Low fuel efficiency of 1.8 engine and cracking noise comes out at the ignition- Why?
Recently I bought Toyota Allion 1.8(engine capacity) -2008 model. Although most of the time I try to run while the green eco light is on, the fuel efficiency drops below 8km/l ( around 7.5) as it indicates. But to my knowledge Allion has good fuel efficiency. Can 1.8 engine have such lower fuel efficiency? Is something wrong with the engine? My second problem is when the push button is pressed at the start, engine starts but at the same time a cracking noise comes out from the starter motor. What could be the reason for it and how could I rectify this problem. This noise does not come out at subsequent starts which could happen in between short time intervals. Can someone answer for these questions please?
