Ultimate Diesel Kit

stock 7.3 ford 2002'

My truck has been running over a high Sierra Nevada mountain pass 3 to 4 days per week summer & winter in snow or shine. I really like the way your products are working. I'm the original owner & I will never sell this F-350 4x4. your products is a good investment. truck's exhaust is running cleaner than my friend's new 2025' diesel pickup, that has not tried your products, yet!

Game changer

I have a 27 year-old 73 diesel excursion. I put this formula in my truck and the responsiveness is just brought it back to life so much. I’d recommend this to anybody.

False claims

I decided to give Archoil a fair shot in my 2014 Ford F-350 6.7 Power Stroke after seeing all the claims about improved fuel economy, smoother operation, and overall performance. I ran the product exactly as directed for about a month. Unfortunately, I haven’t seen any measurable improvement in fuel mileage. My truck is well-maintained, and my MPG has remained essentially unchanged. I also didn’t notice any significant difference in power, throttle response, or engine smoothness. I’m not saying it won’t work for everyone, but based on my experience, it did not deliver the fuel economy gains that were advertised. For the price, I expected to see some noticeable results. The product didn’t cause any problems, but I can’t say I’d buy it again based on the results I’ve seen so far. Pros: Easy to use, no negative effects. Cons: No noticeable fuel mileage improvement, expensive for the results. Just one diesel owner’s honest experience. Your results may vary.
