So I noticed out of T4, T5 and T6 only the Rotella T5 meets this Ford spec in 15w-40. I could only find one 1.25qt of Motorcraft 15w-40 oil at Wal-Mart. Ended up buying it and a 2.5 gallon of T5. I could use the T5 and finish with the MC meeting the WSS spec but I do not want to mix oil so I will return the MC and pick up 2 1 gallon jugs of Shell T5 15w-40. I do not know if mixing the shell and MC will cause issue's but who knows. If you have a opinion on this matter let it be known.
I wonder why T4 and t6 dont meet the specs? I guess I will just stick with the T5 as since the MC says it meets new spec. I cant find anymore MC 15w-40 for some reason? If I knew 10 Quarts of Rottela T5 15-40 with 5 quarts of MC 15w-40 would be fine I would just use it this go around.
