How Much Engine Oil Should Be Added to a Underbone Motorcycle?

An underbone motorcycle typically requires about 800 milliliters of engine oil per refill. The oil quantity for underbone motorcycles is generally around 800 milliliters, which can be verified using the oil dipstick or oil inspection window. Checking the Oil Level: When changing the oil, park the motorcycle on a level surface using the main stand. Remove the drain screw at the bottom right side of the engine to drain all the old oil. After reinstalling the drain screw, add approximately 800 milliliters of new oil. Insert the dipstick into the dipstick hole (push it all the way in without screwing it in), then remove it to check that the oil level is between the upper and lower marks at the end of the dipstick. Choosing a Suitable Oil Container: During hot seasons, even when using a fuel pump to fill a container with gasoline for refueling a motorcycle parked in a designated refueling area, it is essential to use a conductive container made of materials like iron or aluminum. Plastic containers must not be used as oil containers, as they can easily cause static electricity reactions, leading to fires.

As a veteran rider with over a decade of experience on underbone motorcycles, I must say the engine oil capacity can't be generalized. There are significant differences between various underbone models. For common small-displacement bikes like Honda underbones, it's typically around 0.8 to 1.0 liters, but my old motorcycle's manual specifies 1.1 liters. The most important thing for beginners to remember is to check the dipstick: After warming up the engine and waiting a few minutes, wipe the dipstick clean and reinsert it - the oil level should be between the MAX and MIN marks. Too much oil causes smoking and carbon buildup, while too little leads to engine component wear, which is troublesome to repair. Whenever I do DIY maintenance, I always start by adding 0.7 liters first, then gradually top up to the upper limit. Regular oil changes are even more crucial - using 10W-40 full synthetic oil provides better engine protection, and for city riding, changing every 3,000 kilometers is sufficient.

When repairing motorcycles, I often encounter many underbone bike owners carelessly adding engine oil, leading to safety hazards. Safety first—ensure the engine has cooled down before adding oil and check the standard amount in the manual. Most underbone bikes require 0.9 liters, but checking the dipstick is the most reliable method. Adding too much oil increases pressure, damaging seals and causing leaks; too little leads to insufficient lubrication, loud friction noises, and shortened engine life. The steps are simple: unscrew the filler cap, add a small amount, wait five minutes, then check the oil window or dipstick to ensure it's at the midpoint. Check the oil level monthly to avoid breakdowns on the road. Always use motorcycle-specific oil—avoid car oil, as its higher viscosity can cause issues.

When I first bought my underbone motorcycle, I didn't know how to add engine oil. A friend told me that a regular small underbone typically needs about 0.8 liters. Later, when I did it myself, I noticed the bike had an oil window. After parking on level ground and letting it cool, I found the ideal oil level is between half and two-thirds of the window. The simple procedure is: first, unscrew the drain plug to remove old oil, then add new oil up to 0.9 liters (a common amount), wait a few minutes, and check the oil level. Don't pour too much at once, or it will overflow and dirty the bike. Change the oil regularly every 2,000 kilometers, using 10W-30 grade oil, which is suitable for city commuting. Beginners can ask a fellow rider for help to learn—it only takes a few minutes once you're familiar with it.
