AR6900-P Max Advanced PETROL Fuel Additive Concentrate, Treats 500L of Fuel, Petrol Injector Cleaner, GPF Turbo EGR Valve Cleaner, Super Unleaded Convertor (500ml)

Excellent additive, cleans your injectors, helps your mpg, has a bit of a funky smell but you won’t notice it once you add it.

Excellent delivery time..... top marks to supplier and Royal Mail in Christmas week 👍👍 ..... a great product to help keep the fuel system clean.

Seems like good stuff but the bottle leaked all over my boot. Not good since it says it causes lung damage.

Works great om my audi really makes a difference

I was skeptical because I've used so many octane boosters/ fuel system cleaners and have had no results. But this stuff actually increased my cars mpg slightly and reduced throttle lag by quite abit. I would highly recommend.

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!

Makes a significant difference, better than Tesco 99 octane when used in regular feul in my opinion.

Not sure - only measured first treatment and waiting for results. Needs a little thought to use correctly but fingers crossed!
