no idea what the symbols are you're referring to, but if you want an oil filter, go down to autozone or advance and pick up a purolator pl14610. slightly longer than stock, MUCH better filter media performance, and just flat out MORE media. also a quality anti-drainback valve.
i like them better when they were blue, but now they are gold-ish and have an abrasive material on the outside of the filter to more easily grip 'em. i'm very nervous about that grit getting in the filter, so i've been giving new ones a quick spray of air to blow anything loose out.
you want the pure one - only those are gold (vs blue box). the older blue can variants came in a silver box.
