Optimise the performance and extend the lifespan of your small engines with Opti, a premier brand of high-performance lubricants engineered specifically for the demands of outdoor power equipment. Developed by Interlube International, Opti’s signature range is celebrated for its cutting-edge formulas, including the highly popular Opti-2 and Opti-4 engine oils. For two-stroke machinery, Opti-2 provides a specialised, single-mix solution that meets or exceeds stringent global standards, simplifying fuel mixing across all your two-cycle equipment regardless of the manufacturer’s original ratio. For four-stroke engines, Opti-4 utilises patented Eutectic additive technology, which works on a molecular level to smooth out metal surface roughness, significantly reducing heat, friction, and internal wear. This advanced technology ensures smoother operation, lower operating temperatures, and cleaner emissions, making it an environmentally friendly choice that handles modern ethanol-blended fuels with ease. Whether you are running chainsaws, line trimmers, or lawnmowers in demanding Australian conditions, Opti lubricants deliver reliable protection that helps prevent carbon build-up and engine degradation.
