OPTIMIX-15MV 4-stroke with 15% nitro & 20% oil utilizes medium viscosity oil from KLOTZ, which is 275 centistokes unlike our OPTIMIX-4-stroke range which uses 75 centistokes oil from KLOTZ. This is ideal for users of four-stroke engines that have been used to a more ‘traditional’ blend of fuel. This works well in Saito’s, RCV and other four-stroke engines including OS. Not ideal for two-strokes but will operate satisfactorily and we would suggest YS four-stroke users use the standard OPTIMIX-20 or 30 four stroke mix.

OPTIMIX-15MV 4-stroke is a good choice for scale where power is not ultimately required.

As with all OPTIFUEL™ blends the fuel is supplied in 5 litres jerry cans not 3.78 litres or 4.5 litres as per our competitors.
