"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 always use this in my fuel each fill up. Works well
Very pleased , good stuff . My 1996 Silverado runs smoother .
I have used this product on a BUELL 500 single , bought used due to carbon build up in the combustion chamber
The spark was moved back 5 degrees for a few thousand miles then after the carbon burned off it was
Returned to normal advance setting. In years past all that was needed was to do 100 mile cannonball run
This doesn't work today because of the poor gas with the heavy aromatic compounds added.
I learned about AR6200 from a youtube video by Jay Leno, he uses it in all his cars to counter act the ethanol. Never had anything go south so I'm a believer.
