rx300mm

With everyone being aware of gas prices, I was looking through RX330 brochure on the web and I can't understand the gas (in gallons) consumption is different in USA and Canada.
Here are the details from the two websites (Lexus.com & Lexus.ca)

USA
Fuel-tank capacity: 72 L
Fuel consumption: 18/24 mpg city/highway (AWD) ]

Canada
Fuel Capacity litres 72.5L
Fuel Consumption - 22/31 mpg City/Highway (AWD)

I wonder is the "gallon" size is different in two countries ?

Could it be because the milage is in kilometers??

Canada uses imperial gallons. An Imperial gallon is 1.2 U. S. Gallons. so if you get 20 MPG in the U. S, you will get 24 MP(i)G in Canada. The testing regimen may also be different. The EPA has a specific testing procedure that results in the MPG numbers on the sticker. Canada is not subject to the U. S. EPA, so I imagine the difference in the numbers could also be due to differences in testing procedures.

As far as the different fuel capacities, that's a puzzler. but I am looking at a 0.5 liter bottle on my desk, and it's a small enough difference that it's probably just rounding error.

Who knows. I've pumped more gas than the specifications say in many of my cars... without topping off.

mmahamm, you are right, I just looked it up on answers.com and here's what it came up with:

1. A unit of volume in the U.S. Customary System, used in liquid measure, equal to 4 quarts (3.785 liters).
2. A unit of volume in the British Imperial System, used in liquid and dry measure, equal to 4 quarts (4.546 liters).

That explains tons about the "gas consumption" talked about on other threads
