Did it work ?** A: I had an old Toyota with oil leaks. I used Slick50 for many years and it didn't effect the leaks at all. But it was a 20+ year old car. I don't think the stuff is made for repairing leaks, anyway, once they're there. **Q: This clogging agent to stop leaks, does it clog all holes indiscriminately? Even holes that it shouldn’t like honda vtec selniod?** A: I don't see a "clogging agent". It claims to "revitalize" seals to prevent leaks **Q: Will this work for 2013 dodge ram 1500 4.7 engine** A: It should work most any gasoline engine. Do not over fill the oil crank-case. Helps best for me for the cold winter mornings when start-ups are these noticed. This stuff does not fix anything, but it seems to help with engine cold starts. **Q: Can i use it for 0w oil?** A: "It is fully compatible with all conventional, semi-synthetic and full synthetic oil types" is the product claim ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as advertized. *by Z***R on 7 April 2021* The engine is quieter and I'm getting ~10% improvement in fuel consumtion in my +190,000KM milage car. ### ⭐⭐⭐⭐⭐ Excellent Choice *by M***E on 25 December 2020* Right choice, engine feels smoother and reduces lube loss from engine oil sump. ### ⭐⭐⭐⭐⭐ Good product *by C***G on 18 September 2022* It help to reduce vibration and noise and gain little performance back ## Frequently Bought Together - Slick 50 750002 Recharged High Mileage Engine Treatment, 15-Ounce - Slick 50 41806015 Recharged High Mileage Automatic Transmission and Engine Treatment, 15-Ounce , black - Slick 50 Original Classic Engine Treatment with Cerflon, Ceramic Protection Against Friction and Heat, 32 fl. oz, 1 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/253992954-slick-50-recharged-high-mileage-engine-treatment-444-ml-h8](https://www.desertcart.hr/products/253992954-slick-50-recharged-high-mileage-engine-treatment-444-ml-h8) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-18*
