Product is great. I used it in my 6.0 and continue to use it in my 6.7. I use the Archoil products in all my vehicles. Only issues I've had is with shipping. Every time my order is lost, damaged, or delayed. Customer service always handles arrordinly but please use someone other than the USPS.

Great Product!

There was a clear difference in the way my 7.3 started and ran, after the first couple tanks it started much easier in colder weather and it even sounds quieter too. The pedal response drastically improved as well.

Great products

I use in all of my diesels. My 99 Ford, 06 Dodge, and my 14 VW all run better. Plus the lubcation helps protect my 14 VWs CP4 HPFP as well as prevent sticking of my Fords Huei injectors. Great product for any diesel engine. 100% recommend.
