The reasons I usually use a longer stretch are a. there is one just south of town here on the interstate and b. when you drive an 87 Comanche with over 180k on the clock at 6500' elevation and a 5-spd gearbox in front of 307's speed control is a tad hit or miss.<G>. Turns out, my result with 235/75R15's was exactly 7% slow - enough to get you a ticket in most states where the speed limit is 75. Besides, I was already bored with the trip and still hadn't reached to Colorado border when the destination was South Texas. As an aside, the highest mileage I ever got for long trips in that Comanche was 27 mpg. Colorado Springs -> Abilene, TX using 5th gear (2250 RPM) and a 40 kt tail wind all the way. Believe it or not, the second highest was 25.5 mpg CS to Billing, MT into a 35 kt wind running 4th gear and 2700 RPM all the way - go figure. -- Will Honea -- Posted via a free Usenet account from http://www.teranews.com |
