"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"
I've used Arch oil since 2012 on my 2010 chevy colorado and my 1979 chevy luv truck.My colorado has 141K miles and still going strong.At every oil change, I change it at every 6K miles.I use Mobile-1 high mileage,10W40 syntec.AR9100 keeps my engine clean.I use a little bit more than recommended.I also use AR6400-G and AR6200 to keep fuel system clean.I'am very satisfied and continue using Arch Oil products.
I was skeptical as usual having been mostly disappointed over the years by almost every additive available until now. After adding this to my 2006 duramax work van I noticed a much smoother operating engine and all.my subsequent morning starts are instantaneous I will be using in all my vehicles from now on.. Thanks for actually providing what you say you provide!!
2012 Ford Fusion 2.5 4 cylinder is a great engine, but the lifters are a bit noisy even using full synthetic oil. Put this in and I can now hear the injectors pulsing over the lifters now. Will definitely keep using this product after hearing the great reviews from the diesel community and with my own great results. This product is the real deal.
Have used this product for years with excellent results. Smooths out engine idle, adds power and reduces wear especially on cold starts and when hauling. It's science, not beliefs.
It help quite the lifters in my Chevy Tahoe.
