Octane booster for improved engine performance An additive that increases the gasoline's octane number (RON), which enhances the fuel's resistance to auto-ignition and knocking. The higher the octane number, the better the combustion and more efficient engine operation. When using Omicron 954, the engine responds faster to throttle and delivers better performance. The product only improves the properties of gasoline and has no cleaning functions in the fuel system, except that it contributes to cleaner combustion and thus reduced emissions. Compatible with all types of gasoline. Gasoline: 1:200
