10W40 may be Problem Oil |

My understanding of multiweight oils is that they are basically the smaller number in weight, and then have additives to make up for the higher number. 10W40 is particularly high in additives, and that Ford at one time wouldn't honour warranties for people who ran 10W40. 10W30, or 20W50 are supposed to be more stable with regards to the additives breaking down. Now, this could be all hogwash, but I didn't make it up. And even more strange, I think I'll run 10W40 anyway. Thanks for the input guys. |
