"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"
First used this after finding nothing but positive reviews. Used it on my bad injectors and it saved them until I could get new ones (almost a year) and even with new injectors I use this stuff every oil change because it works great.
I have been using Archoil products for a number of years and the products seem to do what they say. Shipping was timely.
Product is great, customer support OK, but a bit slow
After getting oil changed and adding Archoil, injectors quieter on cold start ups. Have used 9100 in past, but ran out of it, now have enough for my oil changes for next 35000 miles. My system runs around 20 qts of oil per change, so add 18 oz of 9100 at every oil and filter change. I have around 111K on my 6.0 L, did rebuild it at 60K as I lifted the heads while pulling a heavy load.
Arrived in a timely manner
