What oil does a Ford Mondeo 1.8 TDCi take?
The Mondeo 1.8 TDCi typically requires a 5W-30 fully synthetic engine oil that meets Ford’s WSS-M2C913-C specification, with newer engines sometimes requiring WSS-M2C913-D. Older manuals may reference WSS-M2C913-B.
Oil grade and Ford specification
Modern diesel engines like the 1.8 TDCi rely on a stable, low-ash synthetic oil to protect the turbo and emissions system. The key is ensuring the oil’s viscosity (5W-30) and its Ford specification match what the manual states for your vehicle’s year and market. Always check the owner’s manual or the oil cap label for the exact requirement.
Below are the typical specification options you may encounter. Note that availability depends on model year and market.
- 5W-30 fully synthetic oil that meets Ford WSS-M2C913-C (or the newer WSS-M2C913-D) specification.
- In some older manuals or markets, WSS-M2C913-B may be listed; confirm against your specific vehicle documentation.
- In very hot climates or under heavy load, 5W-40 can be acceptable if approved for your engine by Ford and aligned with the same WSS-M2C913 family specification; verify with your manual or dealer.
Using the correct oil specification matters for engine protection, fuel efficiency, and compliance with emissions systems. If the wrong oil is used, it can affect performance and potentially warranty coverage.
Practical confirmation and maintenance considerations
To be certain you have the right oil, verify three sources: the owner’s manual, the oil filler cap on the engine, and the label on the oil container. If there is any doubt, contact a Ford dealer or a qualified mechanic who can confirm the VIN-specific requirement for your Mondeo.
Tips for selecting and using the oil
- Always look for the viscosity 5W-30 together with the Ford specification (WSS-M2C913-C or -D) on the product label.
- Choose a fully synthetic oil for optimal protection and longer service intervals, especially on diesel engines with turbochargers.
- Follow Ford’s recommended service intervals and adjust for climate or severe driving conditions as advised in your manual.
In summary, the Ford Mondeo 1.8 TDCi generally calls for a 5W-30 fully synthetic oil meeting WSS-M2C913-C or the newer WSS-M2C913-D specification. Always verify the exact requirement for your year and market to ensure compatibility and performance.
Summary
For a Ford Mondeo 1.8 TDCi, use 5W-30 fully synthetic oil that meets Ford’s WSS-M2C913-C specification, with WSS-M2C913-D as the updated standard for newer vehicles. Some very early models may cite WSS-M2C913-B. Confirm the exact specification in your owner’s manual or with a Ford dealer to ensure the correct oil for your VIN and climate.
What kind of oil does a Ford Mondeo 1.8 TDCi take?
Recommended for OEM applications requiring a 5w30 viscosity, predominantly for Ford, Jaguar Land Rover and Asian manufacturers.
Can you use 5W-30 instead of 5W-20 in a Ford Focus?
Yes, you can likely use 5W-30 instead of 5W-20, but you should always check your owner's manual or the oil cap first to confirm the correct viscosity for your specific Ford Focus model and engine, as some models (especially turbo or high-performance variants) specifically require 5W-30, while others like the 1.0L or certain base models recommend 5W-20. Using a slightly thicker 5W-30 oil may slightly reduce fuel efficiency but should still provide adequate lubrication and protection, while using 5W-20 will maximize fuel economy.
Considerations when switching
- Check your manual: This is the most important step to avoid potential issues like reduced fuel economy or incorrect lubrication for your specific engine.
- Engine protection: A thicker oil like 5W-30 offers a thicker film at operating temperature, which some argue provides better protection, especially in very hot climates.
- Fuel efficiency: A thinner oil like 5W-20 is designed to reduce internal friction and maximize fuel economy, which is why it's often recommended by manufacturers.
- Engine performance: While 5W-30 should not damage your engine, some drivers have reported that thicker oil can cause cold-start rattle in certain engines or a minor reduction in performance.
- Other factors: The presence of a turbocharger, the age and mileage of your engine, and your local climate can all influence which oil is best suited for your vehicle.
In summary
While 5W-30 is likely a safe option for many Ford Focus models, it's always best to confirm your vehicle's specific requirements in the owner's manual or on the oil cap before making the switch. If your manual specifies 5W-20, using 5W-30 will likely cause a slight decrease in fuel economy.

Is the Ford Mondeo 1.8 TDCi engine reliable?
Yes, generally very reliable, but that 1.8 TDCi engine did have some issues with the fuel injection system, the dual mass flywheel and the turbo, so if you could instead track down one of the 2.0 TDCi models, you'll be getting a slightly better, more robust car.
