Product Information
Full details
The Carlube Classic Multigrade Oil - 20W50 is specifically formulated for veteran, vintage, and classic cars that require higher viscosity mineral oils. It provides essential lubrication for naturally aspirated 4-stroke petrol and diesel engines, as well as manual gearboxes from older vehicles. While it offers excellent protection for treasured classics and ensures rapid circulation in colder conditions, its non-detergent formulation means it's not suitable for modern engines with emission control systems.

FAQs
What makes this oil different from modern engine oils?
Modern oils are typically synthetic or semi-synthetic with detergents to clean engines and meet strict emissions standards. Carlube Classic 20W-50 is a mineral-based, non-detergent oil with a higher viscosity, specifically designed to suit the older engine technology and lubrication requirements of classic vehicles without causing damage.
Can I use this oil in my classic motorcycle?
This oil is designed for classic cars. Motorcycle engines, especially those with wet clutches, have very specific lubrication needs. Always refer to your motorcycle's service manual for the correct type of oil.
Is it safe to use detergent oil in my classic car?
Generally, it is not recommended unless specified by the vehicle manufacturer. Detergent oils can break down carbon deposits and sludge that have built up over decades, potentially leading to blocked oil passages, oil leaks, or increased wear.
What does 'non-detergent' mean for my engine?
A non-detergent oil provides lubrication without cleaning additives. This is beneficial for classic engines where removing established deposits could cause harm. It means the oil focuses purely on providing a protective film.
How often should I change this oil in my classic car?
Consult your vehicle's original manual for the recommended interval. Classic cars often require more frequent oil changes than modern vehicles, typically every 3,000 miles or annually, whichever comes first, due to the operating conditions and the oil's formulation.
Can this oil be used in both petrol and diesel classic engines?
Yes, this oil meets API SJ (for petrol) and CF (for diesel) specifications, making it suitable for naturally aspirated 4-stroke petrol and diesel engines of the classic era.
Troubleshooting
Engine noise increases after oil change.
Ensure the correct viscosity (20W-50) was used and that the oil level is correct. If the vehicle is very old, check if existing internal deposits are being disturbed by a slightly different base formulation, though this is unlikely with a non-detergent oil. If noise persists, consult a classic car specialist.
Oil pressure seems low.
Verify the oil level is correct. Check the oil pressure gauge for accurate readings. Ensure the oil filter (if fitted) is not blocked. Low oil pressure in classic cars can also indicate engine wear, which may require mechanical attention beyond lubrication.
Difficulty starting in cold weather.
While 20W oil offers better cold flow than a straight monograde, ensure the battery and ignition system are in good condition. The oil's 20W rating is intended to aid circulation in cooler temperatures compared to thicker alternatives.
Pros and Cons
Pros
- Specifically formulated for the unique needs of classic vehicles.
- High viscosity protects older engines and gearboxes.
- Non-detergent formula prevents disruption of existing engine deposits.
- Ensures good oil circulation in colder weather.
- Helps prolong the life and performance of classic cars.
Cons
- Not suitable for modern vehicles with emission control systems.
- Only suitable for naturally aspirated 4-stroke engines.
- Requires careful selection based on the vehicle's original specifications.
- May not offer the same level of wear protection as modern synthetic oils in extreme conditions.
Setup, Compatibility & Care
Compatibility:
- Engines: Suitable for naturally aspirated 4-stroke petrol and diesel engines manufactured for use with non-detergent mineral oils, typically from the veteran, vintage, and classic car eras (pre-1960s). Always consult your vehicle's original service manual to confirm oil type and viscosity requirements.
- Gearboxes: Suitable for manual gearboxes of the same era that require a similar viscosity oil.
- Modern Vehicles: Not suitable for modern cars, trucks, or motorcycles, especially those with turbochargers, catalytic converters, diesel particulate filters (DPFs), or other emission control systems. Using this oil in a modern vehicle can lead to significant engine damage and failure to meet emissions standards.
Usage and Care:
- Oil Changes: Follow the manufacturer's recommended oil change intervals for your specific classic vehicle. Due to the non-detergent formulation, regular changes are important to remove contaminants.
- Storage: Store the oil in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the container is tightly sealed to prevent contamination.
- Disposal: Dispose of used engine oil responsibly. Contact your local waste disposal facility or auto parts store for proper recycling or disposal methods.
