Had I not thought it one can clearly see

I drive a direct injection of not yet being old but now after almost 90tkm idle fluctuated slightly with the speed, easily and hardly noticing but annoys me something.
Normally, I do nothing of such a "miracle" products are as simple to use and a lot of promise but I must say I am very pleasantly surprised.

Given a can in the fresh fully fueled with Super Plus 70 liter tank. Already after a few kilometers I realized at the traffic lights he was quite calm without the nervous twitch and slight fluctuations. The passage has not become noticeably better, but I use my performance anyway not often made. Me is much more important that it runs clean.

I'll give it back inside after a few thousand kilometers, at 9.50, the box can be the vehicle already treat times

Vehicle is an A4 Avant 2.0 TFSI
