Stp 18030 Super Concentrated Fuel Injector Cleaner 12Oz (354ml)

It didn't make any difference. Fuel economy is the same and didn't observe any difference in acceleration

nothing

I recently tried the STP Super Concentrated Fuel Injector Cleaner, and I was quite impressed with its performance. After using it, I observed a noticeable improvement in my vehicle's gas mileage, which suggests that it helped optimize the fuel system. The cleaning solution effectively removed carbon deposits and buildup in the injectors, resulting in smoother engine operation and better fuel efficiency. Overall, I would recommend this product to anyone looking to enhance their vehicle's performance and economy.

Definitely can feel the difference before and after putting this into the fuel tank. Everything seems to run smoother.

Outstanding performance improvement, I’ve just tested on 10 km distance on FIAT linea 8 yr old car, which is completing 30000 km. Immediately noticed, 1. PickUp/Acceleration is impressively increased 2. Mileage is increased by 20% earlier I was getting only a maximum of 13 kmpl on highway, now after adding I’ve got 17.4 which is outstanding improvement. I think this is something an achievement on Linea Petrol . 3. Update: after 725 km long run on highway my car mileage has gone up to 16.4 against the ARAI claimed 14.9 know. I’ve added half of this to my 45 liter tank, which is half full, then made full tank. But putting 50% of this really challenging as you don’t really know how much you are pouring as it’s supplied in opaque bottle. So what I did was I took a measuring jar, I’ve put 175ml (50%) of this then stored in some other container and closed immediately . To my shock in this small time 25ml is vaporised. Suggestion to brand to supply only required quantity as adding sufficient is very difficult.

I used this product for Skoda Laura automatic diesel car. The car was showing flashing glow plug light while driving. Service centre guy told to get entire fuel line checked and of course gave expensive estimate. Hence, I thought to check with other mechanic then decide. But after reviewing many online information for such issue, I decided to try this product first.. While on a long drive from Mumbai, I stopped the car on petrol pump, poured 75% of this solution into the fuel tank and then filled fuel tank to its full capacity. After driving the car for 30-45 mins, I noticed improvement in pickup. After around 100km, I stopped the car on a petrol pump and made tank full. When I turned on the engine, to my surprise the glow plug light went off. Also the engine was noticeably smoother and less noisy. 👍🏻 Now the car has done more than three thousand km running within any issue. The product is value is good and I recommend it. Thanks.

Worked with a lot of additives over the years. But this product's performance was obvious. The best part was during acceleration. No burnouts, no donuts (PS law enforcement lol) just a great boost. Not sure about mileage though. But happy with the overall results. Well worth the price. RLC
