Viscosity rating

If you’re looking for the right type of motorbike oil, there are several things you should look for. The viscosity rating of a motorcycle oil can make all the difference in how smoothly it shifts and performs. Whether you’re looking for a synthetic blend or a conventional one, the viscosity rating is important. Motorcycle oils come in a range of viscosities, and a higher viscosity number means a heavier oil will be necessary.

Motorcycle oils are usually formulated for specific models, but there are a few universal types that can be used on almost all bikes. The 10W-40 oil is the most popular choice for heavier duty gasoline engines, as it offers better protection against thermal breakdown. Motorcycle oil in this type has high viscosity, which means that it is less likely to leak, even when it’s hot. It is also a good choice for high-temperature conditions because it’s thicker than most standard motorcycle oils.


When you’re buying the best motorcycle oil for your motorcycle, you want the one that meets the highest standards. Royal Purple, for example, is a brand that’s synonymous with quality, performance, and longevity. This premium oil is known for its price, but is a reliable choice for those who ride motorcycles frequently. Mobil, meanwhile, has been making 10W-40 engine oils for over a century.

Motostar SAE 10W-40 motorcycle engine oil is suitable for both dry and wet clutch applications. It uses a combination of premium petroleum base stocks and advanced trimetallic additive technology to ensure a stable viscosity. This multi-grade oil is also designed to reduce friction and wear. Motoglym has long been a trusted brand of motorcycle lubricants. Its premium 10W-40 motorcycle oil is also made in the US by Maxima Racing Oils.

Longer working life

The Mobil 1 Racing 4T 10W-40 motorcycle engine oil delivers maximum power output with strong synthetic technology. Its lubricating properties are perfect for wet clutch applications and reduces friction to help the engine operate at optimal efficiency. Its viscosity is stable, so it will not cause engine wear and tear. Its anti-wear and anti-scuff agents reduce friction and ensure a smooth engagement of the clutch. Moreover, the Mobil 1 Racing 4T 10W-40 engine oil is highly recommended for its high performance in all seasons and environments. Its high-performance formula prevents engine damage and improves performance.

Another benefit of using Mobil 1 Racing 4T 10W-40 motorcycle oil is its extended-life, long-lasting performance. The oil is fully synthetic and can last for up to 1,000 miles. It features high zinc and phosphorus levels, which help the engine shift smoothly and produce trouble-free performance. This motorcycle oil is formulated to deliver superior engine protection at a lower cost. But, it is not suitable for all bikes and motorcycles. To ensure proper performance, it is important to follow the recommended maintenance schedule for the engine.

Synthetic oil

Motorcycle owners will find that a quality synthetic motorcycle oil is an excellent choice for their vehicle. These oils provide optimal performance and are formulated for use in both foreign and domestic 4-stroke engines. They meet API service classifications and offer superior protection against high temperatures. The high quality of these oils is further improved by the presence of Synerlec additives, which enhance oil shear properties and film strength. Additionally, they can expect longer drain intervals. This oil also meets API viscosity specifications.

Motorcycles are susceptible to rust caused by high-rpm operation, humidity, and short-drives. Rust can lead to major engine damage, causing uncontrolled wear, blow-by, and compression loss. While engine oils naturally offer protection against rust, synthetic motorcycle oils have special anti-rust agents that prevent rust formation. These additives also maintain internal engine cleanliness. Synthetic motorcycle oil 10w40 helps prevent these problems and will keep your motorcycle running smoothly.
