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

Ford OEM approved, good product won't void warranty.
This product is OEM Ford Powerstroke approved, which made me feel better using it in my powerstroke. While no miracle it is supposed to help lubricate the fuel pump, keep injectors clean and it does provide small but noticeable mpg gains especially while towing. It seems to also reduce DEF utilization slightly while towing. It isn't priced crazy and I like feeling as if I am giving every possible protection to that very expensive diesel while staying within warranty by using an OEM approved product.

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?
