Aruuuuuuuuuuuugh, how about not only French made, but in an orange box too? Both the filter that came from the factory in my 02 Cavalier and the one I paid my Chevy dealer $8 for in a box labeled AC Delco, said Purlux 264A on the inside. Later I discovered Fram was selling the same filter, Purlux number, mold numbers, and all. A month ago, I found a cheap Fram thing in the PH 9018 box instead. I tried an STP, but it looks suspiciously like the Fram thing. It is a cartridge filter with no metal housing to hide the filter media and plastic end caps.
And yes Ray, whether it needs it or not, the one I took apart and measured was 3'' wide by 46'' long giving the 138 sq in. Perhaps Mystic is going by some of my previous posts of this info. That 138 in2 is barely half what my 77 LUV gets when I find a PF1177 for it. Along with some others here, I tend to see filter area as one of those "never too much" things.
I have not seen Purlux filters sold under their own name in the limited number of stores I can shop at. I have collected the following numbers as specified for my Cavalier.
ACDelco PF2244G
Hastings LF548
Purflux L264A
Purolator L 15436
Baldwin P1445
STP S9018R
WIX 51365
I am told it does, but I am not sure the Cavalier with the Ecotec takes exactly the same oil filter as the Saturns, but I would think so. The Purlux filter has a distinctive zig zag to the pleats compressing 3'' of media into a 2 1/2'' filter. So look around. I haven't seen most of the brands listed above, and they could be as good as the Purlux.
