How to Solve High Fuel Consumption in Suzuki Swift?

Insufficient tire pressure and tire wear. Insufficient or low tire pressure will increase friction between the tires and the ground, leading to greater resistance and higher fuel consumption. Regularly clean carbon deposits. Poor-quality gasoline can cause excessive carbon buildup, which roughens the intake pipe walls and increases fuel consumption.

When driving my Swift, I also noticed higher fuel consumption. After checking my driving habits, I realized the issues. Frequent hard acceleration and braking, consistently low tire pressure, and always running the AC in summer. Now I've learned better—maintaining a steady speed, slowing down in advance, keeping tire pressure around 2.3 bar. I turn the AC off for 10 minutes after 30 minutes to give the compressor a break, reducing city driving fuel consumption by over 1L. Also, clearing out the tent and fishing gear from the trunk helps; the car runs much lighter. Don’t overdue oil changes, using 0W-20 viscosity makes it smoother. If problems persist, check the oxygen sensor and spark plugs at a repair shop—those can guzzle fuel like water if faulty.
