Hello all-

I am getting around 23.5MPG on the freeway going around 85mph in my 86SDL. Is that about correct? The car seems to run well and only puffs a little black smoke when you hit the throttle from a low speed or under hard acceleration on the freeway. 0-60 takes a bit under 12 sec but I was at 3500 feet of altitude when I did the test.

I am not an "economy" driver and tend to cruise at high speeds. I just read about people getting way more economy and wonder if there is a problem.
