Dennis, thanks. I'll look into the Fram ToughGuard filters. I have several Mahle filters that I bought though, thinking (following advice concerning pressure drops and other shortcomings due to other filters) that they were better for our vans, and getting a better price by buying several. I do recall that the "Cheapies" that you mentioned have considerably less total membrane than some other filters do, according to a web page I reviewed some time back. I don't remember the TG filters being included in the review. I used the "Cheapies" for many years (years before the TG was offered), as they were reputed to be among the better filters available for DIY. But that changed.

Thanks again, David
