I noticed that in cold weather my n* clatters on first cold start as if the oil were low. I checked the oil and it was low so filled to fill line and still does it. Only on a cold start. This happened last winter also and it only happens in the winter. Is the 5w30 oil to thin. I used full synthetic oil at last oil change and refilled recently with mobile 1 high mileage. Since filling to fill line it has shortened the clatter time but its still there. I don't want to over fill it.

Oil is thicker at start up so weight has nothing to do with start up pressure being down for thinned oil.

What brand filter. Better not be fram... Ac delco Pf61e (my choice), Mobil 1 or k & n are proven strong with drain back protection.

All oil filters are not oil filters - read these to find out who rebrands what. FWIW, I happen to be partial to WIX or NAPA Gold - same filters and anti-drainback valves.

It should be noted that was done in 1999,

Delco changed which is why I use them, dealer (warranty) cant complain either since they use them

I had a similar sound with my 05 N*. Never fixed it but that clatter on cold start would sound like my starter sticking a second. Any starter issues in this forum?

Some brands do not have the anti-drainback valves. This is an important component for the 4.6 N*. Scrimp at your own risk.

I use very little Mobil1 between changes (a pint or less) and hope to never use anything else. Yes, it is dirty when I change it (close to 0% on the OLM). That's it's job.

Had mine replaced a few months back. Starter would make a loud click when trying to start the car, that was it. Try it a few more times and it would start up...but still that very loud click whenever it didn't start. No issues since it was replaced. Thankfully I have an extended warranty through Ford so I only paid the $100 deductible, think it was about a $700 job.
