Petrol Treatment & Additives


Rated 5 out of 5 by from Worked a treat! I found my car would judder a bit when first started and the engine seemed a bit loud. I thought I would give this a go. Within 25 miles I started the car and went to drive and no judder, also noticed it sounded quieter and also was more responsive, my cars 14 years old this worked a treat, great product!!!

Rated 1 out of 5 by from Avoid unless you like a misfiring engine I m a regular user of petrol additives. Some brand/kind will have more or less effect but I never had a bad experience… until now. As per indications, I poured the bottle of additive in a full tank of petrol (60 litres, BMW E91 320i) and drove about 1 mile to get home from the petrol station. No problem. Next morning: I start the car and notice the idle is a bit erratic for about 10-15 seconds. I went on my way and I could feel the car hesitating under acceleration but also at constant speed. I drove the car about 100km and it was clear the additive created the misfires… After syphoning about 30 liters of ‘contaminated’ petrol out of the fuel tank and filling it with ‘clean’ petrol, the misfiring improved but did not completely stop. I had to completely syphon the fuel tank… filled it again with ‘clean petrol’ and the car is back to running smoothly. Hopefully this hasn’t caused further damaged. So this amazing product cost me 20 quids, plus another 120 quids in contaminated petrol… I hope this

Rated 5 out of 5 by from Fuel efficiency I use this product every 10,000 miles or when my car feels a bit sluggish. It’s definitely beneficial to the health of the engine. My car is near the 90.000 mark & still going strong….. as if new.

Rated 4 out of 5 by from Feel the difference This product is cheap enough to use at least three times a year and notice quite a difference! When I first heard about it I was very sceptical, however upon using this product several times I can guarantee i can feel the difference in my engine after one use! My car drives better and the engine feels smoother both at low and high revs.
