Hi guys,
I have been reading about MPG issues etc and yesterday got my car's first service done. The dealer (Lexus Guildford) remapped the ECU and will order the fifth injector if the mpg do not increase....I got the GS450H for the day and that car is out of this world.....you really do feel like you are the king of the road in that car. Its really fast and really heavy on fuel....20MPG to 22MPG was the best it could do but then again you cant help flying that car.......you must try it if you get a chance.
My 06, IS220D SEL seems to have become louder since its gaining mileage (now 10K), don't really know if that is normal or not? Since new it’s been doing max 37MPG so if I do a tank full with around 56Liters I would get Max 520miles to 540miles (if I was really gentle with it). I think I have never got more than 540miles out of my motor..... But on average it would tend to run out of fuel when it’s done 480 to 500 miles.......how about you guys??
