I change the filter from the stock filter. I have had K&N filters in previous vehicles. I installed it and did a routine trip to the cottage. Coming home, I could notice a difference in the fuel cage. I should have had the fuel light come on when I got home but it was not. I drove short city trips all week and light finally came on Thursday. I did not do the actual milleage but I can tell you that the light should have come on Monday at the latest. Dave
