Hello guys,
I need help, I have a 1500cc 2016 Toyota Axio hybrid WXB with 89,000km on the ODM. The hybrid system kicks in and works really well. Here is the problem, the petrol engine guzzles a lot of fuel to the tune of 2km/l. This happens whenever the car is running on the petrol engine, even in idling the display shows the fuel consumption at below 5km/l, images attached for reference. The car moves really fine and on a highway i get an average consumption of 22km/l at best that's after driving very "carefully and responsibly" making highway driving really slow (80-100km/hr).
I have changed spark plugs, used the recommended engine oil (0-20W), replaced the fuel filter and done full service but the problem persists, I've gone to several garages and all keep recommending i change the same parts which is frustrating, could it be an engine problem? can someone help on how i can troubleshoot this issue?
FYI
Compared to another Toyota Axio hybrid at 120,000km ODM, my car's engine sounds heavier n more rough. (In my Axio I do at best 22km/l in the other Axio I causally did 28km/l without careful and responsible driving and over 30km/l when careful.)
Help needed,
Ronnie
