Review: Cleaned - Cleaned fuel system
Review: I might buy it again - 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.

## Questions & Answers

**Q: Hi, I know this has been asked already but is this safe to use on a motorbike?**
A: Hi yes. I use it on my old Norton. Works wonders but don't use the whole bottle

**Q: Will this restore old petroleum in my boat fuel tank**
A: Don't know about boat, but my husband said it was great in the car. Hope this helps a bit

**Q: Can I use both the 5 in 1 cleaner and injection cleaner in one full tank?**
A: You could but I wouldn't.  Both products have properties that help clean various parts from the Fuel Tank to the Combustion chamber. In fact the description of both products show 1-2 identical properties. Just use one and then the other after doing a the guide line of 3-4 thousand miles.

**Q: Can this go in a 4 stroke petrol moped?**
A: Yes no problem

### ⭐⭐⭐⭐⭐ Perfect. Stopped my car from shaking at start-up
*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.
