Hi, I've just got a new LC300. According to the specs, it has 80L main tank and 30L sub-tank. Today I filled up the tank when it shows only 80km range left. I expected to add just over 100L because there should be less than 10L left in the tank. But the tank was full after I added 86L. Does anybody know why? Was this just due to inaccuracy of the fuel gauge, or have I missed anything?
