## Questions & Answers

**Q: Will it work with car being stationery**
A: Yes but i wouldn't burn a whole tank of fuel stationary. If you mean just while in traffic, yes as long as the engine is running.

**Q: when do you put it in?empty tank or anytime**
A: It states to wait until tank is nearly empty then add immediately (ie at Petrol station and without starting the engine) before filling with approx 40-80 litres of diesel per full 430ml of additive. I used half in 40 litres

**Q: Is it recommended for EGR cleaning ?**
A: Not sure if it cleans EGR 
But works incredibly great for turbo,DPF,and cat , best on market does what it says

**Q: How often can it be used as i do 600 mile a week and first one made a difference**
A: It takes probably around 10 to 20 thousand miles for the carbon to build up in places like the EGR (exhaust gas recirculation valve ) if yours has never had this treatment you will have possibly noticed a difference before and after? Hope that’s a help

Seems to work well

### ⭐⭐⭐⭐ Does actually work and improve engine feel and fuel economy
*by I***A on 6 May 2017*

Must admit I was sceptical that any fuel additive did anything other than waste money. However, my old diesel engine was starting to idle heavily so I decided to give an additive a try. Research on the web suggested Archoil was one of the better ones. This size of bottle is sufficient for one tank of fuel. Run your tank low and take the Archoil bottle with you to the station. Break the foil seal on the bottle and tip the bottle into the fuel tank. The long thin neck on the bottle means it goes down the fuel inlet with no splashing of the contents. Then fill up with Diesel, this will give the correct concentration of additive for a typical family sized car. I used to get around 600 miles per tank, used plus remaining miles always hovered around a total of 600 figure, now it is around 680 miles. But the biggest improvement is in engine idling, the engine is much quieter now. I do not experience any improvement in acceleration so I am still sceptical about the claims for improved performance but miles per gallon and a smoother idling are definitely improved for my 2 litre TDI engine.
