Brings back memories of my first restoration project, back in the '60s -- a 1943 Willys Jeep. An occasionally refreshed roll of toilet paper kept her running.I'm trying to find the one that J.C. Whitney (Warshawsky's) used to sell that uses a roll of toilet paper.......for real.
I'm a Mobil 1 filters as well, but the big issue is using a synthetic medium when the intervals are as long as 10K. The paper filters will break down over that time. I haven't cut a filter apart in 30 years, but the old Wiks didn't have enough holes in the center tube, which causes a larger pressure drop across the filter than is necessary (causes more oil to bypass the filter). I don't know whether they ever got around to changing that or not.I normally use Mobil1 but I keep back up Wix filters in stock at home. The Wix air filters I have used lately are Made in China. A big let down . Smart has been around long enough now for them to make them. I also use Wix cabin filters.
Yor point us well-taken but I have no data to the contrary. I know even back then they wre highly thouht of. At the same time we cut open a Fram. It acrually had rusr on rhe inside! Are they still like that? I dont know but I saw enough and Ive never bought one since. Anyway, that is why I included the caveat.Wix makes many different store brand oil filters and is, today, considered one of the better filters made. Don't base your decision on a 30 year old experience.
this would coincide with our original finding which was there was a large pressure drop across the filter due to insufficient number of holes in the center support and a bypass spring that was set on the high side.Just wanna post an update since I found a Wix mentioned here.
I have been using OE Oil filters and Mobil 1 M108 for a while. My latest oil change was with a Wix 57040 oil filter.
First major observation. Oil pressure at hot idle is LOW, ~ 5psi. I have a a SPA Technique gauge installed for a while. Never had the pressure this low before and this is the only thing that has changed since the last oil change. May swap out back to OE filter to see if it goes away.
