Avoid peak traffic hours.
Info
Fill the tank completely, reset the trip meter, drive normally, then fill again. Liters used / km driven x 100 = your L/100km consumption. Average over several fill-ups for more accurate results.
Diesel cars generally consume 20-30% less fuel, but diesel prices are close to gasoline. If you drive 20,000+ km annually, diesel may be economical. LPG is most economical for city driving due to its much lower per-liter price.
Looking at fuel cost alone, driving is typically 3-5x more expensive than public transit. When insurance, maintenance, parking, and depreciation are added, the gap widens further.
