## Questions & Answers

**Q: Do you add this to the fuel tank or into the lambda sensor hole?**
A: It goes in the lambda sensor, this is only the rinse agent you need to buy the cleaner and the dispenser for it which is expensive, buy  the DPF cleaner fuel additive much cheaper and works a treat it's what I buy.

Worked great for Me. It’s for advanced diy and requires a pump to spray inside the dpf. Very pleased. Will probably repeat process this year.

### ⭐ Not an additive
*by P***O on 8 May 2019*

I assumed this was a liquid additive. I added it to my fuel tank. There were no description in the listing so I made and assumptions, there also were no instructions on the bottle. My car has been running terrible and I have had engine lights coming on hopefully I can keep topping up my fuel tank and dilute it down enough.
