K&N Fuel Economy
K&N Fuel Economy
As I mentioned in another thread I drove to Somerset last weekend and got some surprising fuel economy. I wasn't in any way driving with a light right foot (especially on the way there as I was running late and the country lanes were awesome) but the round trip was 330 miles and I only used two thirds of the tank.
Based on that, if it had been a slightly longer journey I should have been able to get 500 miles to the tank, which would roughly be about 35mpg? To add to it it was really hot and the A/C was working pretty hard so I can't really understand where that economy came from........could it be the K&N?
Don't do a lot of mileage so will be a while before I can work down another tank, but will have to see how much I get during town driving (but I'd imagine that would be less of a difference)
DJ Wozza Sorry mate but I really doubt that. I think you will find the last (lower) third on the gauge always drops very quickly
compared to the top two thirds (or at least it does on mine :o)

Roadside Tech You say you don't normally do a lot of miles? maybe it's telling you to use it, and out of town

Would be interesting to refill the tank and see how much is needed to fill it, then to calculate the mpg based on how many miles since filling ?
I reckon my K&N filter probably improved by fuel economy by somewhere between 5 and 10%, very roughly ?

Roadside Tech OK, OK, no need to show off, that's a dream to some of us

Marsdendean Does your K&N make the IS sound a lot better - any chance you can post a video for us. Im thinking of getting a K&N and chopping the second part of the airbox off to create a little bit more noise (thanks Bandit for the tip!)

Marsdendean 145 from £20. I get around 250 from £60, just shows what the auto does fuel wise!
