Engine oil is one of the most important lubricant a motorbike engine needs. Engine oil plays a vital role in the smooth running of the engine, reducing fuel emissions, and improving engine’s performance.

If the bike is used regularly, then the oil level needs to be checked at least weekly. Though it’s always best to use the handbook for guidance, there are some steps that can be followed to check engine oil levels. Motorcycles either have a dipstick or an oil sight glass.

In case of sight glass, look at the window located at the bottom of the engine to make suer the oil is between
the two marks on the case, but towards the maximum level.

For engines with dipstick, check the owner’s manual to make certain how the stick is to be inserted for an accurate reading, Usually, the stick has to be wiped and inserted into the case until it makes contact with the filler plug’s threads. Be sure the plug is straight and the bike is level or there are chances of inaccurate reading.

Never check engine oil level with a hot engine unless the manufacturer states this is the case. The reason being a greater amount of the engine oil will still be in key parts of the engine until it drains down back into the engine sump/reservoir/lower cases. Topping up a hot engine can lead to overfilling the engine and cause other problems; the usual is excess oil being fired out under pressure into the air-box.

Checking the color texture

• If oil is dark or black, it indicates that the oil needs to be changed
• If oil is milky white, it indicates that the coolant has found its way into the oil, which could indicate a blown head gasket and/or a major engine problem
• If the oil smells like gas, take it to the mechanic
• If the engine has suddenly begun consuming oil, it could mean valve or piston-ring problems, which require investigation to ascertain the cause.
