How does one compare a new filter from one company vs a used filter from another?
I just showed them since I had them. I thought the difference in pleat amount was interesting. Plus the metal cap vs plastic and the rubber end gaskets.
Answer-BOTH!
Interesting to see modern metal endcaps on a cartridge oil filter. I bet the Ultra has better flow through those wide open synthetic media pleats than the M1’s tiny holes! Not that it likely matters anyway.
Sometimes it is not about saving money, it is about using something for it's full potential (and at 10,000 miles, it can be argued a Fram Ultra still has a lot of life left in it), and/or convenience factor (some filters are much harder to change than others).
Plenty of holes in the M1 center tube. There might be a very slight increase in delta-p on the M1 center tube compared to the Ultra, but the PD oil pump doesn't care.
Mobil 1 HM for both 5,000 mile changes.Looks good! Thank you for posting
What kind of oil did you use?
You're alluding to a neglected potential problem of cartridges that have rigid plastic end caps, including but not limited to Fram models. If the relevant surface of the end caps aren't perfectly flat (assuming the mating surfaces of the filter housing are flat) and accurately aligned, oil will bypass around the end cap.
Me too.I'm still waiting for someone to prove with an official study that dirtier oil makes an engine wear the same or less and stay healthier longer than cleaner oil.
No one is going to try to do that. It’s not common sense. Dirtier is the main misrepresented word, is it really dirtier in real use? How much? Still waiting for particle count tests that show which full flow is actually best under real world conditions. We already have the Frantz test well established as something definite. Some pc tests have been posted, nothing really shows anything outstanding yet. Which is why the Frantz was invented in the first place way back when.I'm still waiting for someone to prove with an official study that dirtier oil makes an engine wear the same or less and stay healthier longer than cleaner oil.
There is virtually no such thing as a "real world" test. Way too many variables to control and the results usually come out as being statistically invalid. Have you ever worked in a testing environment where obtaining valid results is important?
Yeah, nobody is going to do that because they will never find a study that doesn't say that cleaner oil results in less engine wear.
Does this include the no name filter used on the same car that beat the Fram Ultra? Or is that one covered with excuses already?I know it is, and it’s Blackstone musta made a mistake. Is there another newer excuse the result is not good??
