In my 2006 GS430, I just completed a 400 mile trip each way this past weekend and achieved 26.1MPG one way doing 70-85MPH and some traffic driving then 27.2MPG the other way doing the same speed. During normal work weeks with traffic 50%, it gets 21 to 24MPG.

Im not sure if something is wrong, or if its the way Im driving, but my gas mileage sucks!
Mixed driving highway 40% and city 60%.
My computer says Im getting 11.1 L/100km = 21.19 mpg, but it lies.
When I crunch the numbers (70 liters = 554 km) = 12.64 L/100km = 18.61mpg
100% stock, 300 AWD, 100,000 km (62,000mi), proper psi in tires, 91 octane gas, synthetic blend oil every 5000km, clean air filter and just had injector flush done and new plugs put in.
It seems like after I did the flush and new plugs my mpg went slighty down also!?
Any suggestion of what I can do? is there something im missing here.
Tried the PWR mode after reading a thread that it helped mpg but made mine way worse, briefly tried SNOW mode but find it too annoying to have to push the button everytime I start the car. Between the insurance and gas money I put into this thing, Im starting to seriously debate if I can afford it anymore.
$90 ($1.26ish/L) of gas to get 550 km sounds ridiculous to me.

my gas mileage
2009 gs 350
I just got my gs and filled it up with shell plus. Drove about 4 hours all highway cruise control at 80mph and the odometer said i was averaging 22.4mpg. I filled it up after the drive and divided the miles I drove by the gallons I put in and got 22.9 mpg. Kinda disappointed bc I just came from a g35 coupe (which is considered to get bad gas mileage) that got around 18 mpg local and 20 highway. I was expecting mid 20's highway in the gs 350 because I read reviews of the gs 350 getting good gas mileage.

Do u think that is most likely? I got the car from prestige lexus. Supposedly they only sell cars in top shape and do the 161 ppoint inspection. It has 42k miles and clean car fax. Im hoping the car has the potential to do better on gas.
If the car is under warranty I would take it in and complain of poor gas mileage.
