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

Great stuff
Been using this ever since sulfur got pulled out of marine diesel. Engine is happy, old school injectors are happy, and it hasnโt clogged my diesel heater. What more could you ask for in a fuel additive?
