First:

THANKS TO YOU ALL!

somebody left a snyde reply on another post "thanks for keeping it short.." lol and I thought that everyone else might agree.
The reason for such a long post is ...well mileage is a war of attrition. The details count.

I've been wondering just why plat plugs are worth a crap and I honestly don't know.
I'll try to replace them with my oil this week. I've got finals two weekends from now, so I might wait a little while.
I'm thinking the Bosch copper are fine? When I bought these plugs, I went to Autozone and they recommended the +4 because they're like 8$ apiece, but they were really no help. I bought the plain platinums because I didn't really know what to buy.

What are the proper plugs?

Also my turbo is really light on oil consumption, it just seems weird that it's dripping outside the turbo. I tried hard to keep my foot off it (I was pretty good, only two boosts in 150 miles). I don't have mileage figures yet.

The EGR sounds plausible, I think it might be part of the problem and I will replace it this summer when I can afford it. I have to buy health insurance this week. bleeuuugh.

I'll post back,
-Will
