* Engine Size is Only Part of the Equation: While the 4K engine is a key factor, fuel efficiency is heavily influenced by many other variables:
* Vehicle Model and Weight: A 4K engine in a small, lightweight car will be much more fuel-efficient than in a larger, heavier vehicle.
* Driving Habits: Aggressive acceleration, frequent braking, and high speeds significantly increase fuel consumption.
* Road Conditions: Traffic, hills, and weather all affect fuel efficiency.
* Maintenance: Properly tuned and maintained engines use less fuel.
How to Find Your Car's Fuel Efficiency:
1. Check Your Owner's Manual: The most reliable information is found in the manual for your specific Toyota model.
2. Look Up Fuel Economy Ratings: Websites like the EPA (US) or your country's equivalent provide official fuel economy ratings for different vehicles.
3. Calculate Your Own Fuel Efficiency: Fill your tank completely, reset your trip odometer, drive normally, then refill your tank. Divide the number of kilometers driven by the number of liters used to get your L/km.
Remember: Fuel efficiency is a dynamic factor. The figures you find will be estimates, and your actual fuel consumption will vary.
