I was joking about your quarter-mile ET. I just figured you were treating traffic signals like "Christmas trees" at the track and getting your foot into the throttle at each stop light.

Thanks! I was at a loss as to what to check next. I was thinking the PCV and hose, but I've yet to have one plugged up by 50K, though there is a first time for everything. One clue is that with all variables being equal, i.e, outside temperature, etc., the car seems to take an extra two or three minutes to reach normal operating temperature. I can recognize a t-stat that's stuck open, as 1987-92 Acuras were famous for that problem. I assume that a really thick 30 wt. can cause this?
Also, if it is the mass airflow sensor, why do I not get a "check engine light?" And last, but not least, what about the throttle body? Is it possible it needs cleaning and could be part of the problem? I use 20 ounces of Chevron Techron every six months and I always use 93 octane BP, Mobil or Shell gasolines.

I was thinking the same thing. I'm going to change the oil in early June and do a UOA on the Saab 0W30 synthetic turbo oil that's been in there for the last two changes. I was thinking of going back to Mobil 1, but using the GF-4/SM 10W30 instead of the "old" or "new" 5W30. Any thoughts, guys?

No, I don't blame the Turanzas. I had read numerous reviews on TireRack.com that cited a drop in mileage with those tires, but the claimed mpg loss seemed insignificant (1 - 1.5 mpg). I like the Turanzas. They handle well and are quiet and are much better than the Goodyear RSAs that were OEM.
