I guy I work with has a 2002 Chevy Duramax and he is running FPPF Total Power. This has Cetane boost and reduces gelling in the winter. He runs it all year round 4oz per tank in summer and 8oz per tank in winter. 82,000 miles on his truck and no issues to date. He isn't a dealer or anything but this is what he trusts.
I was wondering if anyone tried it in a newer 6.0 PSD and got any results.
Thanks,
