Hi Blue,
The same filter peaked my interest. It appears to me that the PL25230 may be discontinued. I have however been able to find the Classic L25230, and the Fram orange PH8316 or Tough Guard TG8316 which are for the same applications and they also have the double anti-drainback feature.
All of them seem to be priced higher than other Classics/Frams but I haven't been to Walmart yet to see if they are higher there.
