No but they do have a 5w40, 10w40, and 5w30. You don't really have to have 10w30. They say the quality and protection of the oils are so much better than other synthetics that they don't even try to compete in that market. They are offering the best quality and protection regardless of cost (expensive). Considering who they have backing their product I think Im sold.. I just wanted to hear everyones experience with them.
