The new Nissan oil filters are made in Mexico by Gonher. They will not give any information concerning efficiency or any other specs. I tried the Nissan shorty filter for my Altima and started getting a startup tick for a couple of seconds each morning. I thought it might be cold weather related so I replaced that new filter with the other new shorty Nissan filter I had. This too gave some startup ticking noise, although not as often or as long per episode.
I then went out and purchased a Fram Toughguard 6607 oil filter and have not had any noticeable startup tick as of yet. I do know the silicone ADBV on the Nissan filter is less rigid than that of the Toughguard. I am surprised by the outcome of this experience, but I have used the Toughguard 6607 before on my Altima and also my Frontier and have had very very little, if any, startup tick from the Toughguard. I did try the Fram Ultra 6607 once and did have some startup tick with that filter though. I do not understand that, since I understand the full synthetic oil filter is supposed to flow better than the semi-synthetic Toughguard.
I can understand some noise from 1 defective Nissan filter, but not 2 in a row. I have lost my confidence in OEM Nissan filters. That's for sure. I think I will stay with the Toughguard. Any thoughts out there?
