Liqui Moly Diesel Pro Line is an absolute winner. Diesel EGR and air intakes and lines get dirty, and this reduces power, mileage, smoothness and everything else. You must clean your car regularly after every 20000 kms. I used this Pro Line cleaner and ended up buying 2 more of them. Engine became very bold and super torquey. You can use it in any Diesel car of any make, or even in DG or Tractor or other diesel consuming engines. Results will be immediate.
You can buy it from any store, you can try links of Amazon or can purchase from us. Links are below. Due to its high demand, it is often out of stock, but do let us know, we will help you in arranging one for you.
