Product Information
Full details
Carlube Triple R 20W-50 R-Tec 38 mineral oil is designed for classic and older vehicle engines that require a thicker viscosity for optimal lubrication and protection. It provides an excellent balance of anti-wear and detergency properties to prolong engine longevity, though users must verify that their vehicle manufacturer specifies the 20W-50 grade, as it is not suitable for most modern high-performance engines requiring low-viscosity synthetic oils.

Extended Product Information
FAQs
Is this oil synthetic or mineral?
This is a mineral-based engine oil formulated with advanced additives.
Can I use this in my modern car?
Generally no; most modern cars require low-viscosity synthetic oils. Consult your manual before use.
What do the API SB and CB ratings mean?
These are older service classifications for gasoline (SB) and light-duty diesel (CB) engines, typically found in older vehicles.
How often should I change this oil?
Follow your vehicle manufacturer's recommended service intervals, or every 3,000–5,000 miles for older vehicles.
Where is this oil manufactured?
Carlube Triple R oils have been manufactured in the UK since 1988.
Is it safe to mix this with other oils?
While it can be mixed with compatible oils, it is always best to perform a full oil and filter change to ensure maximum performance.
Troubleshooting
Engine oil pressure gauge reads lower than normal after change
Verify that your engine design requires 20W-50; if your engine was designed for thin oil, the oil pump may struggle to circulate this thicker grade efficiently.
Oil appears black shortly after an oil change
This is often normal in older engines as the high-detergency additives in Triple R oil work to clean out accumulated sludge from previous oil usage.
Pros and Cons
Pros
- Ideal for classic and older engine designs
- Effective at reducing engine sludge and internal deposits
- Strong protection against high-heat oxidation
- Manufactured in the UK with proven quality standards
Cons
- Not suitable for most modern cars requiring 0W or 5W grades
- Mineral base lacks the extreme cold-flow properties of full synthetics
- API SB/CB specifications are outdated for modern emissions-compliant engines
Setup, Compatibility & Care
To ensure proper performance, check your vehicle owner's manual to confirm that the engine is rated for 20W-50 viscosity. This oil meets API SB and CB specifications. When performing an oil change, ensure the engine is warm but not hot, drain the old oil completely, and replace the oil filter. After refilling, check the oil level on the dipstick on level ground to ensure it sits between the minimum and maximum marks. Store the container in a cool, dry place to prevent moisture ingress.
