Now let’s talk oil filters. The chart above corespondents to some research I did on my own in January while preparing to change my NGT oil myself. If you inquire with your concierge or dealer, a different part number has been assigned to the Ford part FL500S oil filter when applicable to the NGT. (Unfortunately I don’t have the filter part number handy now) It’s another way of restricting access to the part, as other retailers cannot get the part or sell the part, it must go through the concierge and servicing dealer. Cost is around $72. I know because my dealer sold me one. My independent homework revealed that at least from what I gathered, the oil filter number FL500S was indeed the same identical filter as the one the dealer sold me. I just purchased that filter (FL500S) on Amazon for $4.87. It’s interesting to me that now the official Motorcraft cross reference chart calls for FL500S for the new GT. Isn’t marketing and pricing strategy an interesting thing to contemplate? I have not seen nor run test data on flow rates, filter range, etc., I wonder if anyone else here can share their experience and research. In the end, I can change my own oil on my NGT for about $100 using my lift in less than an hour. Huh? Maybe when my car’s engine explodes into oblivion because I am so cheap, I will better understand the rationale of paying more.....However, I don’t anticipate that will happen.
