Right now i'm getting 19.7 in my 2010 - also mixed driving, some highway, some local.
Can you please post the link or provide the specs for the right K&N drop filter f0r my 2010 FX35? (Same as yours)

Re: 8.5 mpg local and 10.8 mpg at 75 mph?

Recently drove 2000+ miles from Washington to Illinois. Was doing mostly 70-75 mpg on the highway and the display showed 21.2 by the time I reached my destination. Every time I filled up, the computer estimated 400+ miles to empty, usually around 420-440 MTE. This was with my rear seats folded down and packed with personal things, around 300 lbs worth.

City driving fluctuate a lot for me, though. Heavy foot is mostly to blame. Anywhere from 10-17 mpg. I accelerate out of stops way too often.

I bought my FX used at 2009 with 17500 miles. One of the first few things I noticed was that it was getting low gas mileage and the RPM needle was erratic or spiked way too quickly without giving me power in return, even with a light tap of the gas. I did the proper ECU reset, which is like 10 step process by depressing/releasing the gas and turning the ignition on and off at specific intervals, after I did the mods in my sig. Fixed my RPM spiking issue and my gas mileage has been consistent since.

I use mobile 1 5-30w and mobile 1 filter. I also keep my tired inflated to 35 psi min. I always use cruise control if I'm on the highway.

On a side note, driving through North Dakota on the I-94 in Feb suck monkey balls!

I would clean or replace the MAF sensor before doing anything else. In fact, with 196k miles on the clock, I'm thinking about replacing my FX45's MAF sensor soon. Not the whole canister, just the sensor. Much easier.
