At Omnia Racing you can purchase engine oil for motorcycles and scooters, with solutions dedicated to 2-stroke engines, 4-stroke engines, road use, touring, urban riding, sport riding and racing applications. Popular viscosities such as 10W-40 and 5W-30 must always be selected according to the manufacturer’s specifications, engine type, climate conditions, intended use and the presence of a wet clutch system. Using the wrong oil may negatively affect gear shifting, clutch operation, engine temperatures and long-term durability.

Among the brands most appreciated by riders you will find Liqui Moly, one of the most trusted names in the motorcycle and scooter world thanks to reliable lubricants available in multiple viscosities for daily use, sport riding and track applications. For the scooter segment, Malossi offers dedicated 2T and 4T engine oils, including road and racing solutions designed for riders looking for performance, protection and compatibility with both stock and tuned engine setups.

Choosing the correct motorcycle engine oil means protecting internal components such as pistons, connecting rods, camshafts, valve train systems, gearboxes and clutches. On more demanding engines — such as tuned scooters, sport motorcycles or track bikes — lubricant quality becomes even more important because the engine operates at higher temperatures and RPM levels. Regular maintenance with the correct oil helps preserve performance, reliability and engine lifespan over time.

Motorcycle engine oil viscosity grades and correct selection

When choosing a motorcycle engine oil, you may find labels such as 5W-30, 10W-40, 10W-30 or 20W-40. These numbers indicate the oil’s viscosity at cold and operating temperatures, meaning how the lubricant behaves under different thermal conditions.

The first number, before the letter W, indicates the oil’s viscosity at low temperatures. The W stands for Winter. An oil with a lower first number, such as 0W or 5W, flows more easily when cold and can provide faster lubrication during cold starts. For this reason, oils such as 5W-30 or 10W-30 may be more suitable in colder climates or winter conditions, always following the motorcycle manufacturer’s specifications.

The second number, such as 40 or 50, refers to the oil’s viscosity at normal engine operating temperature. The higher this value, the more the oil maintains its viscosity at high temperatures, offering greater protection when the engine is under heavy thermal stress. For everyday riding, mixed routes and leisure use, grades such as 10W-40 and 20W-40 are among the most common in the motorcycle and scooter world because they offer a good balance across a wide temperature range.

Which engine oil should I choose for my motorcycle?

Motorcycle engine oil must be selected according to the manufacturer’s specifications, recommended viscosity grade, engine type and intended use. Grades such as 10W-40 and 5W-30 are very common, but they are not universally suitable for every motorcycle.

How often should motorcycle engine oil be changed?

Motorcycle engine oil should be replaced according to the intervals specified by the manufacturer, usually every 4,000–5,000 km or once per year. In case of sport riding, track use, tuned scooters or intensive riding conditions, earlier maintenance may be advisable to maintain optimal protection and performance.

What is the difference between 2T oil and 4T oil?

2T oil is designed for 2-stroke engines and becomes part of the combustion process, while 4T oil lubricates the internal components of a 4-stroke engine. They are completely different products and must never be interchanged unless explicitly specified by the manufacturer.

Should I also replace the oil filter when changing engine oil?

Yes, it is necessary to replace the engine oil filter during every oil change. This prevents the new lubricant from being contaminated by impurities trapped inside the old filter.
