Review: Life saver. - This was used to clean the level sender in the tank as it had stuck on the 1st notch even with a full tank. Put in the tank and next day problem solved. Saved me having to replace the sender unit.
Review: It actually works! Cleared injector on Mercedes C220 and Engine light went off. - We have a 2005 Mercedes 220d estate that’s done 150,000 miles. Generally the car is trouble free and we love it. Then last week the dreaded amber engine light came on on the dash. Off to John Haynes our local Mercedes specialist. £95 later it was diagnosed as a blocked or blocking injector on cylinder 3 - cost of a refurbished unit around £350! The fault had by then cleared so The light was switched off by the garage but illuminated the following morning on startup confirming the issue. Not wanting to pay more money out I researched various blogs and found this product. Felt it was Worth a try as it’s cheap and there’s no dismantling of engines etc. Popped in the whole lot when the car had just 1/4 tank of fuel left. Two mornings later the engine light went out and has stayed off ever since. Car drives again as normal. We have decided to purchase this every 3 months now just to ensure the fuel system remains problem free. Highly recommended.

## Questions & Answers

**Q: Do you use the whole bottle in the tank.**
A: Yes you do. Ideally you should use full bottle in quarter tank of fuel then fill tank to full, this then mixes to proper ratio. It is only needed every 5-10,000 miles or so apparently. Does it work? Who knows, but if you drive a car which clearly states “No Biodeisel” and ALL uk fuels contain at least 7% bio by law then anything to help clean the fuel system is worth trying in my view.

**Q: How often should you use this**
A: Techron website recommends to use every 3000 miles. Personally I use every 5000 or so and my car fuel system is considered to be good and clean at 80,000miles. Hope this helps.

**Q: How much do I need for a 90 litre tank**
A: I poured the whole bottle into my Disco 4 a week before my mot and it sailed through on its emissions test.

**Q: How often should you use this product?**
A: The product does does just what it says on the bottle.
I run a Jaguar XF 3:00ltr diesel, and using this product 
I get 49 to 53 M.P.G. on a run to Brighton, so buy and do 
what is written on the bottle.
