Great stuff, repeat customer.

Why wouldn't you buy your fuel additive from a company that actually produces fuel system components? Not only that, but if you do some research, this is the only company that's endorsed for use in GM Diesels. This stuff seems to be very very expensive where I live. So this is the best price/shipping for me. Can't go wrong. Where's my kitkat? lol

Stanadyne additive

I've only used 1 bottle of the diesel additive, so far no complaints !

It seems to help

I drive a 2008 F450 with 6.4l powerstroke diesel power. Between the size, weight, and low gear ratios this unit is a fuel hog. Since buying the truck used I have brought the maintenance up to a higher standard and on the recommendation of my mechanic started using Stanadyne diesel fuel additive. Between improved maintenance and using Stanadyne I have improved fuel consumption from 22 l/100 Km to 17 l/100 Km and the truck is running great. Because I made so many changes I can’t attribute improvements directly to Stanadyne but it seems to be a good part of my overall vehicle maintenance plan. I will start using it in my BMW X5 335d to see what difference just using Stanadyne makes.
