First Autozoner today:
"You shouldn't use Motorcraft plugs. Your engine wasn't designed for Motorcraft plugs"
"It's a Ford Duratec. It originally came with Motorcraft plugs."
"You put a Duratec in a Mazda?"
Unfortunately, I was driving the Turbo Clown Hearse so I couldn't go pop the hood and show him all the Ford ovals. Also, they only had 4 plugs in stock.
Second Autozoner today forced the upsell the antiseize and di-electric grease. He also gave me a funny look when I asked for Motorcrafts for a Mazda but didn't hesitate in getting them for me. But he was relentless on the upsell.
"You should really get the antiseize."
"No thanks. I have plenty. A little goes a long way."
"But you should really use it on a Japanese car with and aluminum head. Let me get you some."
"No thanks. That's not necessary."
After pulling out the NGK G-Power platinums, I do have a bit of buyer's remorse. They were better than I expected. But that's a different story.
