What oil would you recommend for 10K oci on a 2015 Toyota Highlander? This highlander sees mostly short trips (5-15 miles) monday-friday and some longer trips on the weekend. I personally don't like 10K OCI especially with such short trips but my father in law religiously follows the "maintenance required" light which comes on at 10K on the Highlander. He has been using Amsoil XL and a wix filter, I told him there is plenty of oil you can get at walmart for much cheaper. Would oil would you recommend in this case?
