Any oil recommendations for an 08 with 100k on the motor? Use to run Rotella 0w40 in all my VW diesel and it worked great...was wondering if it would be a good oil for the my new to me 08 F450.

 

Since you are in Canada you will want a syn. for the colder winters. Hopefully some of our other owners from the far north will chime in.

regardless you must use a diesel oil and it must be CJ4 rated. As long as it meets that requirement then it is worthy of consideration.

 

Actually I looked this oil up when I saw this, actually looks impressive. Toyota and other manufactures I have seen have gone to this 0W style synthetic oils and claim improved fuel mileage. I just might have to try it!
