Do you use the whole bottle in the tank.

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.

How often should you use this

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.

How much do I need for a 90 litre tank

I poured the whole bottle into my Disco 4 a week before my mot and it sailed through on its emissions test.

How often should you use this product?

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.
