  • Worked wonders on my high mileage 2004 Hyundai Santa Fe
The media could not be loaded. I prefer products that are easy to use without a lot of complicated steps. A friend recommended this, saying it could help with oil sludge and leaks, so I figured I’d give it a try. It’s supposed to work differently from regular chemical cleaners, using a process that helps keep the oil flowing better and reduce engine wear over time. I tested it on my 2004 Santa Fe, which has 273,000 miles and a small but persistent oil leak. I changed the oil, added the product, and took the car for a short drive nothing special, just a quick grocery run. After a few days, I noticed the leak had slowed down significantly. I won’t say it’s a miracle fix—if you have a major leak or engine issues, you’ll still need real repairs. But for an older, high-mileage car, it’s a low-cost option that seems to help. Definitely worth trying if you’re looking to keep your engine running longer without spending a fortune. I also used this on my son’s 2018 Honda Civic. He mentioned that his car glides more smoothly during start and stop, without needing to press the accelerator or brake as much. He can really feel the lubrication working in the engine. Overall happy with the money spent. ... show more

  • Not stopping oil drip on my car
I have a 1987 Honda CRX with 56,000 original miles that has a small quarter size oil drip. I used two bottles of engine wizard engine treatment with no success. Maybe it works on some cars but not my car.

  • works immediately!
Got it yesterday! Packaging looks nice and it was super easy to use. Poured it in, let the car idle for like 10 mins, and wow... my old 15 y/o Toyota Sienta definitely runs smoother now. Way less shaky. Driving actually feels better now lol. Gonna toss one in every oil change from now on. Lowkey addicted to this stuff 😂 ... show more

  • Great product, worth the money
I‘ve been using this engine oil additive for about a month now, and I’m seriously impressed. It works perfectly alongside engine oil to help neutralize carbon deposits in the oil tank, and I can really feel the difference. My engine runs so much smoother and quieter than before, and I‘ve even noticed a slight bump in fuel efficiency. The best part is that it was easy to use, and the results kicked in pretty quickly. It exceeded my expectations. ... show more

Fast shipping, and the seller was very quick to respond and provided helpful usage advice. After using this product in my car, I noticed that fuel consumption has significantly improved, and the engine noise has reduced a lot. I will definitely continue to purchase this product!
