Why is my cars gas mileage so low?
posted by LoopyG to travel & transportation (35 answers total)
2 months ago I bought a '97 Honda Civic EX with 150K miles on it. Since that time I have performed some repiars including: New wheels and tires, replace all the belts, replace water pump, replace engine seals near the belts.
I have been watching my fuel usage, and have been seeing a measly 26mpg highway and 22mpg city. The manufacturer claims the car should get 38mpg highway and 32mpg city.
There are two factors I know probably reduce the mileage. One is the current tires are lower profile than the stock tires, and so probably knock about 2mpg off the mileage. Also, the car is old and has a lot of miles off it, so that should knock off a few mpg also. But other Civics the same age and miles driven get much better mileage than my car, so there must be something else.
The two ideas I have currently are get an oil change (its almost due anyway) and replace the air filter. But I am curious to other suggestions you MeFites have that could improve the mileage.
As for things like driving slower and combining trips, such suggestions are good tips but I already follow all such suggestions to the T. I drive an average of 150 miles per week (not including drives for vacations), and rarely go above 70mph. I also coast as much as possible, accelerate slowly, and use the brakes only when there isn't room to coast.
In any case, after this long post, I am eager to hear what suggestions you guys have for changes to make to the car or engine to improve the mileage. I am willing to spend as much as a couple hundred dollars to improve the mileage, as I estimate the lower mileage is costing me around $36/month in wasted gas.
