RTR Power

As an RC Car hobbyist you want to enjoy running your cars and trucks, not worry about engine settings.So you want a fuel that simply delivers: power, engine protection, easy starting, long engine life and ease of use - basically a reliable power source for your car.

Easy tuning

The Optimix RTR blend is formulated for easy tuning in all temperature ranges for engines of all sizes. Optimix-RTR was developed especially for today' RTR nitro engines. The specific blends use the same high quality synthetic oils as our Optimix-Race blends. Optimix RTR makes starting and tuning your engine
easy because its specific blend is more tolerant of incorrect settings and of temperature and humidity changes. The consistent burning provides a steady smoke trail allowing you to easily see the effects of your engine tuning.

Protect your engine

Optimix RTR burns cleanly, leaving no harmful residues that increase wear and
decrease engine performance and lifespan. The oil in the fuel provides protection from corrosion to further extend your engine's life.
