Easy there tiger, based on your other replies I’m betting you’re already gone. We don’t need hot shot know it alls.
Do I know every single formulation change they’ve made in the last decade? Hell no, but I can tell you I’ve seen OptiLube XPD cause some weird runability issues on a few high hp trucks. I used it for years until I got tired of the costs.
I then switched to 2 stroke oil like many others for lubrication.
More recently we’ve been running Hot Shots EDT in all our shop vehicles and noticed a touch better cold start performance.
To me, the biggest reason to run an additive is lubrication. The early fuel systems were never designed for ULSD that we have today so to me adding back that missing lubrication does only good things and prolongs fuel system life.
