Grease Comparison
Calcium Grease vs Lithium Grease for Industrial Use
Calcium and lithium are the two most common grease thickeners on Indian industrial sites. The choice between them comes down to two questions: how wet is the application, and how hot does it run. Calcium grease resists water better and costs less; lithium grease handles heat better and works across more applications. This page settles which to use where.
Wet and cool points suit calcium grease, which is more water-resistant and cheaper. Warm or mixed-duty points suit lithium grease, with its higher dropping point. For points that are both wet and warm, a lithium-complex grade bridges the gap.
Calcium vs lithium grease
| Property | Calcium grease | Lithium grease |
|---|---|---|
| Water resistance | Excellent | Good |
| Dropping point | ~90–110°C | ~185°C+ |
| Max operating temp | ~60–70°C | ~120–130°C |
| Mechanical stability | Moderate | Good |
| Multi-purpose suitability | Limited | Wide |
| Relative cost | Lower | Moderate |
Choose calcium grease when…
Water exposure is the main hazard and temperatures stay low. Calcium soap resists washout, so it suits water pumps, equipment exposed to rain and washdown, and low-speed points where heat is not a factor. It is also the cheaper option, which matters at volume. The well-known yellow/batata grease is a calcium grease, see calcium grease and yellow grease vs lithium.
Choose lithium grease when…
You need one grease for mixed duty and some of it runs warm. Lithium’s higher dropping point keeps it in place on bearings that heat up, and its mechanical stability holds up under working shear. For general multi-purpose service this is why lithium grades like MP3 are the site default rather than calcium.
The decision in one line
Wet and cool → calcium. Warm or mixed-duty → lithium. If an application is both wet and warm, lithium-calcium or lithium-complex grades bridge the gap, but for most sites the simple split above covers the decision. Do not run calcium grease above ~70°C and do not pay for lithium where a low-temperature wet point only needs calcium.
Compatibility and switching between thickeners
Calcium and lithium greases use different soap thickeners, and the two are not reliably compatible. Mixing them in the same point can break down the thickener structure so the blend softens and bleeds oil, leaving the bearing under-protected. When you change a point from calcium to lithium or back, purge the old grease completely, keep pumping fresh grease through until only the new grease shows at the seal, rather than topping up over the old.
For applications that genuinely see both water and heat, there are lithium-calcium and lithium-complex grades formulated to combine water resistance with a higher dropping point. These bridge the gap where a plain calcium grease would melt out and a plain lithium grease would wash off, but for the majority of points the simple wet-and-cool versus warm-or-mixed split decides the choice without needing a specialist grade.
Storage and shelf life
Store both greases in closed containers away from heat, water and dust. Calcium grease is the more heat-sensitive of the two in storage because of its lower dropping point, so keep it cool and check older stock for oil separation before use, a layer of oil on top means the grease has started to bleed and should be stirred back in or discarded if badly separated. Always decant with a clean scoop or pump; dipping a dirty tool into a drum contaminates the whole batch with grit that then ends up in your bearings.

Frequently asked questions
Which grease is more water-resistant?
Calcium grease. Calcium soap resists water washout better than lithium, which is why it is preferred for wet, low-temperature points.
Which grease handles heat better?
Lithium grease, with a dropping point around 185°C and above versus roughly 90–110°C for calcium.
Can I mix calcium and lithium grease?
Avoid mixing thickener types, they can be incompatible and soften. Purge the old grease before switching, or use a lithium-calcium grade designed for both.
Which is cheaper?
Calcium grease is generally cheaper and is the economical choice for wet, low-temperature, low-speed duty.
How do I tell calcium and lithium grease apart in the tin?
Calcium grease is usually pale yellow and softer; lithium grease is typically brown or amber and firmer at the same grade. Colour alone is not proof, though, the reliable way is the supplier’s datasheet showing the thickener type and dropping point. A dropping point near 90–110°C indicates calcium; around 185°C and above indicates lithium.
Which grease should a general workshop keep as default?
For mixed duty across a workshop, a lithium grease (such as an MP3 grade) is the better single default because it covers warm and higher-speed points as well as general ones. Keep calcium/batata grease alongside it specifically for wet, low-temperature points where it both performs better and costs less.
Is lithium-complex grease worth the extra cost?
For sealed bearings that run hot for long hours, yes, the higher dropping point of a lithium-complex grade keeps it in place where plain lithium would soften. For ordinary ambient-temperature points, plain lithium is sufficient and the complex grade is not necessary.
