Liqui Moly Diesel Purge is an absolute winner. Diesel injectors and lines get dirty, and dirty injection reduces power, mileage, smoothness and everything else. You must purge your car regularly after every 20000 kms. You can use it in 2 modes - Concentrated (when very dirty) Or Diluted (routine maintenance). I have shown ways to do both of them. 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.
