Dakota Generator recommends high quality synthetic oil for our frigid environment. Our service contracts are formed with using Amsoil synthetic 10w-30 small engine oil.
Our current cost per quart of the 10w-30 synthetic small engine oil is $10.05 per quart.
Dakota Generator is also an Amsoil distributor and can provide any Amsoil products.
Generac oil change intervals vary per unit so check your owners manual for your drain intervals and capacity.
