I have a typical 2000 Kia Sephia; 4 Cyl, Auto Transmission; 40,000 miles. I have been extremely disappointed with the fuel economy ever since I purchased the vehicle, new.. Highway driving at 60 to 70, around 24 mpg. This is maybe 1 mpg more than I get with my 95 V6 Honda Accord. Of course, Kia will offer no relief for this.
I live in Florida, so the AC is on constantly, and am wondering if this can really suck down the mileage. I've been wondering if anyone else is having the same problem. From what I've read, my situation seems atypical. Are there any checks (other than making sure the air cleaner and spark plugs are replaced) or injector mods that could improve this mileage.
Thanks, Tom from Pensacola, Florida
