This is fuelly results for Mazda 6 http://www.fuelly.com/car/mazda/6/2013

All cars these days claim to have the technology to improve FC. Even if u drive Axia and is heavy footed or stuck in jam, ur FC will skyrocket. Same applies to a Mazda 6 or a Honda Accord or a Camry. I'm now using an accord 2.0 which gives me about 11-12km/l on 60% city drive 40% penang bridge drive. During days i am more heavy footed, it drops to 8km/l. Therefore, drive management is important in order for u to get good FC.

For ur car, i think u pay ur loan every month. so the most important thing is that when u go to the bank on a monthly basis, u will feel that what u are paying for is worth every single penny becus u like the car!

Just my 2 cents as well
