Fuel Economy

Hi All

I feel like my car isnt doing great fuel and the dealer insists there isnt anything wrong. Appreciate if you can share your feedback.

I do City Driving so i expect a bit less economy. Overall on a full tank of 98 Octane driven on Eco mode gets me a maximum of 380kms before i hit the fuel light warning. I assume there is a bit left in the tank after this but all things equal, what kind of fuel economy is everyone else getting before the tank light comes on?

In terms of liters per 100km that is 16.6l/100km or 6km/liter

I have a RC350 F-Sport Automatic with no mods

Thanks for the feedback!

I think the last time I noticed I was averaging 14litres/100k But to be honest I don't really care about the fuel economy,
I drive my RC350 in Sports + mode quite often because I love the sound of the beast inside, the last thing on my mind is how much fuel I'm using.

I get 19-20 mpg driving regularly on ECO and Normal Drive. I installed a Takeda intake and it is the same but leaning more towards 20mpg.
