Hydra PIC-24 Petrol Injector Cleaner and Carb Cleaner Additive, 2x500ml Treats 1000 litres, With Petrol Cleaner you get more Petrol Power with Octane Booster Removes Deposits Improves Combustion

I've left it a while to leave a review as I wanted to give it a chance to work.I ran the car as low as I dared on fuel before using the product and filling with new petrol.I've done around 200 miles and I can definitely feel a noticable difference to the running.The car idles more smoothly. Drives a lot more eager and (this may be just me) actually quieter.

I was buying their additives for my 2.0TDI A3 and got the extra grunt and smoother tick over, so when I switched to a 1.4TFSI, I thought I would buy this, in case the previous owner had only used cheap petrol and never cleaned the jets, or anything, in it 38K miles. I definitely feel a difference now that I'm halfway down my 4th tank full.Bought the car as I wanted the A3 saloon. I thought, 'Oh, this clutch and picking away, in a different car, is going to take some getting used to' but now that I have gone through as much of this stuff, in my tank, that I've stated above, I don't think it was a 'getting used to a new car and clutch' problem. I think it was a 'power delivery/ combustion efficiency' problem that was making it more difficult for me to control the clutch and pick away because, now, there is no such problem, at all.I haven't measured results for power or fuel consumption but there is enough testimony, here, to feel confident that I am, probably, reaping those benefits on top of the smooth running and tick over and slight, but significant, power boost that I feel.I'm a very experienced car driver, with over 30 years under my belt and 8 years of that, driving meal deliveries over a pretty wide catchment area. So I think I have good, what Jackie Stewart once said all good drivers should possess: 'mechanical sympathy'. So the clutch balance problem, having a bit of difficulty balancing it and only being able to pick away very slowly, was perplexing and frustrating, for me. I now think it was because the jets were coked up and dirty. They were probably spitting big bogs of fuel into the engine, just like the before and after diagrams show, giving inefficient and unpredictable power during that critical time, making it harder to control and more ready to stall and 'die'; which happened to me a couple of times.It was very annoying because my previous car felt like it was an extension of me and I wasn't 'feeling' this new car. I was having sellers regret and would rather have had my old car and my money back, if I could.Anyway, now, there is not a problem and it doesn't feel like I am doing anything much different with the pedals, than what I was doing when I first got the car.It feels much more like 'man and machine in perfect harmony', now and I can finally enjoy my new monsoon grey Audi A3 Sport saloon.It's been getting better and better, by the tankful and I think that's it now running, pretty much, as it should. Acceleration and throttle response, much improved.Not a lot of people know about this stuff and many might be sceptical but I am a firm believer in Hydra products now.Oh and 'pound for pound', adding this to a tank at the pump is only going to work out at about an extra £1.15, or something (or whatever 1/20th of the price is that you bought a litre bottle of this for, anyway), to bring your fuel quality up to, or beyond, the quality of premium unleaded. That's got to be much cheaper than what the price difference would be if you bought a whole tank of that stuff, at the pump.I'll be buying more, when it runs out, so I can keep adding a 50ml 'maintenance dose' to every 50 litre tankful, from now on. To keep my car running a treat.I've been telling people that 'I've got my car running better than when I got it' but most of the credit for that should go to Hydra (I'm sure there's a Marvel comics related joke in there, somewhere, but I ain't going down THAT road, ha).

Used this product on all my cars on a monthly basis. The Kia now has 160k on clock and still going strong and sure this helps.

Does exactly as advertised, better mileage and performance.

Fuel economy and engine idle smoothness both improved.

It was recommended by a colleague and really worked.

This product is amazing, used this in my car, the MPG has improved greatly, the car is running smoother and quieter. Would recommend

Does what it claims to. Smoother idle, better mpg, easier cold starts. Totally bosses the competition price wise as well. I will be ordering more.
