Translations:KAVAN FT160AR - Instruction Manual/54/en

For consistent performance and long life of the engine, it is advisable to use good quality fuel containing MORE THAN 16% LUBRICANT until a total of one to two hours running time has been accumulated including the running-in period. Generally, the fuel containing a lower lubricant content improves the running characteristics of a four stroke engine slightly, but it may also shorten engine life.
