this is my wife's 05 tundra double cab 4.7l v8
i changed the factory fill out at just under 1000 miles w/ castrol gtx 5w30 and just changed it again w/ 3k miles on the engine. i put in shaeffer's 5w30. i now plan on starting 5000 mile oci's (per toyota warranty) w/ analysis at least for the first few changes.
what's the general concensus, is it still to soon for a 5000 mile oci?
