Delvac 1 5W40 currant stock on the shelf is rated API service, CK-4, CJ-4, CI-4plus/ ACEA E9,E7.
It is also rated SM/SN but is not labeled on any of the containers, jugs, or pails. It has been rated SM/SN for years, they just don't seem to want to label it for some reason. Whatever that reason is? It does not make any sense! You can only find that SM/SN spec on the Delvac website.
I will go look for the $10.00 per jug discount for you. I got my rebate in 2/3 weeks, its separate from Mobil 1. So if you did a Mobil 1 rebate, you can do a Delvac rebate also.
