I use Stanadyne Performance (Blue label) and Lubricity (Purple label) - combine my own mix for a long-bed (48 gal), since owning Aug 19. Per Stanadyne's site - formulas can be mixed, peace of mind and available at TSC.

Standadyne is better than nothing, but they didn't do much in the old Spicer study. I definitely wouldn't cut the Lubricity formula with the Performance blend. You want everything that the former can give you, as the latter does almost nothing for lubricity. I'd use Stanadyne in a pinch. But, for something that gave me a legitimate lubricity improvement, I'd look elsewhere.

I’m a big Schaeffer’s fan and would like to use carbon treat but I haven’t found any data on the lubricity benefit of it.

In the garage, I have Power Service, Standadyne, and Opti-Lube XPD. I have used PS in the 02 for as long as I can remember. Never had an issue but I think these newer trucks are more prone to issues than the older models. For the 19, I am going to stick with XPD so I don't need to worry about changing the additive depending on the weather. Our Diesel Cetane rating is CA is higher than average so the additional bonus of the XPD is not really needed and while the XL formula appears to perform better in lubricity, I would rather have the higher water demulsifier in addition to lubricity. The anti-gel is a bonus so I don’t need to switch it over when I decide to drive up to Wyoming in the winter.

The only test I’ve ever seen is the spicer study from over ten years ago. It was good, but only tested a free brands. I have personally used the different Redline products, Optilube Summer, and Power Service silver bottle. I wish there was a more recent and comprehensive test.

i have been using carbon treat for over 6 years now with motors with over 8k hrs with no injectors problems or pump. I’m over hrs on dpf filters that should of needed replacement. I have one tractor that I drive only that has never needed a manual reburn from what I’m told it’s unheard of with 1900hrs on it.

You asked the exact same question 2 months ago. Are you expecting a different results?
