For what you pay for FEO now, it does not give good protection for the money you pay. You are better off getting Edge 5w-30 when there is a sale on for $35 per bottle and using that with 5k intervals. FEO is only a mineral oil. It won't be able to compete with even a cheap group III synthetic like Edge 5w-30.
