FAQs
Can I use Valvemaster Plus in a modern car?
Valvemaster Plus is designed for older engines requiring lead replacement. It is generally not recommended for modern cars with complex catalytic converters.
How much should I add per tank?
The recommended dosage is 1ml of Valvemaster Plus for every 1 litre of fuel added to your tank.
Does it clean fuel injectors?
Yes, the formula contains cleaning agents that help prevent the buildup of deposits on fuel injectors and fuel system components.
Is it safe for fuel lines and seals?
Yes, Valvemaster Plus is formulated to be compatible with standard fuel system components used in classic and older vehicles.
What happens if I use too much?
While a slight overdose is typically not harmful, it is always best to adhere to the 1ml to 1 litre ratio for maximum economy and efficiency.
Troubleshooting
Additive is difficult to pour accurately
Use a small graduated measuring cylinder or the cap markings if provided to ensure you do not over-treat the fuel.
Engine still feels rough after use
If performance does not improve after two or three full tanks, ensure there are no mechanical faults or ignition issues present, as the additive is for chemical maintenance and not a repair for broken parts.

Setup, Compatibility & Care
To use Valvemaster Plus, simply unscrew the cap and measure the required amount based on the volume of fuel you are adding to your tank. The standard ratio is 1ml of additive per 1 litre of fuel.
- Compatibility: Suitable for most vintage and classic engines. It is not designed for modern high-emission engines equipped with sensitive three-way catalytic converters.
- Storage: Keep the bottle tightly sealed in a cool, dry place, away from direct sunlight and out of reach of children or pets.
- Application: Always pour the additive into the fuel tank immediately before filling up with petrol. This allows the incoming fuel pressure to mix the additive thoroughly throughout the tank.
