What did you do with your Thunderbird Today?

Tire pressure is important. Mydrive is 90% highway at 60-65mph. Do you have ability to check fuel trims? I use forscan to monitor mine.

He's OBD-I so no fuel trim data.
I used to get just above 30 in my old '92 V6 on the highway when it was in proper tune.

When I was driving 120 miles/day, I could tell tire pressure, oil age, trans fluid age, and suspension wear just from how the car drove.
I could tell gas mileage pretty well too.
I change oil every 2500 mi, trans fluid every 25k, and air filter every oil change. I got 21-25mpg, although by a random thing of following a state trooper into maryville for a week, I found out the non-hooning mpg was 35mpg@80-85mph. Difference was everyone got out of the way ,lol.

So you're saying the Nascar drafting to conserve fuel was a hoax? The CD is what drew me to the bird in the first place. Slick as glass when everything is right. My rear shocks are dead and so I may be a little lower than stock.

Nah, I was just using the gas station reciepts. So, I used about an 1/4 of a tank and gone 60+ miles. That is better than I have seen in years.
