Hey guys, just bought a '98 civic lx 4cyl with 150k miles. It leaks oil at the valve cover and oil pan but I wasn't too worried, it only cost me $1k. Everything was going smoothly until I decided to drive it from Utah to Idaho. I drove and average speed of about 80 MPH and was disappointed to find I only got 27.7 mpg! I was really expecting to get about 45 mpg. Why could this be? I've also noticed the car doesn't seem to roll easily in neutral like other cars do.

it's an old ciic, that's the mileage they get. Modern ones are completely different desig
