Wow, I just did 300 km with 90% highway and only got 19 mpg! I have 5 people in the car and some luggage but no roof rack or anything else. Will be doing another 500 km soon so will see whether things change.

 

Recent trip from Pittsburgh to Buffalo - just over 19 with 2 adults and 2 kids. Avg speed 70 or so. Would love 22-24 but I don't see that happening.

 

With a light foot and a lot of patience on the highway, you can easily break 20. But if you want to keep up with traffic, more like high teens. Around town, solidly in the mid-teens.

So, i took another road trip from NJ - Toronto (Mississauga ) - NJ. about 478 miles each way. made it to Mississauga in 1 tank. Cruise set at 60 MPH , traffic co operated really well. no lines at the US- Canada Border. At the hilly area past Binghamton,NY the MPG dropped to 24- 24.5 but it recovered once i entered PA.

Could not be happier !!!!!

 

I have just under 900 km of driving ahead of me... I don't see mine getting any better now since I have installed the cross rails on the roof.

60mph is quite a test of patience too I usually set my cruise control at between 120-130 km/h depending on the speed limit.

 

haha Agree! 60 MPH is a test of patience. good thing is i can tolerate cars passing me.

 

So just completed a round trip from Toronto, ON to Washington DC. 1,725 km (1,072 miles) round trip and averaged only 12.8L/100km (18.3 MPG). I'd say about 5% of that was city bumper to bumper traffic and the other 95% were mostly highway. Mind you, highway isn't same as Interstate highway for a lot of those miles and there were a lot of elevation changes. Half of those miles was with the roof cross rails installed. There were five people and lots of luggage in the car.

 

If you drive 60, cars are not passing you...they are shooting past you. I drive 70-72 and I am usually the slowest car on the road. People just can't relax anymore.

 

I get that too in the morning... I can be in the slow lane at 70-75 and have cars in lanes to the left doing 85-90 in places.

 

Hello I just got my gx460 2012 , (very happy after lx470) , what tire pressure do you recommend to put ? Feels like the mpg is too low 10mpg

 

32-35 seems to be the norm.
10mpg is way too low....

 

The recommended tire pressures are located just inside the drivers door...on the B pillar. If it's 33 psi, moving to 34 or 35 will give you a more firm ride and might improve your mileage. It won't be much, but you might see an additional 0.5 to 1.0 mpg

Just make sure that you have a good tire pressure tool, the TPMS on the Lexus is pretty good, at least on the four I have owned. Make sure you are at least what the recommended pressure is...

 

Thanks a lot for your help I'll let you know the result 👍

 

Check the pressure when the tire is cold. As the tire warms up, the pressure will usually increase ever so slightly.

 

I run 32-33 COLD and it gets to about 35-36 psi by the end of the day. 10 mpg is very low.
