"Seeing this F-350 go from a cold-blooded, rough-running basket case to a truck that ran as smooth as it did the day it left the dealership definitely made believers out of us."
"Archoil is the Real Deal"
This stuff is amazing just change the oil and add the Ar-9100 and no more missing. When this engine was new it would miss spit and spudder cat replaced the injectors fixed it for a short time and then back to missing, got some Ar-9100 and put added it to the oil and solved all the issues. This stuff works.
This product worked great and the check engine light went off! WOW
I was told about this product by a diesel mechanic to add to my 6.0 do to my injectors acting up I am amazed as to how quick it fix the issue that I was having I will definitely be putting it in each oil change to continue the service on my truck. Thank you for a wonderful experience.
I use archoil every time I change my oil in my truck. It is a great additive.
Archoil products do what they say ... I have 378,000 miles on my ‘99 7.3 Powerstroke and it runs better than it did new. GL. Acton, Ca
