Which one should you buy?

Buy the Liqui Moly DI Jectron if you drive a modern petrol direct injection car, the Nulon Pro-Strength Petrol Extreme Clean if you want a local bottle you can replace anywhere, and the Nulon PIC if you just want a cheap pre road trip clean. Diesel owners should go straight to the Nulon Pro-Strength Diesel, which Nulon states is safe for all DPF systems.
