New member here. I have enjoyed learning a lot from this site, but have never thought of anything I could contribute til know so finally joined. I have searched high and low in southern Ontario for Purolator brand oil filters with no luck. I recently noticed that the Carquest Premium oil filter for my car. I use the longer version of the filter for the GM 3.8 in my Lesabre (Carquest 85036) and it looks just like photos of the Purolator ONE filter. It has the oblong slots instead of round holes above the ADBV. Although the photo on the box shows round holes. The other thing I noticed is that it makes similar efficiency claims that the Purolator ONE does and they even use a photo on the back of the Carquest package that is remarkably like that of the Purolator. Yes, I can order Purolator ONE's via Amazon.ca but they cost around $12 and up. I just got this Carquest Premium for $6.50 plus tax Canadian which I feel is a great price. In the US, the price differential may be inconsequential but up here, the Carquest is literally half the cost. Not sure if this was common knowledge, but thought I would share for anyone with less than idea access to distribution of Purolators.
