Review: Noticeable Performance Boost & Smoother Diesel Operation 🚛🔥 - The Archoil AR6500 Diesel Treatment is hands down one of the best diesel additives I’ve used. After adding it, I noticed smoother engine operation, quieter idle, and improved throttle response almost immediately ⚙️✨. The fact that the two-pack treats up to 800 gallons makes it a great value, especially for regular diesel use. It gives peace of mind knowing it helps with injector cleanliness, fuel system protection, and overall efficiency 🛢️💪. Easy to use, high quality, and delivers real results—this is now a staple for my diesel maintenance routine! 👍🚀
Review: Legit works! Boosted mpg, range, and power - I suspect my Audi 3.0 TDI had a clogged cat some 5 years after a DPF delete back in 2019. MPG was down and it felt like it was also down on power. Sometimes the "Italian Tune-up" (high rev driving) would briefly help by blowing a lot of crap out the back, but it would go back to reduced after a day or two. I had been using the Hotshots Every Day in each fill-up, which may have slowed this issue down but it still happened. I also tried Opti-Lube XPD for a few months. Not much, if any, improvement. I do suspect they helped improve cetane values, but idk what else. If I had a good run, I was getting ~560 miles per tank. After some YouTube videos, I decided to try Archoil. I didn't notice anything for a couple fill-ups, but after about 1-1.5 months, I started to notice some slight improvements in mileage to/from work and some other trips. It was getting hard to hit 30 mpg on the way to work, whereas I started hitting 31-32, even with significant traffic. After 2 months, there has been a definite improvement. I'm currently seeing 33+ mpg on the way to work (same conditions as before) and reaching closer to the 38 mpg EPA advertised on my way home. I've also hit 42 mpg coming home from a friends' house, whereas before it was struggling to hit 39. Power feels like it has returned to expected levels compared to the previous treatments. My range is now reporting >600 miles per tank, even dealing with some stop and go traffic. For the results, price, and ease of applying into the tank, I highly recommend using it and I intend to continue using this from hereon out.

## Features

- EASY USE AT EVERY FILL-UP (2-Pack Value): Add directly to the fuel tank at each fill-up. Includes two 40 oz bottles – each treats up to 400 gallons (800 gallons total)
- FOR ALL DIESEL ENGINES: Suitable for use in all diesel vehicles and equipment - light-duty, heavy-duty, pickup, SUV, van, RV, etc. (including modern HPCR systems)
- IMPROVES LUBRICITY (ASTM D6079): Tested to improve lubricity by 43% to help protect fuel system components, including wear-sensitive parts like the CP4 pump
- BOOSTS CETANE UP TO +8: Raises cetane up to 8 points for faster ignition, smoother combustion, and improved drivability; many engines run best around 48–50 while pump diesel is often 40–45
- CLEANS INJECTORS: AR6500's detergent package removes injector deposits and restores spray patterns for improved atomization, supporting better performance and fuel economy
- SUPPORTS DPF & REDUCES REGENS: Targets deposit formation to help keep the DPF clean and reduce regeneration frequency – restores performance, fuel economy, and extends DPF lifespan
- KEEPS TURBO CLEAN: Helps reduce fuel soot and deposit formation that impacts turbo response, restoring boost and smoother acceleration
