What oil does a transit custom use?

The Transit Custom typically uses 5W-30 fully synthetic engine oil for its EcoBlue diesel engines. Always confirm the exact grade and Ford specification in your owner’s manual or with a Ford dealer, as oil requirements can vary by model year and market.


Overview: oil grade and Ford specifications for the Transit Custom


Below are the oil guidance commonly applicable to the most recent EcoBlue-engined Transit Customs. Always cross-check with your specific vehicle documentation, since specifications can shift between generations and regions.



  • 5W-30 fully synthetic engine oil, low-SAPS, meeting Ford specification WSS-M2C934-B (or the current Ford-equivalent specification listed for your vehicle).

  • For older generations or certain markets, the manual may reference an earlier Ford specification (for example WSS-M2C913-C) or an equivalent specification. Verify the exact requirement in your owner’s manual or from a Ford dealer.


In short, the standard recommendation for most modern Transit Custom EcoBlue diesels is a 5W-30 fully synthetic oil that meets Ford’s current specification. If you have a pre-EcoBlue engine or a region with a different specification, consult the manual to confirm the exact grade and spec.


How to confirm the exact oil for your Transit Custom


Follow these steps to ensure you’re using the correct oil for your specific vehicle:



  1. Check your owner’s manual or the Ford official service information for the exact oil specification and viscosity listed for your model year and market.

  2. Identify your engine type and generation (for example, EcoBlue 2.0 diesel) since different generations may have different requirements.

  3. Look for the recommended viscosity: most current EcoBlue engines call for 5W-30, but verify if your manual lists a different grade for your climate or usage.

  4. Choose oil that is fully synthetic, low-SAPS, and meets the Ford specification stated for your vehicle (e.g., WSS-M2C934-B or its current equivalent).

  5. Prefer oils from reputable brands and consider OEM-approved or Ford-approved oils; avoid off-spec blends that don’t meet the required Ford spec.

  6. If in doubt, contact a Ford dealer or authorized service center to confirm the correct oil type for your exact vehicle.


Using the correct oil helps protect the diesel particulate filter, maintain engine performance, and support proper oil-drain intervals as specified by Ford.


Summary


For most modern Ford Transit Custom models with EcoBlue diesel engines, the recommended oil is 5W-30 fully synthetic, low-SAPS, meeting Ford specification WSS-M2C934-B or the current equivalent. Always verify the exact grade and specification in your owner’s manual or with a Ford dealer, especially if you have an older model or a market with a different specification.

What oil do I put in my Ford Transit Custom?


If you're looking for a standard oil for a Ford Transit Custom, 5w30 meets all the requirements for efficient operation.



What is the best oil for a Ford diesel engine?


SAE 15W-40 SUPER DUTY DIESEL MOTOR OIL
It is particularly recommended for use in Ford vehicles equipped with Power Stroke® Diesel engines, as well as in other diesel engine applications where the manufacturer recommends an oil of this viscosity grade and quality.



Is 5W-30 oil ok for diesel?


You can put 5W-30 in a diesel engine only if the vehicle's owner's manual specifically recommends it, as it is generally suitable for light-duty engines, but not for heavy-duty ones. Always check your owner's manual to confirm the correct viscosity and specifications for your engine. 
Considerations for using 5W-30 in a diesel engine:

  • Check your owner's manual: This is the most crucial step. The manufacturer's recommendation is the only definitive guide for your specific vehicle. 
  • Light-duty vs. heavy-duty: 5W-30 is often suitable for light-duty diesel engines in cars and pickup trucks. However, heavy-duty diesel engines typically require a thicker oil (like 15W-40) due to higher operating temperatures and pressures. 
  • Diesel-specific additives: Some diesel oils contain specific additives not found in gasoline oils. Using a non-diesel rated 5W-30 could be problematic depending on your engine's requirements and needs. 
  • Environmental conditions: 5W-30 is often recommended for its ability to flow well in colder temperatures, which can improve cold starts. 
  • Potential downsides: Using a thinner oil than recommended can lead to lower oil pressure and potentially faster wear on some components. Some sources suggest that for high-mileage engines, a slightly thicker oil like 5W-40 can help reduce leaks. 



What oil for Ford Transit Custom 2.2 diesel?


SAE 5W-30
Use oil and fluids that meet the defined specification and viscosity grades. Note: If you are unable to find an engine oil that meets the specification defined, you must use an SAE 5W-30 engine oil that meets the specification WSS-M2C913-C or D.
