TD5 servicing usually comes down to three decisions: which engine oil to use, which filters to fit, and how often to change them. Get those right and the TD5 is a tough, long-lived engine. We regularly see well-maintained Defender and Discovery 2 TD5s still working hard at high mileages because they have been serviced properly with quality oil and filters.
The difficult part is product choice. The price difference between oils and filters can be huge, but the cheapest option is rarely the best way to look after a TD5. The original handbook guidance also reflects older oil specifications, so it is worth choosing proven modern oils from reputable brands, fitting quality filters, and servicing the engine at sensible intervals rather than trying to stretch every service as far as possible.
Which oil is best for the Td5?
If you look in the Land Rover handbook or RAVE, you will see engine oil recommendations based on older ACEA categories and viscosity ranges linked to ambient temperature. That information is still useful background, but TD5 oil choice today is better treated as a balance of specification, brand quality, engine condition and how the vehicle is used.
For normal TD5 servicing, a good quality 5W-30 or 5W-40 engine oil from a reputable brand is a sensible choice. We stock Rock Oil Synthesis F 5W-30 as our standard TD5 engine oil option and Ravenol VMO 5W-40 as our preferred premium option.
Rock Oil Synthesis F 5W-30 is a good standard oil for routine service use where an ACEA A5/B5 or Ford M2C913 specification oil is suitable. It gives a more affordable option without dropping into unknown, white-label or bargain-basement oils.
Ravenol VMO 5W-40 remains our preferred premium TD5 oil. It meets VW 505.01 and has a strong high-temperature/high-shear viscosity figure, making it a good choice for tuned engines, towing, hard use, higher-mileage vehicles, or simply where you want the oil we consider the best option in our range.
The important point is not just the viscosity printed on the label. Use a reputable oil, change it at sensible intervals and fit decent filters. A good oil changed regularly is a better approach than chasing the longest possible drain interval or buying the cheapest oil that happens to appear in a generic lookup tool.
The handbook viscosity chart is still useful for showing how Land Rover related oil grade to ambient temperature, but modern oil choice is about more than just viscosity.
Ravenol VMO is our preferred premium Td5 engine oil.
RAVENOL VMO 5w40
With a higher Viscosity Index Ravenol VMO will hold its viscosity much better. We recommend this oil for all Td5 engines, tuned or standard.
| Density @ 20 °C | 0.848 g/cm3 |
| Viscosity @ 100 °C | 13.3 cSt |
| Viscosity Index | 170 |
| HTHS (High Temperature High Shear) Viscosity at 150°C | 4.0 mPa.s |
| Total Base Number (TBN) | 8.7 mg KOH/g |
Which Td5 filters should you choose?
Price has a big influence on servicing choices, whether you are buying oil or filters, but cost should not be the only deciding factor. Good quality filters matter on a TD5, and saving a small amount on cheap filters is rarely worth it.
For TD5 servicing we mainly stock MANN and MAHLE filters. Both are well-made, proven filter brands and the sort of parts we are happy to use ourselves. There are plenty of cheaper filters on the market, but quality can vary more than many people realise.
To see the difference for ourselves, we bought a range of TD5 oil filters from different suppliers and cut them open for comparison. The variation in construction was surprisingly obvious, and the MANN and MAHLE cartridge oil filters stood out as some of the best made.
For air filters, a good quality paper filter is still the right choice for most vehicles. We also like ITG air filters, particularly on tuned TD5s, where they offer a well-made, reusable, UK-made alternative.
How often should you service your Td5?
If you read the Land Rover handbook, you will see engine oil change intervals of 20,000 km / 12,500 miles or 12 months, with some filters listed at different intervals. That guidance was written when these vehicles were new, and we do not think it is the best approach for a 25-year-old TD5 being used in the real world today. In practice, if you are changing the engine oil, it makes sense to change the main service filters at the same time rather than stretching them for the sake of a small saving.
For most TD5s, we consider around 6,000 miles to be a much more sensible service interval for normal use, or at least once a year if mileage is lower. Vehicles used for towing, hard work, short journeys or very high annual mileage may benefit from more frequent servicing.
