"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'm a diesel guy. This stuff really works.
I use it in every tank of fuel in a F250 Super Duty. I have not had a bit of trouble with the engine at all.
I first started using AR6500 after my son and I rebuilt a Ford 350 6.0. My son had ran across the feedback for the AR6500 and because of the great reviews, we wanted to give it a shot. The results in our 6.0 were FANTASTIC. You could hear the difference in the engine immediately. There was no delay. Having to check the egr regularly, we began seeing next to no build up on the egr. The engine sounded better, accelerated better. You could feel the difference when you drove it compared to before its use. Great product. I make sure I have enough for every oil change, every tank of diesel and every 3-5000 miles. We really use our 6.0 hauling, working, and towing. I can't say enough good about it. Shoot we have even added the fuel addictive to our riding lawn mowers and push mowers, which are gas, and they all run waaay better. If you haven't tried this product for your diesel, you have to buy you some. It might seem costly but the improvement on the engine is dramatic which will give you many many more miles out of your vehicle.
Awesome product! Mileage is up and regeneration happens about every 375-425 miles. Once in a while around 300 miles but not often. Very happy!
After 3 months after I brought my 2005 F-350 6.0LCC SRW I noticed hard cold starts & a stiction issue with my injectors. As a first time diesel & 6.0L owner, I did my research and Archoil’s products came up as the go to problem solver. I bought the AR9100, AR6500 & AR6400-D. Changed my oil, fuel filters, put in fresh full synthetic oil and the Archoil products. After warm up to operating temperature, my truck ran smoother & quieter! Every cold start afterwards was smooth & easy.
4 years later, I still add Archoil’s products at every interval! I do oil analysis & have been able to extend the interval each time! Archoil has a customer for life in me.
