How to choose

Six products here look interchangeable and are not. Five of them clean; the octane booster does not clean at all. Fuel injector cleaner — Cleans the injectors and nothing else. The routine, cheapest choice, and enough when the car has simply lost its edge. Complete / all-in-one fuel system cleaner — Injectors plus intake valves and ports, piston tops and the combustion chamber. The one to use for hesitation, rough idle or fuel economy that has slipped. Multi-system tune-up — Goes into the tank, the engine oil and the intake. For a car that has not been treated in years, or before a test. Octane booster — Raises the fuel's rating. It is not a cleaner — use it for knocking and pinking under load, or on poor-grade fuel. Carb, choke and throttle body cleaner — An aerosol sprayed straight at the part with the engine open. Never poured into the tank. DPF, turbo, EGR and catalytic cleaner — Diesel after-treatment. For a clogging filter, a smoking diesel or a failed emissions test.

Where it is the wrong choice

An octane booster will not clean an injector, and an injector cleaner will not stop pinking. They solve opposite problems and are the two most often bought the wrong way round.
