and thanks for the info on the plugs. how much do they run at o'reallys?

it may very well be fuel additives: Refineries make a Summer and a Winter blend. It could just be what's in the winter blend causing the discoloration. I don't think the summer blend has gone into widespread distribution yet.....and probably won't hit the northern states till mid-April/early May.

Coolant when burnt will leave whitish residue/deposits. The red is from the MMT or possibly another additive in the fuel. As a side note, if you're ever trying to diagnose a fueling issue such as an injector, you can put in a bottle of the cheap octane boost with MMT and drop in a new set of cheap plugs. Then drive the car for a few WOT pulls and pull the plugs. If one has a lighter red tint you'll know that cylinder is running leaner. It's not as good as per cylinder EGT probes but can be handy for quick troubleshooting.

I've never noticed any difference when I use other gas. I'm about to have to fill up soon, maybe I'll try out Shell.

I just discovered that the Shell nearly 4 miles from my house has 93 octane. Looks like I found a new place to fill up!

Just wish I knew that a long time ago.

i have been using shell 91 lately, changed fuel filter, changed intercooler pump, and changed out plugs to ngk step 1 coolers. i gapped the plugs at .040 and now i only hit 15psi. should i play with the gap till i find the best set-up or can anyone tell me anything that could help me. car runs great now and no red plugs again (yet *praying for the best*).
