If your old diesel car has an ITV appointment pending, they have a product on Amazon that is rapidly increasing sales. With hundreds of positive reviews, this pre-ITV package of the STP, a miracle that can help you complete the review. It also helps reduce consumption, according to the manufacturer.

We are talking about a treatment for diesel engines from the American company. STPpromises to reduce emissions, save fuel and restore engine performance.

It is a suitable package to reduce emissions before checks made in ITV testing. Applicable to all diesel engines, even direct injection. It’s also really simple to use: just add the additive to the fuel tank.

This product is a top seller on Amazon and among the many positive reviews we have some products similar to this one:

10 worked for me, they kicked me out of MOT due to smoke, gave 4.5. It didn’t even rev the engine, as I did a few times before adding the product. I put in the two boots that came in, spent a third of the tank at high RPM and came back. It gave me 0.0. Miraculously, I disinfect the air while driving, if it gives less. Zero point zero, pure oxygen, crazy. Now they have to pay me to drive this car through the center of Madrid. Highly recommended.

Or this other:

I don’t know as I haven’t tried the taste, but it works, it works. In My Ibiza the engine icon appeared on the dashboard and was removed after adding both. Maybe occasionally, but much less. What it fixes is the safe mode (EPC) issue in the car. Before hitting the highway, the car lost power and I had to turn it off and then back on. Now none of these. Although I have read reviews that it is a waste of money, I would definitely recommend it. In my case, nothing could be further from reality.
