Mobile 1 5-20 and either Mobile 1 or K&N filter.... whatever is in stock at the time.

 

neither could I.....amazon came through though.....

link to the full set for Fords>>>

 

Yeah I need one as the S331 rad hose gets in the way of the filter and it's a pain to loosen with a CAT filter wrench.

Am just gonna hand the number over to my friendly NAPA Rep.

 

I use the full set all the time....comes in handy on some of the models that use these different size filters on.....hopefully your guy at napa can get you one......cheers

 

I do exactly as Ford tells me. Motorcraft 5W-20 with a Motorcraft FL-400S filter. All others are crap

 

The recommended Motorcraft blend and the FL820 filter. I'm well over a quarter million miles. Engine still runs very strong and doesn't loose any oil between changes.

 

Whatever the dealership puts in it.

 

Motorcraft 5W20 synthetic blend and Motorcraft filter

 

Castrol 10-40 and a fram filter

 

Supertech 20w 50 and a fram filter

 

Valvoline 10-30, MC filter @ 2,500 interval.

 

I think it depends on the mileage of the truck as to what you should use.

My 98 has 376, 000 kms. I use 10W30 in summer and 5W 30 in winter. (gets cold up here lol)

As for brand it never really used to matter but I recently switched to penzoil (about 3 or 4 oil changes ago) as I here less negative things about it and I got a super deal on it so I stocked up on it. I don't think brand really matters but the penzoil seems to stay cleaner longer then all the others I tried.

I always used a fram filter until my last oil change when I switched to MC. soo much quieter now. I will never go back- its cheaper too .

Also change every 5000kms, no sooner. I went 10, 000kms once due to some other issues non truck related (between 350 000 to 360,000kms) and I got very lucky with nothing going wrong. I wouldn't recommend it though.

 

I run Castrol 10W30 and lucas oil stabilizer at least every other time I change the oil.

 

Royal Purple 5w-20 and K&N filter

 

did you put the stickers on the back window for more power?
