It used to feel like it was going to take off but the shaking would only last for about 15 seconds or so. I thought it’d be an expensive fix but came across this and thought I’d give it a try. Filled up a full tank of Diesel and then poured the entire contents of this bottle in immediately after. I didn’t notice much difference whilst driving like some people say (I didn’t have any performance issues anyway). However, the shaking at start-up has finally stopped! It’s recommended to use this product every 4000 miles so I’ll definitely be doing that as it has certainly helped with the shaking issue. I’d recommend this.

It used to feel like it was going to take off but the shaking would only last for about 15 seconds or so. I thought it’d be an expensive fix but came across this and thought I’d give it a try.

Much more expensive but apparently it is meant to last much longer rather than using half a bottle of that other stuff each time I fill up. Overall I do think it did a good job but I don't think I would buy it again in a hurry. ## Frequently Bought Together - STP Diesel Complete Fuel System Cleaner 400 ml - STP Diesel Particulate Filter Cleaner 200 ml, Cleans and Protects Your Filter by Removing Soot in One Treatment, Restores Power and Acceleration, Mechanical Car Cleaning Products, Made in the UK - STP GST59200EN Diesel Injector Cleaner 200 ml,Packaging/label may vary --- ## 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.tn/products/670760970-65400en-complete-diesel-fuel-system-cleaner-diesel-400ml](https://www.desertcart.tn/products/670760970-65400en-complete-diesel-fuel-system-cleaner-diesel-400ml) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-01*
