The engine was getting sluggish and lacked any pickup power. After I started using the STP Fuel Cleaning System, I get a really good power boost and can feel the difference immediately after adding the STP. It also cleans the fuel injection that has never been cleaned or replaced. I add it with every fill up. I recommend it to anyone with an older model car that lacks the power it used to have. ## Frequently Bought Together - STP Complete Fuel System Cleaner, Fuel Cleaner Deep Cleans Entire Fuel System, 5.25 Oz, Multicoloured, 1 Count (Pack of 1) - STP Octane Booster for Gasoline Fuel Additive, 5.25 oz, Fuel Additive That Raises Octane Levels and Cleans the Fuel Intake System to Restore Lost Power and Acceleration, Help Improve MPG - STP Ultra 5 In 1 Fuel System Cleaner and Stabilizer, Deep Cleans Fuel System and Fights Engine Friction, 12 FlOz --- ## 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.it/products/323267496-stp-78568-complete-fuel-system-cleaner-5-25-fl-oz](https://www.desertcart.it/products/323267496-stp-78568-complete-fuel-system-cleaner-5-25-fl-oz) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-05*
