Hi romack, If the temperature where you live changes drastically during the winter months you would be smart to change your oil to something thinner. For instance, if you typically use 10W-40 you might try using 15W-40 during the winter months. If this is the problem you've been driving on "thicker oil" for the last several months possibly causing internal damage with every stroke of the piston. Hope this helps!
the company recomends 5w30 in this engine
