Dumonde Tech L111 Synthetic Two Cycle Racing Oil
Dumonde Tech L111 Synthetic Two Cycle Racing Oil is a premium, multi-latitude 100% synthetic lubricant engineered to deliver superior performance and maximum protection for high-revving racing engines. Widely regarded by racers as the best 2 stroke oil for go karts—specifically the demanding Rotax Max class—L111 is formulated to outperform standard synthetics, making it the ultimate choice for competitive and recreational riders who demand elite engine cleanliness.
Whether you are looking at 2 stroke oil injection vs premix setups, L111 settles the debate by adapting seamlessly to both delivery systems without sacrificing film strength.
Why Racers Choose Dumonde Tech L111:
-
Dumonde Tech L111 vs DTP (No Re-Jetting Required): Unlike Dumonde Tech’s DTP oil, which requires leaning out your carburetor, L111 is a true plug-and-play formula. It offers elite synthetic protection without forcing you to change your spec jetting or carburetor settings.
-
How to Stop 2 Stroke Spooge: If you want to know how to stop 2 stroke spooge, this is your answer. L111 is engineered as the cleanest burning 2 stroke oil on the market, keeping power valves, rings, and piston crowns entirely free of sticky carbon buildup in both low and high-ratio applications.
-
Engineered for High-RPM Small Bore Motors: Specially designed for high-revving racing motors where crisp, reliable throttle response is the difference between a podium finish and a DNF.
