Good evening,
The mobile website has the mobile delvac 1300 super in a 10w30 wt.I can only find it in a 10w40.Please help.I have moved back to Tennessee, Still no luck. Thanks, Jack.
You will likely have to order it from the local distributor as the 10W-30 is very difficult to locate. The 15W-40 is required for most HD Diesels.
