Umm, I can't speak for a 02 box, but on the inside of the gas lid on my 03 box S it s

says to put in 93 octane. In the manual, it says you can get away with 90 oct but no lower. I guess the knock sensor auto adjusts for lower octane gas, but I wouldn't recammend using anything but premium gas. The manual says only use 90 in a pinch, and thats 90 not 87, so I would say 87 is mucho bad. However, your talking about a 2.7 liter engine and I have a 3.2, so perhaps my rules don't apply to the 2002 box.
