Great Product Highly Recommend for Diesel Engines
I use my oil sampling program to test this product.. After using Stanadyne the iron count in my oil sample decreased. To double check it I did not use it for the next oil change cycle and the iron count went back up. I used Stanadyne no treatment to the next oil change cycle and the iron count went back down. Definitely a good product to lubricate your fuel system and reduce wear on your engine

Stanadyne does not provide the results of HFRR results for this additive. Contacted them HFRR data - they answered that they outsourced additives to a different company (Parker Hannifin) and I should contact them. In my opinion if you name is on the bottle you should now stuff about it, or redirect the request accordingly, not to football people. According to Spicer Report on lubricity improvement additives this additive makes a tiny improvement: -33µm for values 350-400µm. Under 10%. Did not see data for cetane improvement. Bought lubricity formula from Opti Lube, will probably switch to them for Performance formula too. But not a bad product per se.

Great stuff
Been using this ever since sulfur got pulled out of marine diesel. Engine is happy, old school injectors are happy, and it hasn’t clogged my diesel heater. What more could you ask for in a fuel additive?
