FAQs
How much CVL should I use?
The standard dosage is 250ml of CVL treats 20 litres of fuel.
Can I use Millers Oils CVL in my car with a catalytic converter?
Yes, but it is only recommended for occasional use. Prolonged use may affect the catalytic converter's efficiency.
Will CVL damage my engine?
No, CVL is designed to protect engines, particularly against detonation and valve seat recession when running on unleaded fuel. It does not contain harmful components for the engine itself.
Can I mix CVL with other fuel additives?
It is generally not recommended to mix different fuel additives without consulting the manufacturers of each product, as their interactions are not guaranteed.
How does CVL protect against valve seat recession?
CVL contains components that lubricate the valve seats, providing a protective barrier similar to that offered by lead in traditional fuels, thus preventing wear.
What octane boost does CVL typically provide?
Millers Oils CVL typically adds approximately 3 octane points to the base fuel rating.
Is this product suitable for E10 fuel?
Yes, CVL protects against the corrosive effects of ethanol found in E5 and E10 pump fuel.
Troubleshooting
Engine running rough after adding CVL
Ensure the correct dosage was used (250ml per 20 litres of fuel). If the dosage was too high, the engine management system might need time to adjust, or consider topping up with fresh fuel without additive.
No noticeable performance difference
The octane boost is subtle (typically 3 points) and designed to prevent issues rather than dramatically increase power on its own. Benefits are most noticeable when ignition timing is advanced. Ensure the fuel was mixed thoroughly.
Fuel cap not sealing properly after adding
Ensure the additive has fully entered the tank and the fuel cap is screwed on correctly and securely. Check the fuel cap seal for any damage.
