I know I keep posting about brakes so please forgive me but I'm stumped... I was getting 22mpg my brakes stank, were exceptionally hot and were replaced with genuine Honda. So calipers, pipes, fluid discs and pads all new. I now get 25mpg and the rear discs get just as hot as the fronts. I compared with a friends FR-V and she's getting 29mpg around Milton Keynes and her rear discs were cold after a 10 mile drive. Can someone with a. 1.8 auto go for a 5 mile town drive and tell me if their rear discs are hot to the back of a finger. I went back to Honda who said they had it on a machine and there's nothing wrong. I'm going to clean the plugs and double check the tyre pressure to squeeze as much MPG as possible. If all is normal I can't believe Milton Keynes roundabouts and my driving is using so much fuel. How much is an lpg conversion? Maybe I should consider one of 25mpg is expected.
