So when do you fill the tank? My dealer said I should never let it go below 1/4 tank. I did that with my first tank, and got 280 miles. Sure I could've gone more miles, but I was kind of scared at how the dealer told me not to go below 1/4 tank.

I want to get input of other RXh owners on when you fill up, and why. Thanks in advace.

I fill up when convenient. Usually at 1/2 +-1/8.

I keep it simple. I refuel when I reach 400 miles. That's usually about 14-15 gallons. They say it's a 19.1 gallon tank. Should be safe...

IIRC, my manual says it's a 17.2 gallon tank. Is it 19.1 with reserves?

I believe both the HiHy and Lexus are 17.x gallons - When my HiHy gas light came on and I filled it up it took just a hair over 15 gallons. I believe the light comes on when you are down to 2 gallons.

Jeff,

Okay, looks like I've reported some incorrect information. Toyota's website reports a fuel capacity for the regular gas-version of the Highlander at 19.1 gallons. There is a very subtle bug in their website. If you go to www.toyota.com, click on Hybrids > Highlander Hybrids > Specifications, you will actually get the gas vers specs which can only realize by the small title "Highlander (Gas)".

If you then click on the "Highland Hybrid" picture in the upper right again, you get the HiHy specs... which reports a fuel capacity of 17.2 gallolns, same as the Lx400h.

Grrr. My bad. I also verified in the specification section of the my HiHy owner's manual that the tank capacity for the HiHy is 17.2 gallons...

-Han-

My HiHy owners manual states the tank capacity is 17.2 gallons - and with my experience of the idiot light coming on and doing a fillup, only a little over 15 gallons go back in..... . Although, I normally try to fill it up when it reaches 1/4 tank.
