Just did an oil change last weekend on the wife's Corolla with the sludge-prone 1.8 engine. I've been using Castrol GTX and Purolator filters since I started doing the changes, but I wanted to try something different for giggles.
Among a few other brands I bought from Amazon, I picked up a Taiwanese-made FULL filter. It looked like a basic black OEM-ish replacement filter with what looked like a coil-spring relief valve built into the dome end, a thick round O-ring, and shrink-wrap to keep the guts rust-free. Only thing I really didn't like was some excess glue that was squeezed out of the endcaps on the bottom near the relief valve, but I rolled the dice and used it anyway.
During the change after a 3k OCI, I noticed the same Castrol I had been using with the Purolators seemed noticably cleaner with the FULL. Granted, 3k is not a lot of miles, but the oil always seemed ready for a change when I did it at 3k so I've been sticking with it. This time around, the oil didn't seem very dirty or contaminated at all. An analysis would obviously tell the real story but but the looks of it, the FULL was doing a fine job. Even the excess glue was still in place, thankfully.
Sorry, no cut-open pics! The filter's long gone. No part number either but it would be whatever the L14476 crosses over to.
I've got a cheapo Valucraft on there now and I'm anticipating it'll do a fine job since it's just a good standard-grade Champ filter (like the AC Delco and STP I also picked up). I'll probably try a Baldwin next, or a Wix, maybe a Mann, possibly a Hastings...
