Well I bought another car a 96 Honda Civic EX Manual with 200k on the clock. Everything stock just overinflated tires. I travel 30 miles each way to work with A/C OFF I have been getting over 40MPG at 60-63MPH about 5% of the drive is city so for the whole trip I get over 40MPG. I want to see the best I can get with A/C OFF then see what I can get with A/C ON. I think it makes a big difference on these small 1.6L motors maybe 5MPG if I had to guesstimate now. Right now I have stock rims and tires on it as soon as I get my highest MPG for the trip to or from home I am going to put my larger rims and tires on to see if it affects the MPG negatively.
