    Looking through my owners manual for my new Lazer 26efi Kohler I see no mention of using straight 30wt. oil. The graph chart seems to show only multi viscosity oils. I've always used straight 30 thinking it would have less tendency to break down during the hot summer. I've run the 30wt. oil in all my Kawasaki engines. Should the Kohler be any different.?

    Lazer 46,

    Thanks for the post. This is a question we often get. The Kohler engines use hydraulic lifters and require multi-weight oil. All other manufacturers use solid lifters and recommend a straight 30 weight.

    Often the Kohlers will tend to have a great deal of lifter noise, rattle and in extreme cases knock when consistently run on a straight 30.
