Default Re: 30w oil

Good evening!

These motors are unsuitable for low viscosity oils. The large installation tolerances require a thick liquid oil to maintain a hydrodynamic lubricating film in the crankshaft bearings.
In addition, a low-viscosity oil leads to increased oil consumption and the combustion residues in the combustion chamber got too much.
