I've got it on mine right now, bottle's empty right now tho.

: anyway, unless you've got tons of miles on your motor you'll be fine with the 55 shot. I've been running it for several months now, and the motor doesn't even seem to care. I don't use it as much as some do, actually compared to most I probably hardly use it. I usually fill the bottle every couple weeks or so (partly cause the place to get it filled is two hours away)
Mine's a 99 auto f23a1, so we're talking about the same stuff. I had about 63,000 on the motor when I got it, I have about 68000 now. Not sure how many bottles I've been through. Just don't be stupid with it. I also put some different plugs in when I put the kit in. Started off with the Zex plugs, now I've just got some Bosch +4 ones. Have fun, good luck, and don't screw up with it
