Review: Essential for My Tuning Business – Keeps Diesel Engines Running Smooth - I’ve been using the STP Ultra 5 in 1 Diesel Fuel System Cleaner in my car tuning and workshop business for a while now, and it’s been fantastic. I use it on everything from standard diesel vehicles to high-performance tuning projects, and it consistently delivers excellent results. This cleaner tackles multiple issues at once — it cleans injectors, removes carbon deposits, prevents corrosion, and improves overall fuel efficiency. I’ve noticed smoother running engines, reduced smoke, and more responsive performance after use. It’s also incredibly easy to use and works with every diesel vehicle I’ve tested. Compared to other fuel additives I’ve tried, this one really stands out for its reliability and effectiveness. It’s a small investment that pays off in better engine performance, longevity, and fewer maintenance issues. For any professional working with diesel vehicles — whether in tuning, repairs, or general maintenance — the STP Ultra 5 in 1 Diesel Fuel System Cleaner is an absolute
Review: Surprisingly Effective – Brought My Car Back to Life! - I was skeptical at first, but this STP DPF Cleaner really impressed me. I used it on my 2016 BMW 320d which was starting to feel sluggish and occasionally throwing up a DPF warning light. After adding the full 200ml bottle to a full tank and going for a steady motorway drive, I noticed a clear difference after just one treatment. The engine feels smoother, acceleration has noticeably improved, and the DPF warning hasn’t come back since. It genuinely feels like the car is breathing easier now. I also appreciate that it’s made in the UK – gives me confidence in the quality. If your diesel car is showing early signs of DPF clogging or just isn’t performing like it used to, this is a simple and affordable solution before jumping into expensive garage visits. I’ll definitely be using this regularly as part of my maintenance routine. Highly recommend!

## 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.
