Description
RAVENOL DOT 4 is a conventional glycol-based brake fluid for Land Rover brake and clutch hydraulic systems requiring DOT 4 fluid. It combines a high 271°C dry boiling point with a 169°C wet boiling point, good chemical stability and compatibility with brake-system components. For older and conventional Land Rover hydraulic systems, it is a strong service fluid without moving unnecessarily to a low-viscosity DOT 4 LV formulation.
Brake fluid gradually absorbs moisture during service, reducing its boiling point and increasing the risk of corrosion within hydraulic components. A complete fluid change restores fresh fluid throughout the system rather than simply topping up old, moisture-contaminated brake fluid. RAVENOL DOT 4 is miscible with other brake fluids meeting the same specification and can also be used in compatible hydraulic clutch systems requiring DOT 4.

Ravenol
Ravenol is our main lubricant brand for Land Rover servicing, covering engine oils, manual and automatic gearboxes, transfer boxes, differentials, ACE and power steering, brake fluid, coolant, grease and specialist workshop fluids.
We use Ravenol because the range lets us select the lubricant around the actual engine, gearbox, axle or hydraulic system rather than relying on viscosity alone. The result is a deliberately selected Land Rover range in which every product has a defined job, from TD5 engine oil and R380 MTF-94 to specialist ZF ATF, LT230 oil, limited-slip differential oil and later transfer-box fluids.
Why Twinwoods partners with Ravenol
Ravenol is a genuine German lubricant manufacturer, developing and producing its oils, fluids and greases in Germany. The range is backed by unusually detailed technical data, which matters to us because lubricant choice should be based on much more than the viscosity printed on the bottle.
We use Ravenol in our service kits, recommend it for the Land Rovers we specialise in and use it in vehicles we work on ourselves. More importantly, the range gives us properly specialised products for different engines, gearboxes, transfer boxes, axles and hydraulic systems rather than trying to make one generic lubricant cover everything.
Ravenol oils and fluids for Land Rover
| System | Ravenol products | What matters |
|---|---|---|
| Engine oil | VMO, RUP, Turbo-C HDC, TSi, FO, FLJ, VMP, SFE and Formel Extra | Engine, viscosity, specification, emissions equipment and how the vehicle is used |
| Manual gearboxes | MTF-2 / MTF-94 for the R380 and VSG 75W-90 for the Defender Puma MT82 | Gearbox type and complete lubricant specification rather than viscosity alone |
| Automatic gearboxes | ATF 5/4 HP and ATF Dexron III H | ATF 5/4 HP is our specialist choice for the Discovery 2 ZF 4HP gearbox, while Dexron III H covers compatible general ATF duties |
| Transfer boxes | MZG 80W-90 and VSG 75W-90 for the LT230, plus DTF-1 for compatible later active transfer boxes | Transfer box design and the fluid specification required by that particular unit |
| Axles and differentials | EPX 80W-90, VSG 75W-90, RHP 75W-90, LS 75W-90 and LS 80W-90 | Standard, ATB or limited-slip differential design together with the required viscosity and friction characteristics |
| ACE and power steering | SSF and ATF Dexron III H | Hydraulic system and the correct fluid specification |
| Brakes and clutch | DOT 4 LV and DOT 4 | DOT 4 LV is our main brake and clutch fluid, with conventional DOT 4 retained where appropriate |
| Cooling systems | C12+ OAT and C12evo Si-OAT coolant concentrates | Coolant technology, engine and the fluid already in the cooling system |
| Grease | MoS2 Multi-Purpose Grease, LI-86 Bearing & Propshaft Grease and HRG 2 Hot Red Grease | MoS2 for broad workshop and driveline use, LI-86 for bearings and universal joints, and HRG 2 for high-temperature grease duties |
| Workshop fluids | Professional Engine Cleaner and Winter Screenwash Concentrate | Purpose-specific maintenance products alongside the main lubricant range |
More than the correct number on the bottle
Two oils carrying the same viscosity grade can be very different products. Base oil, additive chemistry, volatility, viscosity stability, friction characteristics and manufacturer specifications all affect how a lubricant behaves once it is hot and working inside the component.
That is particularly important with Land Rovers. An R380 gearbox, LT230 transfer box, Rover differential, ZF automatic gearbox and electronically controlled later transfer box all place different demands on their lubricant. We select the Ravenol product around the component itself rather than simply finding the nearest familiar viscosity.
Identify the component
Start with the engine, gearbox, transfer box, differential or hydraulic system being serviced.
Match the specification
Check the complete ACEA, API, GL, manufacturer or transmission-fluid requirement rather than viscosity alone.
Consider vehicle use
Standard servicing, towing, off-road use and highly tuned engines can place very different demands on the lubricant.
Check existing fluid
Coolant, hydraulic fluids and specialist transmission oils should not be mixed simply because their colour or general description appears similar.
Ravenol engine oil
Our Ravenol engine-oil range runs from traditional oils for 200TDI, 300TDI and classic petrol engines through to specialist oils for TD5, Defender Puma TDCI and later Land Rover engines. Ravenol VMO 5W-40 remains our main TD5 recommendation, RUP 5W-40 covers very highly tuned TD5 engines, Turbo-C HDC 15W-40 is our preferred oil for standard 200TDI and 300TDI engines, while FO, FLJ, VMP and SFE cover the relevant later engine and emissions-system requirements.

Can I fit a part and then return it?
Please check fitment and suitability before installation.
Please do not fit or attempt to fit a part unless you intend to keep it.
Once a part has been fitted or an attempt has been made to fit it, it may be marked, contaminated, damaged or otherwise unsuitable for resale as a new part. We do not operate a used-parts or bargain-bin section, so a fitted or damaged part can have very little resale value.
Where your handling has reduced the value of the goods beyond what is reasonably necessary to inspect them, your refund may be reduced to reflect that loss in value.
