It's TRUE
I have always seen advertising claims for various products and 90% of which are false but not Archoil. I have used AR 6500 for a month now and I can honestly say that it works as advertised. My mileage went from 17mpg to 20 mpg highway running at 80 mph. Im glad that I signed up for automatic refills.

Use max treat rate
I have been using Archoil AR6500 for years. I was using the minimum treat rate. I increased to the maximum and my mileage has increased by about 15%.

Will continue to use.
I own a 2025 GMC 2500HD, and after doing extensive research on some of the common issues GMC trucks have experienced, I wanted to take preventative steps wherever possible. One concern I came across repeatedly was fuel contamination related to diesel fuel quality in the U.S.
After reviewing several diesel additives with generally positive feedback, I decided to try AR6500 Diesel Treatment because it consistently had a higher number of strong reviews compared to similar products.
Since using it, I’ve noticed a slight improvement in fuel mileage along with better throttle response. I’ve used this product since the very first tank of fuel in my truck, and I currently have 6,376 miles on it while only using approximately half a box of DEF.
Based on my experience so far, I’m pleased with the product and plan to continue using it.
