## Description

STP 65400EN Complete Diesel Fuel System Cleaner-Diesel 400ML

Review: Cleaned fuel system
Review: I normally use another product which is readily available at supermarket garages, but I thought I'd give this a go. 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.

- RESTORES ENGINE POWER – Improves throttle response and acceleration.

- REDUCES EMISSIONS – Helps minimize black smoke and harmful exhaust output.
- TREATS UP TO 50L – One bottle is enough for a full tank treatment.
- SAFE FOR ALL DIESEL ENGINES – Works with turbocharged and direct injection systems.
- EASY TO USE – Simply pour into fuel tank before refueling for best results.

### ⭐⭐⭐⭐⭐ Review
*by S***A on 7 April 2023*

My BMW (12 years old with 113k milage) started to shake when I’d start it up. 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.
