Perhaps I should have connected the dots, but in the case of the Supertech filters it makes sense to stock them, if only for the fact that I have scoured at least 8 WalMarts and at least 3 in different states and the restocking effort is almost non existent.(I didn't go into 7 of them for that particular reason, but being has how I had to go there.. a side trip to the auto dept!?)
So like in the case of a Mobil One filter (for Corolla.Civic) they can cost up to 10 dollars. (a very fine quality filter I might add) Contrast that with the Supertech filter at 2 dollars. Are you really getting a filter that is 5 x's better, from a performance point of view? For my 2 cents, NO! Even if you are getting a filter 5x better, what or how does that statistically matter!? Of course under what conditions etc etc. Even on this august thread, from a statistical point of view the case has not been statistically established. Also the issue is really the fact that oil filters are really a "commodity". Marketing efforts of course will focus on differentiation.
So that you can tell where I am coming from, I use Mobil One 5w30 in three of my current vehicles WITH 15,000 mile oil and FILTER change intervals. (OCI's) 2 Toyota Landcruisers, 1 Corvette Z06.
On a VW Jetta TDI, I use Delvac One 5w40 aka Mobil One 5w40 Truck & SUV. WITH 15,000-20,000 mile oci's . After break in and warranty miles of 36,000 miles on a Honda Civic, will do 15,000-20,000 mile OCI's with Mobil One 0w20.
