What to pay attention to when changing oil

2. It is necessary to drain all the old oil and clean the coarse filter

Old oil contains many impurities and metal shavings that will damage the engine, so it needs to be drained thoroughly. Tilt the vehicle to let the remaining oil in the engine parts flow out completely, then use a steam nozzle to spray the engine block to splash out the oil.

After that, the coarse and fine filters are washed with diesel oil and use a steam nozzle with light pressure to blow all the iron filings and dirt out of the filter and then carefully reinstall them in the correct position to avoid oil leakage. If the vehicle has run 6,000 km, the fine filter should be replaced.

3. It is necessary to choose the right oil for the vehicle type and the right oil capacity of the vehicle

Ma Kim So, a veteran racer who is well known to motorcyclists and a master of motorcycle repair, also said that motorcyclists should use the right type of oil for their vehicle. He analyzed: “Scooters operate hotter, have belt-driven CVTs and dry clutches, so the oil is designed to maximize the vehicle’s performance: fast acceleration, maximum power, engine cooling and reduced fuel consumption, such as Liqui Moly 5W40 Molygen, a synthetic oil for 4-stroke scooter engines. Meanwhile, manual transmission vehicles have gears and wet clutches, so the oil used for these vehicles must have higher friction properties.”

In addition, motorcycle oil is produced in 0.7 liter, 0.8 liter and 1 liter packages to suit the capacity requirements of many different types of engines. Therefore, experts recommend that when changing oil, users should choose the appropriate type to avoid excess or lack of oil. Because a vehicle with too much oil will be heavy, making the engine hotter, while a vehicle with too little oil will lack lubrication, the oil will foam, making the engine hotter, causing more wear and tear.

4. Check the label and seal of the oil

You need to carefully read the label of the oil bottle that you replace for your motorbike, to make sure that you have replaced the right type of oil for your motorbike, as well as the correct oil capacity to avoid wasting excess oil, or not enough oil which is very harmful to the vehicle. Information that users should pay attention to such as brand, product type, capacity, expiration date, … to ensure choosing the right quality product and suitable for the vehicle.

The new oil bottle must be sealed with two layers: a plastic cap and a seal covering the mouth of the bottle. Users need to pay attention to this issue and check the seal carefully before asking the staff to fill the oil into the vehicle. In particular, it is necessary to know where to buy genuine and reputable motorbike oil to avoid buying “fake” oil.

5. Make sure the oil flows evenly in the motorbike engine

After adding new oil, the motorbike needs to be tilted to the left and right for a few seconds to let the oil flow evenly, then press the starter 5-7 times (without inserting the key) to pump oil to the machine parts. Next, open the key, let the engine start for a few minutes before running. Finally, remember to clean the oil stains on the engine to avoid dirt sticking around.

The above 5 important notes when changing motorbike oil will help you a lot in the process of using and maintaining your motorbike for a long time. Basic knowledge about engine oil will help you maintain your motorbike better and help you know when to change the motorbike oil.
