My K&N filter thoughts...

I am not too sure. I am losing mileage with the same driving habits as compaired to my stock paper filter.

Here is the weird thing.

When I drive harder, my mileage goes up.

I installed the filter when I was at half-a-tank...I usually wait to do a mod on a fresh tank, but I wanted to throw it in there. I am using the AVG mileage reading from the first half of the tank on the stock filter, and from now on with the K&N. Don't know if that matters or not.

I love the small [if noticable] difference in power, but watching my mileage drop slowly while driving on CRUISE is causing me to become confused. Who said 45mpg? I called BS on that then and I still will.

Anyway, I'll be needing gas come the beginning of the week and we'll see what happens. I plan on running the 93 tune again at the next fill-up, and then switching back to 87.

Maybe I need to smoke the computer and reset the battery after installing the filter -- I always did on my other vehicles when I did the K&N FIPK. Hmm...

Anyway, when I drive harder, I gain mileage. Odd.

hard to say, I have never had that problem on any other car and I don't have one yet for my Fusion,
seems rather odd to me as well. yeah, I really don't see this car getting 45MPG even me with the 2.3
the new Toyota Yaris, boasts 40mpg but hello it has a 1.5L 106Hp engine, and even my '84 Chevette
got almost 35Mpg, when I wasn't driving the hell out of it, but too it had a 1.6 in it, smaller engines,
better mileage, but you sacrifice much power for the mileage abilities.
