Today I went to the wal mart tire center to see if they could patch my tire since I picked up a small nail. I trust them with that low level work because its easy.

anyways

As the girl was filling out the car info( because she couldn't scan a barcode for a VIN on my old tank) I started it so I could park it before they would work on it( 90 minute wait... pfft). She was up front and commented, "Your engine is knocking really bad, how long has it been doing it?"

me: "well, ever since I started putting diesel in the tank it started knocking and making tons of black smoke at WOT"

her: " you shouldn't put diesel in it"

me: - laughing my ass off as I drive away and decide to take it to the goodyear tire center across the street.
