Hey Guys, first post for me - just recently bought a 2006 Accord Euro CL9 with 97,000km on the clock. bought from a dealer with new tyres.
so far so good for fuel economy - better than i expected.
1. First Full fillup was Caltex Vortex 95 and got 640km when the reserve light comes on - then filled up, average 7.2lt/100km 70% Freeway 30% Urban
2. filled BP ultimate - improved economy again down to 6.8lt/100km so far with 540km and gauge is saying there is a little more than 1/3 of a tank left. so far so good! again same ratio freeway/urban.

on 1 run Monash Freeway and Eastlink - about 30km distance i managed to have it down to 5.2lt/100km on that stretch which is amazing!
