Actually it ends up being Delvac Extreme 15w-40 which is on the Ford spec approved list. I missed the return date so I will proceed as planned. Thank you for all the responses. Tha Schaeffer is Synshield Durability advantage 15w-40. So I need to practice reading!
Have 3 gal Schaeffer9000 Synshield want to mix 5 qts into 2.5 gal Delvac Super for the next couple oil services on a ‘20 6.7 Powerstroke. Is this ok for 5k miles or do I just run one or the other? TIA
