Archoil AR6900-P Max Advanced PETROL Fuel Additive Concentrate, 1L Treats 1,000L of Fuel, Petrol Injector Cleaner, GPF Turbo EGR Valve Cleaner, Super Unleaded Convertor (1Litre)

So far so good, noticeable improvement in engine performance and fuel efficiency.

Brilliant stuff. My S3 loves this. I’m now saving almost £20 per tank by switching to regular Shell Fuel Save vs V Power, and adding 50ml of this per tank.Previously, if put regular in, I had less power and a slightly noisier engine, solved by using V Power.Add this with regular fuel and there is no difference vs V Power, aside from saving a considerable amount of cash. Pretty much pays for itself after one fill for me, but I will get around 20 tanks from one bottle.Well worth it!

Cheap petrol/ diesel needs additive and this works perfectly - mpg increase 👍Warning... smells horrid!

Great product good price I bought it cause I’ve just had to replace my fuel injectors so using it as a preventative measure

Hi it certainly improves my L 200 it run smoother and being a direct injection it keeps it from stalling on take off the running has improved greatly will be buying again

Excellent cleaning properties to keep your fuel system and injectors in tip top condition, I used the solution neat to clean some stuck injectors from a BMW v10 engine and it brought them back to life and restored the spray pattern after 6 hours with the tips bathed in neat solution, I tested before and after with awesome results saving me a few hundred £££ on reconditioned injectors. I now add 50ml to every second full tank and after 600 miles I am still noticing improvements in performance. Excellent product

I kept getting the engine management light on my car after using my 'obd2' scanner (£30 off Amazon also) it listed the emmisions and or the DPF filter as faults so I bought this item it takes about 250 miles to work and I doubled the suggested dose

Excellent product , you notice the difference in your performance and mileage straight away
