Best fuel additive I've used in 20 years
By: Michael I. | 2021 Toyota Camry | October 15, 2024
I've tried every fuel additive on the market over my 20 years of DIY car maintenance. ZP-500 is the only one where I actually felt the difference. My Camry went from 28.5 MPG to 32.1 MPG average—that's a 12.6% improvement. The engine also runs noticeably smoother, especially during cold starts. I'm now using this in all three of my family vehicles.
Skeptic turned believer
By: David R. | 2019 Ford F-150 | November 2, 2024
I normally don't write reviews, but this product deserves it. My F-150 was getting 16.8 MPG combined. After using ZP-500 for three tanks, I'm consistently getting 19.2 MPG. That's a 14% improvement. The truck also starts better in cold weather and has noticeably more power when towing my camper. Worth every penny.
Mechanic approved
By: Robert K. | ASE Certified Mechanic | October 28, 2024
As a professional mechanic, I'm very selective about products I recommend. ZP-500 is one of the few fuel additives that actually delivers on its promises. I've personally tested it on customer vehicles and seen consistent improvements in fuel economy and engine performance. The PEA detergent formula is professional-grade, unlike most retail additives. Highly recommended.
Saved my old Suburban
By: James P. | 2008 Chevrolet Suburban | September 19, 2024
My 2008 Suburban has 185,000 miles and was running rough. Mechanic said I needed injector cleaning at $600+. Decided to try ZP-500 first. After two tanks, the rough idle disappeared and the hesitation on acceleration is gone. MPG improved from 13.2 to 15.1. This product literally saved me hundreds of dollars in repairs. Can't recommend it enough for high-mileage vehicles.