A TD5 service is not especially expensive if you are doing it yourself, which is one reason many people change all the filters together rather than leaving one behind until next time. Keeping the engine on clean oil and decent filters is simple preventative maintenance.
Oil condition can give clues about how overdue a service may be, but mileage, time and usage are still better guides. If the oil is heavily contaminated and clearly past its best, the engine is ready for fresh oil and filters.
If you are servicing the vehicle yourself, make sure the waste oil is disposed of properly through the correct local facilities. Many recycling centres accept small quantities of used engine oil.
Other fluids
Engine oil and filters are the main focus of most TD5 services, but they should not be the only fluids you think about. Coolant, brake fluid, clutch fluid, gearbox oil, transfer box oil and axle oils all need checking and renewing at sensible intervals, especially on older vehicles where age, use and contamination can affect fluid condition.
Propshaft greasing is another job that is easy to overlook during routine servicing. If your vehicle has greaseable joints, use a good quality grease and make sure fresh grease is worked through the universal joints. Sliding joints should be greased carefully rather than overfilled. Neglecting propshaft maintenance will shorten the life of even a good quality shaft.
This Td5 was slightly overdue a service....

The range includes straightforward filter kits and premium branded options, including our all-MANN-FILTER TD5 service kit for customers who want consistent premium filter quality across the full service.
Td5 Recommended Fluids Quick Reference
The fluid recommendations below are based on the oils, fluids and greases we currently use and recommend for TD5 servicing. Some differ from the original handbook recommendations because oil specifications and product availability have moved on since the Defender TD5 and Discovery 2 TD5 were new.
The section below is intended as a practical product reference for wider TD5 servicing, not just an engine oil change
Td5 Engine Oil - Defender or Discovery
For normal Td5 servicing, use a good quality 5W-30 or 5W-40 engine oil from a reputable brand. Rock Oil Synthesis F 5W-30 is our standard option; Ravenol VMO 5W-40 is our preferred premium option.
7.2 - 8.2L required.
Rover Differentials (inc. Salisbury)
80w-90 / 75w-90 or just plain EP90 is fine. This should be a GL-5 oil. Mineral is best, and only mineral should be used in locking diffs.
LT230 Transfer Box
80w-90 / 75w-90 or just plain EP90 is fine. This should be a GL-4 oil. Mineral is best.
R380 Gearbox
MTF-94 should be used, although ATF Dexron III was specified in earlier models. We have found MTF-94 to be better for the gearbox, and ATF to be better for the driver (slightly smoother gear changes when cold). There are many oils that claim to meet MTF-94, some are just a 75w80 gear oil, some are even a 10w40 engine oil! Stick to reputable brands. MTF-94 is a 75w80 but with special additives.
ZF 4HP22 Automatic
ATF Dexron III is specified in the manual, however we use a fully synthetic ATF by Ravenol, specifically developed for 4HP and 5HP gearboxes. This offers much better protection.
Around 6L will be needed for a change as you cannot fully drain the fluid. The full capacity is 9.7L
Brake Fluid
DOT 4 brake fluid should be used. Don't skimp on this, you won't need much and cheap brake fluid doesn't last.
DOT 5.1 brake fluid can also be used, however do not confuse this with DOT 5 which is completely different and should not be used.
Avoid Mannol 3002 Brake Fluid DOT 4 (see here why)! It should not even be on sale anywhere. Cheap oils are cheap for a reason. You can check out a prospective oil manufacturer here.
Active Cornering Enhancement (ACE)
A cold climate power steering fluid should be used. If this is not available then ATF can be used, though this is not recommended.
Power Steering
A good quality ATF (Dexron III) should be used. Cold climate power steering fluid can also be used.
Coolant
Coolant containing organic additive technology (OAT) should be used in the Td5. Mix 50/50 - 10-15 litres of mix fills the system. For best results mix with distilled water.
Swivel Housings & CV
Since Land Rover did away with the drain and level plugs on the Defender swivel housings it's not practical to top up. When replacing the swivel housing grease use either Morris K48 or the Land Rover equivalent.
Grease
Parts such as universal joints, greaseable track rod ends etc should be regularly greased. We highly recommend Morris K48 which we use for all greaseable parts, nuts, bolts etc.
