I don't like those who tell me something I own doesn't exist. I've had this twice with auto parts stores. I got told my Spitfire only used a male oil filter. I'd have to force the issue to get a female one.
Last one told me that Toyota never made a 2.7 liter 4cyl. Tacoma.
I really don't care if people think I'm a little green alien as long as I get a polite response. I'd rather people know less.
