"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."
It worked real well up until someone stole my truck.
I have not had a chance to use the product yet !!!!!!!!!!!!!!!!!!!!!!
Excellent product as always guys !! Just when I thought you guys couldn't make an already excellent product (ar6200) better you never cease to amaze ! Using the ar6500 in my 06 ford f250 6.0 powerstroke I gained a little more than 1 mpg. And its even yet smoother and quieter than when using the 6200 religiously, on my second tank of it right now couldn't be more impressed ! Keep up the great products guys ! Will definetly keep buying and reccomending to everyone I know!
Excellent product works well
I am using it in my 79 Ford Tractor and it runs better than it ever did. Less smoke and fuel efficiency is great.
