I just got my rx350 f sport refueled today when I only have 16km of range left. I noticed my car took only 60 litre to get a full tank. I read the spec online it was suppose to be 19.2 gallons so roughly 72 litres. Can any tell me if they have the same problem? Thanks!

Welcome to the forum!

This situation is normal and has been for years on the RX. Lexus reserves a (large) margin of fuel in the tank even when the guage shows Empty. The subject has been discussed many times, and those threads can be found with a quick keyword search. Here's one to get you started.

Enjoy that F-Sport!

Thanks for your information! Now im not concern anymore. So I should still fill up the tank when ever the light turns on right? So It will be better for the car?

^^^ Welcome to the forum! It is best practice to minimize the time your tank is close to empty in winter driving. In short, when the light goes on, you have about 10-12 L left of fuel. I fill up by then across the seasons.

Yes, fill it up when the light comes on or just under quarter tank. It will give you peace of mind, that's good for you will be good for the car. It's all connected.

I don't like to run mine below a 1/4 of a tank. Continuously running your tank low till the light comes on is not good for the in-tank fuel pump. The fuel pump relies on the fuel in the tank to keep the electric motor cool. We all know how expensive a fuel pump replacement is.

Oh I will try to avoid that. It's very good to know this! I always wait till there's 0 range left.

I never had an issue with running down to the empty light in any Toyotas I owned, both newer and older.
However, I have heard certain German brands being notorious when it comes to running below 1/4 tank.
