What oil does a 25 hp Kohler engine take?
10W-30 Oil
Can I use 5w30 instead of 10w30?
Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.Oct 2, 2021
