Fuel Economy...WTF?

For what it's worth, I never trust the trip computers so I always to the math on my vehicles (just a habit).
My first two fill-ups the computer was dead on to the tenth.
22.5, and 23.3.

I've found that how I drive around town profoundly affects the mileage.
(I know, not a revelation)
Lord it's hard to stay off that pedal at lights!!!

I just started gathering data. Here is what I have so far...

Hey Spear... From what I've found with my '09 FX35 and this, the VQ motors don't start getting their best mileage until they are fully warmed up. When I just have my 15 minute trip to work, your mileage is close to what I'm getting. Once both of them are warmed all the way, the mileage goes way up. Just an observation for what it's worth.

Yeah, the car runs great so I'm with you guys on thinking it's engine temp related.

First it was oil coolers, now it's going to be engine block heaters...LOL

i have tested the trip computer multiple times it is pretty darn acurate, infact its acurate enough i dont have to test it the old fashion way any more.
