i have recently purchased a 2004 crown vic police interceptor with the 4.6l & 145,000 km. I would like to know what you all think would be a good oil to run? I was thinking m1 5w20 or gc 0w30?

one other thing, this may sound crazy but i will ask anyway. i recently did and oil change on the car, the oil was clean but i noticed that there was a honeywell defence oil filter and i could not have that. i changed the oil with gtx 5w20 and an fl820-s, and the outside temp was around -5c. I put in oil that had been sitting in my unheated garage and when i started it after the change i heard some knocking. do you all think i did some damage?

thanks in advance
nick

The motor will knock until the filter fills up if you did not pre-charge it before installation. I always pre-charge my filters. The easy ones are the nearly verticle filters, 3.8L V6, I can get a good amount of oil in them. The nearly horizontal ones such as on the 4.6L and 5.4L V8s won't hold as much oil, however, the more you can get into the filter the better, or, the shorter the knock period.

Any SM rated 5w20 will serve that engine well. I use Pennzoil Platinum in my 4.6 modular, have a 10,000+ UOA that will be back any day...watch for it in the UOA section. The FL820S is THE filter to get. Can't beat it for 3.38 at Walmart every day.
Edit: Oh, yeah, the slight knocking for a couple of seconds is "normal" after an oil change. If it does it at other times...not normal.

Is it a six quart sump? The non-police models are, so...
I'm using Schaeffer's 5w20 in an '03. Smooth. No UOAs yet.

I should have said SOME of the non-police models are, so that may explain the knock. I think the other posters are correct though, about pre-filling the oil filter to prevent it.

That knock may have been due to a dry oil filter. Keep using the Motorcraft 820 filter - or any other with a silicone ADBV.

My previous car had a huge filter, and at each oil change (approx every 2500 miles) it would knock pretty loud for 2 or 3 seconds until the filter got filled as i never have pre-filled my filters.

It did this for over 200,000 miles and it never caused a problem. I still dont pre-fill filters, and my new car knocks for a second or two after the oil change (although not as much) but so far no problems.

It's my opinion people worry too much about pre-filling filters. Then again, i worry too much about other things so who am i to talk ;\)

You need to use the motorcraft filter on that motor.

Anything else is going to knock.

I've used them all on 4.6 motors, stick with the oem filter from walmart. Its very cheap.

Thanks for the replys...the reason i was asking about the start up knock after the oil change was because the oil i used had been sitting in my unheated garage and the temp was around -5c and i noticed that the oil was slower to pour in and i thought that i may have done damage......between m1 5w20 and gc 0w30 which one would you all pick?

5w20. I've used 0w30 in a car before, it's WAY thicker than needed. This engine will run over 250,000 miles with no problem with standard 5w20.

No. -5C is good oil change temp. Seriously, there is no way you did any damage.

Use the M1 5W-20. Although GC is a very good oil, it's a bit thick for the Ford modular motors.

Agreed.
