I won't lie, I not only use Motorcraft because its the Ford brand, but I also use it because its cheap! Between the oil/filter with a shop discount() my oil changes run me about $25. When I first got the car I would take it to the dealer and pay the $40 to have it done which is still cheaper than most places around here. But now since I just do it myself(I love lifts, they make life wonderful) its less than a full tank of 91.

 

I hope you guys running long oil intervals that drive hard are using a catch can or valve cover breathers.

Also if you drive hard, 1/4 mile it, or feel you could rationalize an upgraded windage tray, you want a filter that flows freely, not one that filters a lot. In that regard a new filter will work better for you than a "broken in" one.... The danger of bad filters is when they stop flowing.... Cause even dirty oil in that instance will be better than no oil....

That report from Bob The Oil Filter Guy is great. Heard too many stories of people's engines grenading from a filter that loses it's guts and stops filtering. Now I always buy Motorcraft because the company that's on the label also happens to make the motor the filter is installed in.

 

The filter will not quit flowing because it gets dirty, that's what the bypass valve is for. As you say, dirty oil is better than no oil.

 

motorcraft for me too

 

define long intervals please.

 

True, but only if the bypass valve works. Read that report from Bob The Oil Filter Guy. Apparently there's quite a few designs out there made from cheap materials that it's suspect if the valve would operate if the filter itself was dirty enough to be clogged.

 

That's a good reason to only use the Motorcraft filter. You know it is high quality and made with the best materials.
