"You can add Diesel Tech magazine to the long list of testimonials as we're now believers in Archoil too.
"Improved fuel economy, smoother running engine and no issues with cold starts."
I ain't had a problem yet, add it every fuel stop
Top MPG in diesel and gasoline.
This is replacement for my last bottle which is running low. I don't want to be without this stuff. I bought my Ford 6.0L truck used with 164000 miles. Had to replace the EGR valve soon after. Now it has over 184000. Once I found this and started using it, the truck starts easier and runs smoother and no EGR issues so far... I also use the oil additive. I am a little confused about the new packaging and dosing levels. It feels like it has gotten more expensive. Still, it is worth it.
Very happy with the 2 supplements I ordered. I put them in our high mileage 7.3 Ford delivery trucks and also my 2 personal use Toyota's. I plan to recommend this with my friend Vincent who is a field engineer to the N.Y.C. M.T.A. for the Bus manufacturer New Flyer whom manufacturers all the buses for New York city. Thanks again.
I swear by Archoil and their products!! Can definitely tell a huge difference in power and performance when i forget to add this stuff to the fuel tank! I've also noticed a pretty big jump in fuel mileage. Used to get about 14.5 on long road trips, am now up to between 17 and 17.5!
