"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."
Seems to work excellent. First time user
You use less of this than any other product on the market and it works better. Smoother running, better starting. Hard to comment on mpg because I'm a little heavy on the foot, but I do notice better response and a smoother engine. I use it in every tank. One bottle is good to get you through and oil change interval
It works in car, diesel truck, lawn mower, weed eater, golf cart
I’ve been using AR6200 since I bought my 2005 Ford F-350 2 years ago. My truck developed a injection stiction issue & Bill Hewitt from Powerstrokehelp.com recommended Archoil. My issue resolved in one tank of fuel! Since then I run the AR9100 oil at every change & the AR6400 fuel cleaner at every fuel filter change. The products perform extremely well and my engine runs like a beast! I do the oil analysis & have been able to extend the change interval. I’m a loyal fan of their products! Ordering is simple & delivery fast!
