MANNOL Octane Plus Booster 450ml

Just had a stage 1 remap on my Infiniti. Whilst it was noticeable I wouldn't say it would blow your socks off as the car was quick anyhow. Its now pushing 400bhp and this stuff made an incredible difference. I was skeptical tbh as I have used this type of product in the past with minimal gains, if noticeable at all. I added on a near empty tank and then put 36 litres of 95 in, slightly less than the recommended mixture. Drove for a few miles and then stamped on the gas. Instant response and pulled much better than before. It was honestly noticeable not just the placebo effect. Probably goes hand in hand with the remap? I wouldn't use every tank as that would be expensive but as a play around it definatley works. The health warnings are a bit scary and to be adheard to I guess. Made sure I wore diesel gloves when adding. But overall if you drive a performance car I would say try it. I'm not in anyway linked to the manufacturer or supplier just a curious petrol head.

Did give the car improved performance. Bottle needs a redesign though for filler neck.

Seemed to work. Gave the boost to lower grade petrol making bike easier to start. Would say give it a try. Not surd about making it run any faster 😁

Well............. that does the job!!!!!!!I have a 2004 GSX600F, and normally only put super unleaded in it. For some strange reason, I decided to put standard unleaded in. My bike hated it!......... Poor power, lumpy under 3k revs, cutting out on tick over. Awful. So, before I went as far as to drain the tank and waste the fuel, I thought I'd give this a go. I put half the bottle in the tank, and INSTANTLY there was a remarkable difference. If I'm honest, I don't think my bike has ever run this well. I'll definitely be putting the remainder of the bottle in with super unleaded to see what a difference that makes!Amazing product. Highly recommended.

I own an Alfa Romeo gt 2.0 Jts petrol. I don’t live near a fuel station where I can buy decent 98octane fuel. My car has been pinking under acceleration. I thought I would try this product and it really has worked !! No more knocking and definitely a smoother power delivery 👍👍. Cost wise. It probably works out the same as filling up with V power petrol per tank. Very good product.

It works what more can you say

Brilliant product does exactly what it says on the bottle. Easy to use, once it’s mixed around and got into the system all i can say is unbelievable and highly recommend and I currently won’t use anything but mannol

If your car has pops and bangs this will make them significantly louder. I definitely noticed the boost in performance. Don’t get me wrong it’s not NOS but it’s definitely good. Ill be using this before my next dyno run so I’ll be buying more.
