actually seems to do something
I had some issues i think now were caused by using supermarket diesel. I tried a few other cleaners but this one seemed to actually make a difference. Now I recognize the smell when i fill up at Esso I think the difference is they add cleaner while supermarkets skimp on that so are cheaper. I'll just use Esso in future. I've added what was left to some diesel i've got in reserve for storage as its supposed to extend the life significantly.

No complaints
Bought a new high mileage suv. Wanted to ensure the system was clean. I also repaired the swirl flap but can't say I'm having any issues. In fact, the engine's pretty damn smooth.

Importado dos EUA e é ótimo.
Muito bom para carros antigos movidos a Diesel S-500. Limpa bem a linha do combustível e o recipiente já vem com as medidas a serem colocadas. Vale a pena investir.
