I’ve put together a section on Lubricants and Fluids that you may already use on your Land Rover and some that you may not but which could be useful. Obviously there are many brands of lubricant available so the ones listed below aren’t the only ones which will do the job but are the ones which I personally currently use. As always it is only a guide and you may find other products better suited to your needs, however if you’ve no idea what to use then this will be a good starting point.
A good quality mineral engine oil is the life blood of your engine. Choose which grade you require according to the ambient temp range in which your vehicle will be driven. Use the same grade in the oil bath air filter.
10W/40 or 10W/50 use in temp -20 to in excess of +30` C
15W/40 or 15W/50 use in temp -10 to in excess of +30` C
20W/40 or 20W/50 use in temp 0`C to in excess of +30` C
EP 80W/90 GL4 Spec is to be used in the main gearbox whereas either EP 80W/90 GL5 Spec OR GL4 Spec can be used in the front swivel housings, front and rear axles, transfer box, overdrive, steering relay and steering box. (To keep it simple and in case oil leaks between transfer box/gearbox/overdrive stick to GL4 Spec)
Lithium High melting point grease can be used everywhere including all ball joints, filling wheel hubs/wheel bearings, Lubricating prop shafts etc.
BRAKE AND CLUTCH FLUID
A DOT 3 spec non silicone brake and clutch fluid is to be used. If you want to use silicone brake and clutch fluid then ALL traces of non silicone fluid MUST be removed from the system first!
A standard ethylene glycol anti freeze (Blue coloured one) is to be used for all year round protection. I mix mine with soft tap water if possible to reduce scale build up in the system. Mix together first to ensure the correct ratio which should be a maximum of 50% antifreeze to 50% water. Beware this sweet tasting stuff is highly poisonous to animals and humans.
A general purpose all year round screen wash will suffice. Don’t be tempted to use cooling system anti freeze!
A penetrating fluid is used for spraying onto rusty fixings prior to removal, protecting electrical connections and water displacement from damp ignition circuits. (Hence the WD in WD 40.) Can be sprayed onto tools and allowed to dry to protect from rusting too.
ELECTRICAL CONTACT CLEANER
An electrical contact cleaner is useful for removing grease, dirt and oil from hard to access wiring connectors, earths, ignition switches and fuse boxes.
No Land Rover owner should be without this. Used when assembling components to ensure they do not corrode together to aid dismantling in the future. Such as nuts/bolts, ball joint threads, brake drum to hub face etc etc. Can be used on brake shoe to back plate contact points and on electrical earth points.
CORROSION BLOCK GREASE
A favourite of mine, this corrosion block grease is excellent for linkages, door hinges, sliding window runners etc as well as exposed chassis protection as it resists washing away. Can also be used as an assembly grease and will stop existing rust as well as preventing new. Wonderful stuff!
GENERAL LIGHT OIL
A general purpose light machine oil is handy for light lubricating jobs such as pedal hinges, hand brake lever pivots, speedo cable inners etc. Use on an oilstone when sharpening tools as well as when tapping new threads.
This spray grease is useful for hard to reach areas. Its good for door hinges, hand throttle assemblies, squeaky suspension bushes, diesel engine stop cables etc.
