"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 am using it in my 79 Ford Tractor and it runs better than it ever did. Less smoke and fuel efficiency is great.
Archoil is the best ever,I use it in both my 1997 7.3 and my 2001 7.3.16 mpg in city and they both purr like kittens.
Well worth it all around
Seems like it increased mpg a little. Driving a manual at a crowded tourist destination.
Used in my 7.3 brought it back to life great product never ran better thanks !!!
Great product gained 2 mpg better on fuel mileage and thinking long term hoping no repairs in the long run😎
