I've never seen a factory auto ka24de do less than 25mpg combined and I am pretty sure its 28 to 29mpg highway if the car is cruising maybe 65mph instead of 80mph. I never kept the ka very long though. The sr20 I have measured mpg far more often than the KA and I know for sure 30mpg is just a standard for the 5-speed swap. The lowest I ever recorded for sr20 was 25mpg combined and this was with an engine that had over 250,000 miles and 120psi of compression across the board.
Everytime I fill the tank to the top and record the mileage, add it to a spreadsheet, average, deviation, t-test, normal distribution. Check speedo accuracy.
My quoted numbers are scientific and accurate.
