Protect your high-performance engine from the risks of modern fuel with Millers CVL. This competition-grade valve seat lubricant and octane booster is specifically formulated to allow classic and racing engines to run safely on super unleaded petrol, eliminating the threat of valve seat recession and premature guide wear.

Product Specs

• Type: Competition Valve Seat Lubricant (VSL) & Octane Booster
• Volume: 250ml
• Chemistry: Manganese-based (Tested & Approved by the FBHVC)
• Compliance: Fully compliant with MSA and FIA year 2000 fuel regulations
• Application: Suitable for all engines originally designed for leaded fuel

Why Choose Millers CVL?

• Engine Safety: Prevents "valve seat recession" by providing a protective coating on the valve seats, a vital requirement for heads without hardened inserts.
• Enhanced Performance: Acts as an octane booster to help prevent "pinking" or detonation in high-compression competition engines.
• Approved Technology: Uses advanced manganese chemistry approved by the Federation of British Historic Vehicle Clubs for maximum peace of mind.
• Versatile Protection: Reduces accelerated wear on valve guides and stems, maintaining engine tolerances even under the high thermal stress of racing.
• Regulated Compliance: Meets all relevant motorsport governing body standards, making it the legal and safe choice for historic competition.

Installation Tip: For optimum results, add the required amount of CVL to your tank before filling up with super unleaded to ensure thorough mixing. One 250ml bottle is typically designed to treat 20 litres of fuel for competition use, though ratios may vary for road applications.

Key Point: Provides the essential octane boost and lubrication needed to run competition engines on modern pump gas.
