Comma Petrol Magic – 400ml (PEM400M)

Description

Genuine Comma · Part no. PEM400M

Safety: Danger. May be fatal if swallowed and enters airways. Read the label before use.

Comma Petrol Magic is a 400ml fuel additive for petrol engines, poured into the tank to help an engine that has started to stall, hesitate or feel flat when you accelerate. Comma says it brings back lost power and acceleration, improves fuel economy and lowers exhaust emissions, which makes it a sensible first step on an older or neglected petrol car.

Good to know

• Can I use it in a diesel? No, it is a petrol additive; diesel cars need a diesel-specific treatment, so check which fuel your car takes before pouring.
• How do I add it? Follow the dose and directions printed on the bottle; most fuel additives are poured in just before you fill up, so the incoming fuel mixes them through.
• What if the car still stalls afterwards? An additive can clear deposits but won't repair a failed sensor, coil or injector; if the problem stays, the car needs a proper fault check.

Which one?

For a deeper clean of a petrol system, the STP Complete Petrol Fuel System Cleaner – 400ml (50400EN) is the stronger treatment; for regular protection between services, the NAPA Petrol System Protector 300ML (NAD1012) suits direct-injection petrol engines. Neither is on our site yet.
