ArchoilAR6900-P Max Advanced Petrol Fuel Additive Concentrate, Treats 500L of Fuel, Petrol Injector Cleaner, GPF Turbo EGR Valve Cleaner, Super Unleaded Convertor, Octane Booster (500ml)

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'm very impressed with this product. I've used many others, over a few decades and this one is the best I've had. My petrol cars are high mileage and 20 years old. I ran this through both cars and about half a tank in, I could feel, sense the subtle differences in improvements, in each car. Felt livelier, ran and sounded better. Bearing in mind it'll get better, as I use it more.The litre bottle of additive will last me a little while.I put plain cheap unleaded fuel in and with the additive added, I don't have to worry about the grade or less detergents.I'm very happy with this product and it really does work.Great value.

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

Added to the fuel and have noticed an improvement in mpg ,using as a maintenance to the fuel system as well,happy with the product.

Ben using this for a few years. Certainly makes the engine run more smoothly

Better than expected will keep buying it for the future

Perfect

Seems to give fet a few more MPG. Or is it the placebo effect. Shows more MPG by 2 or 3 miles and you get some much forehead money.
