Carlube Triple R 15W-40 is a high-performance mineral oil engineered for owners of older petrol and diesel engines seeking a reliable lubrication solution that balances protection with longevity. Ideal for high-mileage vehicles and classic cars, this oil excels at providing stable viscosity across varying temperatures, though it is specifically formulated for older engine technologies rather than modern high-performance units requiring low-viscosity synthetics.

Carlube Triple R 15W-40 is a premium mineral oil.
No, this oil is specifically formulated for older petrol and diesel engines and does not meet the requirements of most modern, low-viscosity engine standards.

The '15W' refers to the oil's flow at cold temperatures, while the '40' indicates its viscosity performance at high operating temperatures.
While it is technically possible to mix, it is not recommended as it will dilute the performance benefits of both oils. Always perform a full oil and filter change for best results.
Check oil levels to ensure you haven't underfilled; verify the oil filter is tightened correctly and is not leaking.
15W-40 is thicker than some modern alternatives, but if consumption persists, check for external leaks or worn valve stem seals common in high-mileage engines.
Before adding Carlube Triple R 15W-40, verify your vehicle's owner manual to confirm that a 15W-40 viscosity is recommended for your engine's specific temperature climate and mileage.
