Oil filter Motorcraft or Mobil

it was the Oil filter cartridge o ring that had become hard and did not compress to seal the filter any longer. Getting the new one, a mobile 1 filter, I could immediately tell the difference. the new one was pliable and I could tell it would seal nicely. it did...no more leak. The car also had developed a slight stutter at idle. very sensitive, these cars. the stutter is gone too.

So glad I found this post! I was getting the low oil pressure warning on my 2012 Passat. It would go away after the car warmed up. I changed the oil, dropped the oil pan and cleaned it and the pickup tube. They were already in really good shape. I changed the oil filter too of course. Anyway the light isn't coming on at all now.

I've used the spec Motorcraft filter (820S), and Motorcraft 5w20 synthetic oil EVERY TIME. This truck has been an absolute beast, and dead nuts reliable.

I ran Mobil 1 filters on my '05 Xterra because I picked up several M1 oil change specials at one of the parts stores and found the truck sounded better at idle so I kept using them.

Mobil 1 M1-108's for the Infiniti/my wife's Legacy. And the Extended Performance oil along with it. Been doing slightly extended drain intervals on multiple vehicles for close to 15 years with no ill effects. Valvetrains are exceptionally clean on any of the previous vehicles where i've pulled the covers.

I have recently switched back from a K&N to a Mobile 1 oil filter. It seems to be better no ticking noise.

Personally I run synthetic oil 7000 miles(I have had it tested at Blackstone labs and the results show it's still good at that time) before I change it and I change it and the filter(very important) at that time.

I'd like to add that the oil pressure appeared normal after installing the Mobile 1 filter. The Mobile 1 filter is about half an inch longer than the RE filter, and I read that different sized oil filters can cause the oil pressure to drop, but my indicator was not lit during any of my test riding.

I searched the web far and wide, and there are zero specs on the RE oil filter---anywhere. So, I went to Walmart and brought the old RE filter with me, and compared it to several different sizes available at the store. I settled on the Mobil 1 M1-107A. The thread shaft width and gasket diameter seem to be an exact match, and it seemed to screw on perfectly. I changed the oil and filter, warmed it up, and took a short ride around town. Nothing leaking so far, engine seems to be performing and sounding right. I'm not sure if it was just my imagination or not, but it seemed to achieve greater speeds this time around while at lower RPMs.

I've been using mobile 1 5w30 with mobile 1 filter.
