Your sudden reply in blue surprised me.That is where you are wrong. Getting 6km/l on his STD and getting 6km/l on a 4G63T is totally different. He sat in my car before and mention why your car so much torque one....lol
Hmm, you are right about 6km per litre in Sylphy VS 4G63T. 4G63T almost triples the output of Sylphy.
