@Corvette Ed,
Yeah, I've gone on these sites that show you the differences between oil filters and which ones are better. And then they cut the filters open to show you the better filter element and which ones are doing a better job and whatnot, and Fram is at the bottom of the lists. I think the site may have been sponsored by Wix or one of those. Haven't you seen those sites looking for a good oil filter? I don't know why I use Fram, I think it goes back to when I owned a couple of my first cars, and I just picked it and it seemed to be doing a good job, as well as any other. Sometimes it's cost, sometimes it's whatever is available where I'm at at the time, out on the back roads and stop in somewhere. I know that's not caring much for the thousands of dollars of investment I have in this custom truck you'd think something as important as oil filtration would hold a higher priority with me than it does.
Some of it is how far I'd have to drive to get some special filter and many times being poor I couldn't afford to drive that far to get a oil filter. So I bought what was available at the nearest place to save gas. And that drives a lot of what I do....cost... to get to where this stuff is, and how much it is. Is Fram cheap? No, it's a little more than others. So I'm not trying to save money there. If I was I'd be getting some Chinese knock off for a buck. I don't want to do that. And filters like Royal Purple, is probably the most expensive or some other high end kinds. But I don't really know where to go to get these high end filters, probably because I haven't bothered to look for them. It all boils down to cost, and here I'm endangering my engine due to laziness and don't want to spend the money to keep from grenading my motor? I don't know. I've been using Fram for decades and nothing bad has ever happened so that's the one I use.
