## Questions & Answers

**Q: Where does this go**
A: Hello Julie R,
   The STP diesel treatment goes in the fuel tank when you fill up. It should have the correct amount per tankful on the bottle. Be careful not to use too much as you don`t want to finish up with an over- concentration of treatment in the tank as this can damage non-metal components of the fuel system. Hope this helps. - Andrew

**Q: Can i put the diesel cleaner, dpf cleaner and injector cleaner in all at the same time?**
A: Hi. I wouldn’t as the 3 are very similar. 
Depending of the issue you have use the one design for 
Fill your car with premium diesel then add the one you really need. 
I usually leave the car overnight and go for a Motorway drive. About 10 mins will do. 
You can add the others on a later date.

**Q: Would this be more beneficial if used with a regular full tank of diesel or a premium full tank of diesel**
A: I’d only use premium diesel regardless what the car was.
Cheaper diesel are the reasons why engines become blocked hence these products being created.

I’d virtually empty the tank then put this in then premium then you’ll see the difference 

Hope this helps
Thomas

**Q: How much do you put in the fuel tank**
A: 200ml treats 50/60 litres of diesel...so half the pack will treat a typical 25 litre diesel refuel.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product
*by J***T on 2 July 2023*

My husband was recommended to use this now and then; he hasn’t looked back; he says that this has vastly helped with the performance of his van.

### ⭐⭐⭐⭐⭐ Costs a bit more but great value
*by A***N on 11 February 2024*

It may cost a bit more but it works the best out of all the brands.

### ⭐⭐⭐⭐ Recommended for use...
*by E***E on 2 March 2020*

This was recommended by my mechanic for my used vehicle along with “not using cheap fuel” as it leaves more impurities in the engine. Difficult to assess any results, positive or otherwise but I’d say there’s some improvement. Update... Although I can't fault the recommendation to use this product as any product that helps clean the engine can't be a bad thing but the smokey engine got worse putting a permanent Coil light on my dashboard. That was only when my mechanic was able to pinpoint the cause. Not necessarily blaming the mechanic as these faults can be difficult to locate unless it triggers a management light. Smokey engine has since been cleared and engine is running well. Maybe the product has help in the engine running better, I'm guessing it has.
