Which one should you buy?

Buy the Liqui Moly Petrol Injection Cleaner if you drive a petrol car and want a cleaner rated for all petrol injection systems, 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 look at the Liqui Moly Diesel Clean and Boost, which Liqui Moly states suits all diesel engines with or without a particulate filter; check the card for stock first.
