There seems to be limited talk about the regular Purolator air filter on here. I hear about the PureOne filters, but not the regular ones. However, I did read some users experiencing a drop in fuel economy. Can anyone comment on this or anything about the regular Purolator air filters?
I may have been involved in the "users experiencing a drop in frul economy" that you mentioned above about the regular Purolator Air Filter.
This has never happened to me in the past when using PuroAirFilts. Although, on my 04 Nissan Altima 2.5 S, I purchanced a regular P.A.F and noticed an instant drop in MPG and, it was summer time when I get the best MPG with any vehicle! I kept the stock Nissan air filter because it wasn't really too bad to begin with. I swapped out the Puro and put back in the factory Nissan air filter and the MPG came back up. The MPG drop was about 2 MPG. I can't explain this with the exception that the Puro has less pleats and it's I.D. is more closed in(more framming aroung the media).
I still have both air filters along with a FRAM AIR HOG that I bought for $7.00 on close out at PB's (only 1 remaining) and I wasn't looking for an air filter.
I tried switching both the regular Puro and the factory Nissan from time to time and I consistantly loose about 2 MPG with the Puro. I do the switching in the summer time when I can get some real MPG figures.
I've used Puro air filters in many vehicles over the years and have never noticed the drop in MPG. I really don't notice the drop in MPG with any air filter for that matter. No gain either! I also check my MPG on a regular basis and have for many years.
Maybe I just cought a bad Puro or a not an ideal filter for my application.
