I didn’t mean to come across as completely ignorant, so here is the whole story.
I have always been partial to Purolator; I got that from my deceased dear old Papi, who during the sixties and seventies ground into my head that “the original” is the best.I have owned the car for eighteen years now. At the beginning it was my wife’s car.I always used Castrol Edge FS and a Purolator L15317. I waited for the filters to go on sale, and usually bought like six at a time,so I had a pretty good stash of them at the house. For a while there too, I did the same with the Bosch 72209. As time went on,retirement came for the both of us, and the car started to be used less frequently.At some point I decided this was going to be my First Collector Car.So the car got used even less.About eight years ago I found myself “forced” to change oil & filter every year, because that was the conventional wisdom at the time.During these 8 years the highest number of accrued miles on the car in any given year was 46 miles.So,I found myself spending around fifty dollars to replace oil and filter with forty-something miles of use.I reached out to an acquaintance of mine (a really big and renowned car collector here in Florida), who laughed at my naive-ness. He told me that he has cars in his collection that have had the same oil in the crankcase for the last 26 years, and as long as the car does not exceed 750 miles with that oil AND do not show any oil contamination (like water emulsion, rust, suspended particles, etc.) he does NOT change oil based on time alone, because oil does not spoil, separate, degrade, or otherwise go “bad” on its own.So!!!..new “collector plan” for me! Now I plan to start fresh from scratch…Give the car one oil & filter change using the best oil & filter for my specific application and go from there. Based on my age, the myriad of health issues I have been battling over the last five years and the amount of use the car gets, there is an excellent chance that I will die before the car is due for another oil change.
Now to the point of all of this…I vividly remember that back then, both, the Purolator L15317 and the Bosch 72209 filters were heavy,sturdy, big and heavy duty units.Both were stenciled with the words “Made in Germany” and to my recollection, they both looked identical. As a matter of fact, I think I remember reading somewhere that Purolator sublet the manufacture of the L15317 to Bosch. So, in pursuing my new and improved “collector plan”, recently I went shopping for my new oil filter.I was shocked when I handled the new L15317 filter at the parts store.It is light, flimsy, rattles like an empty soda can, much smaller in height and circumference and not a mention of Germany anywhere.The Bosch wasn’t any better. To begin with, the 72209 does not exist anymore. It has been replaced by the 72209WS which to me looks and feels exactly as the new L15317 does. To me neither one of them is worthy of my car. That is why I reached out to you, fellow cat owners, to see what your experience is with this issue.
