1.5 STIHL 4-MIX engine
The 4-MIX engine works with mixed lubrication. 
Unlike a conventional four-stroke engine, the 4-MIX 
engine does not have any supply of oil in the 
crankcase. The engine is lubricated entirely with a 
mixture of petrol and engine oil.
This design yields the following advantages:
. Same fuel
. Lower fuel consumption
. Can be operated in all positions
. Fewer emissions
. Good acceleration
. Compact size – attractive design
. Advantageous power-to-weight ratio
. Easy maintenance – easy to service
. Pleasanter sound – lower noise level
. Fewer vibrations
. Lower starting force
