I just got 25.4km/l KL - Seremban-KL with three stops and average speed about 90KM/H. RON95. Sorry for the dust.

Wow, you clocking 20k in such a short time, I thought I am the only few with such high mileage. The following just my personal opinion, please correct me if I am wrong.

1) I think depends on SC, they may claim that your 'dirty' (if they judge it based on mileage) filter may cause the problem to the evaporator coil, thus they may pressure you to change it on warranty grounds. So I think this part is arguable, maybe you can take the filter out before go to service and photograph it to show it to them (I scared they take a dirty filter from another car to show you during service, bad experience from the SC I used to go as found them to have tendancy to lie to customer).

2) Could be when fuel is low, fuel pressure to injector also become lower. I noticed when I open the fuel cap when tank almost empty during refueling, there is a vacumn hissing sound. The negative pressure in the fuel tank when it is almost empty could have contributed to this. Not sure whether other Insight have this experience.

3) Hahaha, at least you admit that you 'thrashed' your car . Does this happen when driving at very hot weather? Check your MID display, what is the state of charge of your battery? almost full or almost empty? Any check engine or IMA light? Not much charging could be due to battery almost full, not much assist could be battery less than quater full. Extreme high battery temperature also causes the controller to reduce the charge or assist.

4) Never heard any sound similar from bonnet in my car. But your guess could be right as there is nothing much else moving parts at the rear side of the car that could make noise after you stop and shut down engine except for the IMA battery components (fan, vent etc.).

5) Extreme hot weather and extreme driving style may cause the IMA battery and it's controller to heat up considerably. Sometimes when we parked under hot sun and the cabin air heated up, when you start driving, the IMA vent is actually taking in very hot cabin air into the battery compartment. If you do most of your driving in town with a lot of traffic lights and jam, 16km/l is actually not that bad.

Hope the info helps.

could you share with us how you thrashed the car? 

hey guys, i just install my new black color Enkei 17" rim, with 205/45/R17. Do i need to reset my steering wheel setting?

Anyone change their engine air filter (not cabin) ? How much the original filter cost?
