the pick up tube runs straight into the pump and i don't see any way oil could go around it and not through it.

Note that you're only "dry starting" the engine once each oil change. If you run the engine hot before you dump and then change the oil and filter you've still got lube on the rod and crank bearings as well as the cam, and it should be a moot point anyway.
Funny that there's 7 pages on changing oil though. Guess everybody feels qualified to comment on this one, LOL.
