5W-40 Engine Oil
5W-40 engine oil for Defender TD5 and Discovery 2 TD5 servicing, top-ups and tuned or hard-worked engines, including Ravenol VMO and USVO RUP.
Start with the required oil specification and intended use, then check the product page for approvals, ACEA and API classifications, bottle size and engine fitment. Oils sharing the same 5W-40 viscosity are not automatically interchangeable, and VW 505.01 status should be checked where it forms part of the TD5 oil choice.

Find the right 5W-40 engine oil
Select the oil by engine specification and intended use rather than viscosity alone. Ravenol VMO covers normal TD5 servicing, top-ups and demanding road or working use, while Ravenol RUP sits at the more specialised end for highly tuned and competition engines.
| Job | Best place to start | Check before ordering |
|---|---|---|
| TD5 oil service | Ravenol VMO 5W-40 engine oil – 5L | Required specification and the total quantity needed with an oil-filter change |
| TD5 oil top-up | Ravenol VMO 5W-40 top-up oil – 1L | Match the oil already being used and confirm the required specification |
| Tuned, competition or extreme-use engine | Ravenol USVO RUP 5W-40 racing oil – 4L | Engine build, intended use, required specification and complete service quantity |
Check 5W-40 engine oil fitment before ordering
The viscosity grade is only one part of the oil specification. Confirm the exact engine, required approvals and service quantity before selecting an oil, particularly where the vehicle has been remapped, modified or built for competition use.
Engine
Identify the exact engine fitted rather than selecting oil from the Defender or Discovery model name alone.

5W-40 viscosity and oil specifications
The 5W-40 grade describes the oil’s viscosity characteristics, but it does not confirm that every 5W-40 oil meets the same engine requirements. Use the approvals and specifications on the individual product page to distinguish between VW 505.01-approved service oil and more specialised racing formulations.
| Product information | What to check |
|---|---|
| Viscosity grade | Confirm that 5W-40 is appropriate for the engine, operating conditions and servicing requirements. |
| Manufacturer approvals | Distinguish formal manufacturer approvals from specifications shown only as recommendations. |
| ACEA and API classifications | Compare the stated classifications with the engine’s servicing requirements. |
| Intended use | Check whether the oil is intended for routine servicing, top-ups, tuned road engines or competition use. |
