Not to mention if you really look at these stats vs. 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. 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. if you have the gold and the pro select filters off of the Napa website, have the exact same dimentions of everything. cutting cost everywhere even if it hurts them.Where does this information come from. Needless to say there are only 3 napa's left in town now and the owners son is running it into the ground. "well it looks like you succeeding so where gonna get rid of some counter guys and delivery people." all because he walked in on a holiday and saw a couple of them standing around. thats not even enough to keep the utilites going and pay one stores staff nevermind all 5 stores then they took out the paint mixing booth and the machine shop.īefore this all started to happen i was bringing in easily a $500,000 a month split between my sales and counter staff. ensuring once again even if you where retail if you wanted anything from me your gonna wait. then extended our hours and fired my other counter guy. ensuring that if you wanted anything from me it would be 2 hours before it got there. then corporate came in and halved my the amount delivery drivers i had. I used to work for napa for years and loved it.
