what I am suggesting is that since they are the sponsor, and they are reviewing their filters. Yeah I seen that, but what I am saying is that it is sponsored by Napa/Wix. Here is purolator one filtration standards- thier basic filter:īTW, here are the P1's official, and excellent, filtration specs: Yeah it might read 98% filtration, but that would be on size 15+ particles. and how mis-leading some filters can read.
PROSELECT OIL FILTERS HOW TO
This is the oil filter review section off of another site that gets into how to compare the filters. The larger the particles that get through the filter, the more damaging they are to your engine, I can't overstate this enough Whatever you do, make sure the micron rating on whatever filter you choose is no more then 10-20 microns (10 is optimal). I would make sure the micron ratings is over 50% at 10 microns. The micron rating gives you an idea of what size particles are permitted to pass through the filter. The best filters are up around 98-99% single pass efficiency and up to 96-98% multiple pass efficiency. That is why multiple-pass efficiency is a better measurement. Unfortunately, single-pass testing doesn't measure a filter's ability to protect your engine under actual driving conditions, where contaminated oil passes through the filter again and again over thousands of miles.
Single-pass efficiency measures a filter's ability to remove contaminants on a single pass through the filter. If you want to grade oil filters yourself, there are three main criteria: single-pass efficiency, multiple-pass efficiency, and micron rating for particle pass-through.
It don't matter to me on either of these, i use puralator gold, but just spent some time with a good search for oil filter review to find some commonalities to confirm that the napa/wix isn't the filters to get, based on partical size filtration.īest Oil Filter – Reviews and Rankings | Bestcovery Only thing different is the description of the features and benefits, which they would have to have something different to justify the cost increase.
PROSELECT OIL FILTERS PRO
if you have the gold and the pro select filters off of the Napa website, have the exact same dimentions of everything. Reassuring in the light that River Rat reported some leaky Wix filters.Where does this information come from. The Golds have been flawless despite having inspected far more of them and in much more severe service so they are what I choose to use. Yes, the findings in my case yield an alarming failure rate, hence I no longer use them and recommend against them. None of the vehicles suffered any noticeable issues and the issue certainly would have gone undetected if the filters had not been disassembled. I was quite shocked as these filters have been considered a good low cost filter option for many years here. I routinely cut every filter I remove with a purpose built filter cutter I bought some years ago from Summit. I showed the owners the filters and needless to say they were not impressed. Several of the filters were off our police cruisers (installed by an outside shop) and the rest were from coworkers vehicles. Several of the holes were an inch or more long and had been "opened up" to about a quarter of an inch wide-to the point the center tube was clearly visable from looking through the side. The failures were tears in the pleats at the folds and as noted above the media was very brittle. I can tell you they came from a variety of applications.
I did not save any of the filters in question.
