Vehicle Greases
How to choose vehicle greases
Match sub-type to mechanism
Match the sub-type to the job. Grease for bearings, gear oil for diffs, additive for LS conversions.
Check for limited slip
Confirm if your diff is limited slip (LS). Without LS-rated oil or additive, you get clutch chatter.
Pick the viscosity grade
Weigh viscosity (75W-140 vs 75W-110). Thicker guards under load but lags in cold weather.
Synthetic or mineral
Choose synthetic versus mineral. Synthetic holds heat better, though some older kits prefer frequent mineral swaps.
Size and final check
Note the bottle size. A 500 ml gear oil tops up, but will not flush a full axle. Once you know your spec, the grid below lets you weigh these types side by side.
What's good
- Bearing grease in a 500g tub suits DIY hub and linkage jobs without a grease gun or press.
- Fully synthetic hypoid gear oil resists shear under diff load better than a basic mineral fluid.
- Limited slip axle additives let you convert standard oil for clutch diffs, avoiding a full fluid buy.
- Keeping dedicated vehicle fluids (grease, gear oil, hydraulic) on hand covers several service points at once.
Things to watch
- Bearing grease cannot fill a differential. It is the wrong medium for hypoid gears.
- Synthetic gear oil of the wrong viscosity (say 75W-140 vs 75W-110) can stiffen cold shifts if mismatched.
- Axle additives only work over a base oil that already meets the GL rating. They are not a cure alone.
- Hydraulic oil and gear oil look alike. Confusing the two wrecks seals, so keep the sub-types separate.
Care & maintenance
Seal grease tight
Reseal grease tubs after use. Water ruins the thickener and rusts bearings.
Store frost-free
Store gear oil and hydraulic bottles upright in a frost-free place. Cold thickens them and slows pours.
Keep fillers clean
Wipe filler necks before topping up. Grit in a hub or diff scores the surfaces fast.
Label your grades
Tag any mixed fluid with its grade (75W-140, etc) so later top-ups match.
