Following the big demand from all the drivers around the world, we’ve decided to develop a special pre run fuel, especially adapted for the first rounds of your brand new engine.
During the break in period, the internal parts of the engine suffer from important friction due to the very precise adjustment of micro engine parts.
Because the engine is brand new, this one have to be adjusted very rich and as a result, is always low in temperature.
This new RB break in fuel include special oils and additives making the lubrication of the engine better at lower temperature.
After 2 liters of the RB pre run fuel, your engine will be in perfect condition to be used with normal fuel and will last longer, thanks to a very good break in.
Available in 2 liters 16% nitro for .12 engines & in 2 liters 25% nitro for .21 and .28 engines.
