you will get alot of different replys on this as for brand of oil and weight IMO I would use the manufacturer recommended weight and buy moble 1 syn -- as for the oil filter alot of people use the stock motorcrafts don't know the PN though :beer:

I used Moble 1 Sys. in my last Cobra. I am switching to that on my next oil change.

Any brand of synthetic will lubricate better than organic oil. Mobil 1 is usually available in the same viscosity as stock [5W20] so that's what I use.

 

[CobraBob]

Doesn't Ford use a synthetic blend? So you're going from a blend to full synthetic. I used both Mobil 1 and Redline. Mobil 1 is easier to get and sometimes can be bought at a discount. Even Costco and BJ sells Mobil 1 but not always the weight you need. My choice would be Mobil 1, and stick to the recommended weight.

My car has 5W30 Royal Purple in it from the dealer I got it from... no problems so far.

Mobil 1 5-30. can buy it at walmart in the big jug for pretty cheap.

I run a motorcraft filter (like oem)

change oil every 5,000 miles.

run an oil separator and clean it out every 1,000 miles

I run 5 quarts 5w30 mobil 1 and one quart of lucas synthetic oil stabilizer. Seems to work great. The car seemed to run smoother with the lucas in there. Alot of guys will try and tell you the lucas is snake oil (no pun intended). However I have been running it for 30k and have had no problems at all.

just out of curiousity--what does the lucas oil stablizer do for the synthetic oil/motor

Do not use any additives, I use Mobil 1 SYN 5/30. You will find about 80% of people on this board use 5/30 weight on this board per the last POLL. Next time I will use 6 1/2 quarts like my brother did, his heads were a little noisy and now they are quiet.

Mobil 1 5W20 here

:beer: Switched to Mobil 1 5w30 at 5,000 miles have 15,000 miles now no problems. Motorcraft oil filter part # is 820s.

 

[spinscan]

Amsoil S2000 0w30 and either Motorcraft or Amsoil filter

I use Mobil 1 and a mobil 1 filter (autozone had a deal, 5qts and a filter for 29.99, and the dude there gave me the 6th qt for free. I have a oil separator too.. just be careful with it tho, dont over use the teflon tape!
