How about circling the sticker that says minimim 93 octane with a red sharpie? That would seem more effective than just a piece of red tape which doesn't really indicate anything.

It doesn't have to, just needs to be a visual cue to stop and think about what I am doing. The gas cap on our diesel is green which works as a great cue for it since most diesel handles are green. The locations that have 93 or even 100 around here will typically use a red handle so the color has significance, even if you are just selecting 91 on a black handled pump.

My absent mindedness seems to run in pairs. 1000 miles in two days and I frickin do it again 60 miles from home.
No cheesy additives this time. When she started coughing and didn't want to restart I shut her down and called AAA. This will be the last time this happens I guarantee it. She deserves better. But the least I can do is a proper ride home and another full draining of the tank.
Now who was it that said 87 wouldn't make these run bad?

I'd bet this(the poor performance with regular fuel) has to do with the fact that your car has a tune which doesn't allow the DME to retard the timing enough to compensate for the 87 Oct. fuel. I can't believe a stock 996 would perform this poorly with 87...although I can't say for sure because surprisingly in 10+ years of 996 ownership I have never mistakenly used 87 Oct., at least that I am aware of anyway.

Admit it - you did this a second time on purpose just to prove some here wrong...

I'm up to 40 gallons. One more time and I'll have your drum. Of course $.05 of red electrical tape has permanently solved the problem so there is no chance of a threepeat. None.

Good idea. Finally got back from vacation tonight and finished draining the bad juice and getting in the good stuff. After the knock sensors adjusted she is running like a top again. Tried using the Durametric to activate the fuel pump but it wouldn't stay activated. Went back to jumpering the relay and it worked like a champ.
