Again, this is just a guess - I've never read anything > about this. I am confident that the oil pressure pick-up point is after the filter. Therefore a restrictive filter can only reduce the measured pressure, not increase it. Ed

Same problem. Changed to NAPA best filter ( I think this is made by Wix) Problem solved. WW

But in the Consumer Reports test, Fram (and Lee Maxifilter - Champion) did even better and was not only top rated but also check rated, meaning they did significantly better than the rest. They removed something like 88% of the test particles (I think they were 20 or 25 micron particles, but I don't remember if the test was single-pass or multi-pass), compared to 70% or 75% for AC. The worst filter removed 50%, and I think it was a depth filter.

The worst filter removed > 50%, and I think it was a depth filter.- Hide quoted text - > > - Show quoted text - Doesn't matter how well it filters if the ADBV doesn't work, and Fram's traditionally don't. NB: I haven't used a Fram filter in 15 years or more because of this issue, so they may have rectified it - but why take the chance when so many other filters have been working well for years? nate |
