I run Hot Shots EDT as well and was really surprised at how much difference it made. Very cost effective per dose, I happily run it. There's no premium diesel around here.
Smoother, less combustion event noise, throttle response improved so much that I had to recalibrate my right foot.
Caveat: I drive an old school IDI mechanical diesel, more in common with antique farm equipment than a modern engine. None of this may apply to new stuff, but a small bottle is every inexpensive to try. I'm careful to measure exactly, not just eh glug glug good enough.
I agree. The manual for my 3.0 duramax even says to use an Additive if top tier isn’t available. Since I bought it new 90k miles ago I’ve used Stanadyne, Hot Shot’s, and Archoil for a few tanks until I realized it had iron in it. Current plan is to finish up my current HS bottle and then switch to optilube and mix their XL and boost offerings.
