1999 Grand Marquis 190,000 miles.
5w30 Mobil 5000. Change every 5000 miles.
OCOD knock-off filter. I think I got it at O'Reilly's during a Mobil Super 5000 sale.
Out: 5w30 G-Oil/10w40 MSHM with a Fram HM3600 filter
Miles on oil: 2,126 miles. Apologies to DN3.
What can I say? I have a boatload of oil and I gotta use it!
In: 3 quarts of Valvoline Nextgen HM 10w-40 + 1 quart of G-Oil 5w30 and a Motorcraft FL-400s
I took the car for a spin and so far I love it. Maybe there is magic in the Motorcraft filters after all.
Out: Mobil 1 0w40 & Mahle filter after 3691 miles.
In: Mobil 1 0w40 & Mann filter
I changed the oil because I found the airbox cover wasn't screwed down tight and may have been leaking. The threads for the screws are just in the plastic and it was stripped out. I fixed it by using a larger diameter screw.
