> 3 daySo, I started using this product in my fleet since the Supreme 9000 5W-40 CJ-4 is not recommended for newer EGR/SCR equipped vehicles. Two things Ive noticed: 1. The oil stays cleaner much longer 2. The buses use much less DEF. Because this is made by Schaeffers, I trust that the durability will hold up and keep my equipment running for many miles.
