OMG, best oil I have ever put in my '07 6.0 powerstroke F-250. So smooth, responsive and 2.0mpg increase in fuel economy. I use this oil in conjunction with 16oz of Archoil AR9100. Cold start Valve train noise on start up is virtually non existent. Previously, I used Amsoil 10w30 OE diesel oil and valve train noise was common on cold starts for at least a good 5 seconds. I'm very happy with the Delo 400 LE 5w30 diesel synthetic and will run this oil exclusively. I've ran john Deere 10w30 plus 50 II, Rotella, delvac, amsoil.and this is hands down the best oil for a 6.0
