Archoil AR6900-P Max Advanced Petrol Fuel Additive Concentrate, Treats 500L of Fuel, Petrol Injector Cleaner, GPF Turbo EGR Valve Cleaner, Super Unleaded Convertor, Octane Booster (2 x 250ml)

A value for money product that will treat up to a 1000 Ltrs of fuelSmells a little but not unpleasant

This stuff seems to work well. My cars engine seems slightly smoother especially at idle and a tad more responsive when on the move.

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.

Treated my bargain buy Peugeot with some of this petrol treatment. Prior to use idle was lumpy and acceleration sluggish at times. Since using this in supermarket fuel the difference is really noticeable. Smooth idle, improved fuel economy and better acceleration. Well worth the money

This is a really good value way of making sure your engine stays optimised.I've bought this for a couple of cars now including my daughter's so it must be good.It's restored the power and at this price and small amount needed per dose it will last a long time.

I use redex but I thought I would it a try over 4 classic cars on super unleaded jag 4.2 xk8 aston db7 3.2 s/ch RR 6.75 silver spur 3 . All cars are in weekly us arnarge R 6..76 twin turbo so a good test (So far looking good )

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