Enjoy 6–10% better fuel economy with the Archoil Diesel Fuel System Kit.
The ultimate two-step solution for all diesel owners.
STEP 1
Deep Clean Your Fuel System with AR6400-D
- Rapidly removes carbon deposits from injectors (including IDIDs) and restores turbo and DPF function.
- Corrects injector spray patterns for improved power, response and MPG.
- Single use, one-tank treatment
Step 2
Upgrade Your Diesel with AR6500
- With your fuel system and post-combustion components now clean, AR6500’s detergent package keeps injectors deposit-free for maximum power, performance, and MPG.
- AR6500 boosts cetane by up to 8 points, raising standard U.S. diesel (CN 40–45) to the range modern engines require (CN 48-55) for improved MPG, reduced soot, and fewer DPF regens.
- Use at every fill-up. 1 oz of AR6500 treats 10 gallons of diesel.
WHAT YOU'LL NOTICE
- More miles per tank (6–10% fuel economy improvement is typical)
- Stronger throttle response and less turbo lag
- Longer intervals between active DPF regenerations
- Quieter, smoother-running engine operation
Archoil is the real deal.

Improved fuel economy, smoother running engine... We're now believers in Archoil.
I'm up 1.1 MPG and my customers are saying they're going a longer distance between DPF regens

The Diesel Fuel System Kit restores and enhances all aspects of diesel performance – including lubricity.
Independent ASTM testing shows AR6500 reduces wear by 43%, protecting high-pressure pumps (including the CP4) and injectors from catastrophic failure.
