The 2022 Honda Civic has a fuel tank capacity of approximately 47 liters. In Malaysia, using RON 95 petrol, with the current fuel price around RM2.05 per liter, a full tank would cost roughly RM96.35. The actual cost may vary slightly due to fuel price fluctuations and regional differences. It's important to note that fuel efficiency is affected by driving habits, road conditions, and vehicle maintenance. For example, aggressive driving or frequent traffic jams can increase fuel consumption, while regular maintenance like changing the air filter and maintaining proper tire pressure helps optimize fuel economy. Malaysian car owners can also further reduce fuel consumption through Honda's eco-driving assist features such as ECON mode, and it's recommended to use common local apps like MyTukar or Fuelly to record fuel consumption data. Long-term tracking allows for a more accurate understanding of vehicle operating costs. Additionally, the fuel tank capacity may vary slightly across different years of Civic models, so it's advisable to check the specific specifications before purchasing a car.
