Benzol 10W-40 1.3L refers to a premium, fully synthetic 4-stroke motorcycle engine oil (marketed as Benzol Moto Racer) packaged in a 1.3-liter container.  
​Viscosity Grade (10W-40): The 10W rating provides smooth cold-starts and quick oil circulation in lower temperatures, while the 40 rating maintains a thick, protective film at high operating temperatures and heavy loads.  
​1.3-Liter Volume: This specific 1.3L packaging size is particularly popular for certain high-capacity or specific models of 4-stroke motorcycles (such as certain 150cc to 160cc bikes) that require slightly more than the standard 1-liter capacity during an oil change.
​Technology & Formulation: It utilizes advanced synthetic base oils—often leveraging Molecular Converted (MC) or ester-based technology—to minimize thermal breakdown, reduce clutch slippage, and control engine sludge.  
​Specifications: Typically meets high-tier international standards such as API (up to SN/SP) and JASO MA2 (ensuring proper wet-clutch friction performance for manual-transmission motorcycles).
