The Bajaj Pulsar 220F has an engine oil capacity of approximately 1150 ml (1.15 liters), as stated in the manual. However, it's important to note that the oil gauge may not always show the exact amount of oil in the engine.
When checking the oil level using the oil gauge, it's recommended to ensure the motorcycle is on level ground and the engine has been warmed up and turned off for a few minutes to allow the oil to settle. Then, remove the oil dipstick or oil level window and wipe it clean. Reinsert the dipstick fully or check the oil level through the window, making sure it is securely in place. Remove the dipstick or close the window and check the oil level against the indicated markers or the "Full" line on the dipstick.
If the oil gauge shows "full" with only 1 liter of oil, it's possible that the gauge may not be calibrated accurately or there could be variations in the design or measurement. It's generally safer to follow the manufacturer's recommended oil capacity (in this case, 1150 ml) to ensure the engine is adequately lubricated.
If you have any concerns or doubts about the oil level or capacity, it's advisable to consult an authorized Bajaj service center or a qualified mechanic who can provide accurate information and guidance based on your specific motorcycle model.
