When it comes to lubricating lawn mowers, chain saws, string trimmers, outboard engines, personal watercraft, motorcycles, scooters, portable generators and snow blowers, there’s one motor oil that does it all. Valvoline Multi-Purpose 2-Stroke Engine Oil is specially formulated for most high-revving, small 2-stroke engines, air-cooled and water-cooled engines, pre-mix and injection engines as well as engines requiring a gas-to-oil mixture. And it meets outboard or personal watercraft manufacturers recommendation for use of NMMA TC-W3 oil. Its premium base stocks are blended with ashless detergent additives that help protect against rust, corrosion, piston deposits and scuffing while keeping spark plugs and exhaust ports clean for better engine performance. Our formula is pre-diluted for ease of mixing and may also be used in direct injector systems. This oil can be used where manufacturers recommend fuel/oil ratios from 11:1 to 100:1.
