Oil filter Fram or Mobil

Frame Ultras are actually quite good. The. Orange ran frams are the ones to avoid.

I use OEM or Wix filters only, but my dad has been using fram filters for decades and swears they're fine. Most of his vehicles have over 300k miles on them when he sells them too, so it's not like he dumps them when they're out of warranty.

Fram has different types of filters, the low end ones are the ones that get trashed on, but they also have some good ones that are on par with what you'd get from any other brand. Even if you use the bad ones it'll be fine, you might want to change the oil a little sooner than normal though.

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 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.

With synthetic oil do you need a fancy filter? Since I change them very religiously, I wouldn't think it would matter. I use the FRAM filter (standard size).

Are you using a cheap generic/fram filter? If so throw it away. Oil change shops use a generic cheapie crapazoidal filter, and uses 10w30 for your car.

the bypass valve on the Mobil filter is too low for our engines ~ 15 psi. Mahle/Mann is at ~27 psi. In certain situations, even normal situations, the mobil filter isn't filtering at all

Frams are cheaper. Fram filters are smaller and don't have the same internal baffle / checks and might not filter as well. It's just not as quality of a part than other manufacturers. You get what you pay for.
