Welp, I got the opportunity to drive a 420 mile loop today. had to deliver a buddy to Ft. Lauderdale airport.
Thought it would be a good chance to get a base line for gas mileage on the "new to me" '89 Buick Boxie, AKA the Way Cool Wagon.(Old's 307 Y motor/THM 200 4R)
Rolled out of Venice at 5:30 AM held 78 MPH (very light traffic) all the way to the Airport. A/C off, Averaged 16.5 MPG. (~62 deg. clear/dry.)
The speed limit on that stretch of I-75 is 70 MPH. It's known as Aligator alley and anything under 80 is pretty well tolerated by the FHP, with reasonable lane discipline. (in the wee hours, it's not unusual to be passed by South Beach screamers at 160+MPH)
On the return trip, I held a steady 65 MPH. A/C off, Averaged 18.8 MPG. (73 deg., clear, calm)
The WCW is averaging ~ 13.5 to 14.0 MPG with mostly careful in town driving.
Seems a little low, for a baseline, but it's a place to start. Wadda ya'll think?
Any input as far as tuning handles, tip's and tricks would be greatly appreciated.
