I'm close to the same mpg's as BR. It's at approx. 17 right now. I'm only right at 200 miles on the odo, so if it gets better as time goes that will be a plus. If not, I'm happy with it where it is now. I really didn't expect that much.Interesting, I'm getting pretty consistent 16.5mpg with 90/10 city/highway on stock KO2's. I've been unable to get below 14.5mpg in pure city driving, dropping the hammer pretty hard. Had to work to go that low. But that was with the auto, so that's probably making the difference.
Could not agree more regarding fuel quality’s influence. Good point.Have a '19 JLR with the 2.0 turbo, totally stock with K02s at 38 psi. Worst tank so far was 17.6. Averaging 20.2 now. It's going up slightly every fill up. Probably due to the summer blends of gas. Totally flat, no elevation changes. Probably 75% city and 25% highway. A lot of bumper to bumper traffic. I think quality of fuel has as much to do with MPG as driving style. How much ethanol, winter blends, summer blends, etc can have a effect on milage.
It works fine unless you have the acc on and no engine running, I think it counts the time ignition is on.Some say that hand calculation is more accurate than the onboard computer.
I’m sure they’re right, IF they get the tank exactly as full the second time as it was the first. Not so much if not.
The JL tank is finicky about taking fuel onboard.
If you’re going to random pumps at random stations with random driveway angles, and trusting clickoff, I wonder if you’re getting results as accurate as you think.
The computer may not be perfectly accurate, but I am inclined to think it’s consistent.
