FAQs

What does 'TITANIUM FST' mean?

TITANIUM FST (Fluid Strength Technology) is Castrol's proprietary technology that enhances the oil's strength and resilience, providing better protection under high pressure by doubling the oil film's strength.

Is this oil suitable for all diesel engines?

No, it is specifically formulated for modern diesel engines that require an ACEA C1 or C2 specification, often found in vehicles with exhaust after-treatment systems like DPFs. Always check your vehicle manual.

What is the difference between ACEA C1 and C2 specifications?

ACEA C1 is a low SAPS (Sulphated Ash, Phosphorus, Sulphur) oil designed for maximum fuel economy and emissions system protection. ACEA C2 is also low SAPS but offers a balance between fuel economy and performance.

Can I use this oil if my car requires a different specification?

It is strongly advised not to use this oil unless your vehicle manufacturer specifically recommends ACEA C1, STJLR.03.5005, or WSS-M2C934-B. Using the incorrect oil can harm your engine.

How often should I change this engine oil?

Refer to your vehicle's owner's manual for the recommended oil change intervals. These can vary based on driving conditions and mileage.

What does 'CO2 Neutral' certification mean for this oil?

It means that Castrol has offset the carbon emissions associated with the production and lifecycle of this oil by investing in projects that reduce greenhouse gas emissions, according to the highest global standards.

Where can I find the batch number or quality verification details?

Product quality is verified using Castrol's Optical Particle Measurement System. Specific batch numbers are typically found on the packaging.

Troubleshooting

Engine oil warning light remains on after oil change

Ensure the correct oil level is filled. The light may also need to be reset manually according to your vehicle's service manual.

Engine noise or rough running

Verify that the correct oil specification (ACEA C1, JLR, Ford) and viscosity (5W-30) were used. If not, the oil should be changed immediately to the manufacturer's recommendation.

Oil leaks observed

Check that the oil drain plug and filter are properly tightened. Leaks could also indicate a need for new seals or gaskets, which should be addressed by a qualified mechanic.

Pros and Cons

Pros

  • Maximizes both short and long-term engine performance.
  • Reduces engine deposits for improved engine response.
  • Provides complete protection under diverse driving conditions and temperatures.
  • Sustains peak performance even under high-pressure situations.
  • Independently verified to improve engine efficiency.
  • Ensures product quality through advanced verification methods.

Cons

  • Not suitable for all engine types; requires specific ACEA C1/C2 or manufacturer approvals.
  • Lower viscosity may not be appropriate for older engines with wider tolerances.
  • Specialized formulation means it's crucial to verify compatibility before use.

Setup, Compatibility & Care

Compatibility: This oil is specifically recommended for vehicles requiring:

  • ACEA C1 or ACEA C2 specification.
  • Jaguar Land Rover engine oil specification STJLR.03.5005.
  • Ford WSS-M2C934-B specification.

Always consult your vehicle's owner's manual to confirm the correct oil specification before use. Using the wrong oil can lead to engine damage.

Filling: Follow your vehicle manufacturer's recommended oil change intervals and capacity. Ensure the engine is at a suitable temperature for draining old oil and that the oil filter is replaced concurrently. Use a clean funnel to pour the new oil.

Storage: Store the oil containers in a cool, dry place, away from direct sunlight and extreme temperatures. Keep them sealed when not in use.

Disposal: Dispose of used engine oil responsibly at an authorized recycling center. Do not pour used oil down drains or onto the ground.
