While mineral-based oil is a cost-effective option, it generally provides lower performance compared to synthetic alternatives. It is recommended for older 2-stroke engines or engines with lower performance requirements.

Semi-Synthetic Oil

Semi-synthetic oil, as the name suggests, is a blend of mineral-based oil and synthetic oil. This combination provides a balance between affordability and performance. The synthetic oil component enhances the lubricity and thermal stability of the oil, while the mineral oil component helps to keep costs down. Semi-synthetic oil is a popular choice for a wide range of 2-stroke engines, offering improved protection and performance compared to mineral-based oil.

Fully Synthetic Oil

Fully synthetic oil is the highest grade of 2-stroke oil available. It is formulated using a complex blend of synthetic base oils and additives, resulting in superior lubrication and performance characteristics. Fully synthetic oil offers excellent protection against wear, reduces carbon deposits, and enables engines to operate at higher temperatures. This type of oil is recommended for high-performance 2-stroke engines, including racing motorcycles, jet skis, and chainsaws.
