"As a former mechanic I never believed in additives but this is my 3rd purchase of this product and used on 3 different vehicles with great results. On my BMW X5 it made the idle smooth and the MPG up by 2. On my LML increased the regeneration interval from 300 to 600 miles. On a friend's TDI took care of a hesitation it had."

"The engine noise became noticeably quieter after about 20 to 30 miles of driving. No smoke out of exhaust. Before any Archoil products this truck was lucky to get 14 MPG on the highway. I just drove back from New Mexico with a slight tailwind and AR6500... one leg I got 20 MPG!! This truck in 60,000 miles has NEVER gotten 20 MPG before!"

"I use it in all my diesel engines. Keeps them nice and clean inside.I was amazed when I pulled the valve covers. It was showroom clean - no sludge, no blowby residue, nothing. Could easily read the serial numbers on the injectors. As far as stiction goes, I don't have any with my Power Stroke and it runs smooth and fires right up."

Great Stuff

My experience on both gasoline and diesel (2016 MY MB Sprinter) is that the improved mileage (ca 1mpg+) helps pay for keeping injectors and engine in good condion as evidenced by smooth and reliable performance on high mileage vehicles.
