In the BMW E46 engine, with over 250,000 km on its back, checking it through the computer (INPA) showed that the fuel injection in one cylinder had a significant difference from the other three. The check engine light did not come on and there was no apparent functional problem, so I didn't want to intervene. One day, I came across this product and thought I had nothing to lose by trying it.

It was some of the best money I've spent on the car. I put it in half a tank and after burning most of it, the sound of the engine had completely changed, while it was noticeably running smoother. The INPA now shows all four cylinders in perfect alignment. Additionally, fuel consumption has dropped by at least 1.5 liters/100 km according to the board computer. I didn't notice a significant difference in performance, but the engine is definitely running much better.

Today, three tanks after using the cleaner, the INPA still shows that all four cylinders are functioning equally. Therefore, the effect of the cleaner lasts.

It's definitely not a magic filter that solves all problems, but it is certainly effective in specific cases, especially in vehicles with high mileage.

I tried it with 100 octane gasoline and I was very disappointed.
And because we have a misunderstanding of what octane means (no, it doesn't have to do with extra energy) and why I wasted money on both without reason.

I removed the spark plugs and took a photo before and after the pistons, no difference! Neither did I see any difference in fuel consumption with the OBD2 scanner. Nor in the engine compression. The worst part is that as soon as I put it in and took it for a ride, it threw a P0300 Error (misfires). I thought I would be stranded. And I paid, meaning I was ripped off.

So I started investigating, you should also take the trouble to find out what chemicals it contains (take a look at the company's website to see if it says anything) and find references with some credibility, not jokes here (including myself).
Don't believe a word!
Before you put it in your engine, though, have you ever wondered if we all would like a "magic potion" to fix or improve our engine? Doesn't it sound like the elixir of immortality? Maybe it's too good to be true
