Tips for incresing mileage are as follows: -
1. Do not rev your car/motorcycle on higher rpms as it increases the fuel consumption rate
2. Switch off ignition at red lights if the red light is of more than 40seconds
3. Get your service done on time as wear/tear and overuse of oil filter, air filter, engine oil as it also adds to overuse of fuel and also decreases engine life
4. NEVER drive/ride your vehicle on half clutch ( holding clutch lever or pad at half level after gear shifting)
5. Shift gear only when necessary ( the gear shifting process should neither be too fast or too slow)
