Came across this site last week in my search to improve MPG's... I commute on mainly 80km/h or 50mph highways... I drive at least 120km's per day round trip excluding any errands in the city...

I previously owned a 1997 Saturn SL1 base model 5spd with 343K on that I felt under normal driving circumstances I was doing fairly good with sticking to 90km/h or 55mph and even in the winter months getting 45-47mpg imperial mpg... I only started to track to mileage in January because I started this new job 60 km's away from home so now it seems to matter so I can put more of my paycheck into my pocket..

Circumstances changed, I wanted to try something new but still not have a car payment, I decided to buy a 98 Honda Civic CX hatch, more fun to drive, but no tachometer on it! I know that at 90km/h my Saturn turned out 1900rpm which I feel is pretty low for a 4 cylinder... Anyways, I am hoping to get high 40 mpg imperial or possibly better if possible on the new DD.... I am starting to have some regrets about letting the Saturn go, I think it would have been easier to break 50mpg in the Saturn than it is going to be in my civic... Well sorry for the long hello, I hope to learn lots along the way...
Welcome!

The 1998 CX will have something like a 3.725 final drive and a 0.702 5th gear, so it'll be turning a bit faster than 1900 rpms at 55 mph but nothing really major. Get an Ultra Gauge or ScanGauge and learn to "drive with load". The gauge will pay for itself within a few tanks. Pump up the tires. If you have power steering, take the belt off. You can easily put it back on, but you really don't need it on this lightweight car and deleting it will help you reach your goals more easily.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
