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
