My turn for my first post. I drive a 1985 Fiero, which has a 2.8 V6 and a 4-speed manual transmission. I do some flat in-town driving, which amounts to about 2 miles (each way) per trip. I don't drive in town much, though, because I prefer to ride my bike--2 miles just isn't very far, and the lack of hills also helps. I do more driving on the highways. The transmission seems to be well-suited for 55-60 mph, so that is what I do. I run 5W30 oil, 87/89 octane gas, and use the cruise control quite often (although sometimes it doesn't feel like working). Just a few days ago, I put a bit more air in the tires--45 psi. I'm curious to see what kind of difference that makes. Besides keeping the headlights down, does anyone have any suggestions?
