Gas mileage questions
On my Range Rover Classic the gas mileage drops slowly. Once it gets to 2mpg lower than normal you can change out the O2 sensors and get the mileage back.
Is it the same with the 4.6 Discovery as well?
My mileage has dropped nearly an entire 1mpg from when I first got her with no changes to the engine or rig at all.
What's the average life expectancy of the O2 sensor on a Disco 2?
