EP 140 Gear Oil: Specification, Uses & Bulk Price
EP 140 gear oil is a heavy extreme-pressure mineral gear lubricant at SAE 140 viscosity (roughly ISO VG 320+), used in slow-turning, heavily loaded final drives and axles on construction and earthmoving equipment. This page covers its specification, where it is used, how it compares to EP 90, and bulk pricing from a Mumbai manufacturer.

EP 140 Gear Oil Uses
EP 140 is the heavier of the two common EP gear grades and is specified where the final drive or axle is slow-turning and carries high shock loads, which is typical of crawler final drives, wheel-end reduction gears and heavily loaded differentials on excavators, cranes, tippers and dozers. The thicker film holds up under the momentary shock loading that occurs when a bucket digs into hard ground or a tipper axle takes a full load over rough terrain, where a lighter oil would be squeezed out from between the gear teeth. As with EP 90, always confirm the OEM manual before switching grades or GL rating, since running the wrong viscosity in a final drive either starves the gears under load or adds unnecessary drag and heat.
EP 140 vs EP 90 — quick answer
EP 140 is the heavier grade, used in slow, heavily loaded final drives and axles that run hotter under shock load; EP 90 is lighter and used in manual gearboxes and lighter differentials where the manual calls for SAE 90. For the full breakdown of when to use each, see EP 90 vs EP 140 gear oil.
EP140 Gear Oil Equivalents in India
Buyers searching for a branded EP140 alternative often look for Shell Spirax EP 140, Servo Gear Oil EP-140, or Castrol EPX 140. All are SAE 140 (≈ ISO VG 320+), GL-4/GL-5 extreme-pressure mineral gear oils built to the same API performance level as KE EP 140 — the difference is packaging, brand markup and distributor margin, not the additive chemistry.
| Brand | Product | Grade / Spec |
|---|---|---|
| Shell | Spirax EP 140 | SAE 140, GL-4/GL-5 |
| Servo | Servo Gear Oil EP-140 | SAE 140, GL-4/GL-5 |
| Castrol | EPX 140 / Gear Oil 140 | SAE 140, GL-4/GL-5 |
| KE | EP 140 Gear Oil | SAE 140, GL-4/GL-5 |
KE EP140 = same API GL-4 spec, direct manufacturer price. Bulk buyers switching from a branded EP140 keep the identical gear protection at a manufacturer-direct rate, with a free sample available for site trials before committing to a drum order.

We deliver across Mumbai, Navi Mumbai, Thane and the wider MMR, direct from the plant with no distributor markup. First orders are prepaid; once 100 orders are on record, repeat buyers move to standard credit terms. A free sample is available for site trials before you commit to a bulk order, drum, pail or tin, whichever pack size suits your consumption.
Frequently asked questions
What is EP 140 gear oil used for?
Slow-turning, heavily loaded final drives, wheel-end reduction gears and axles on excavators, cranes, tippers and dozers.
What does EP mean in EP 140 gear oil?
Extreme Pressure. It refers to the sulphur-phosphorus additive package that protects hypoid and angled gear sets under shock loading.
What is the GL rating of EP 140 gear oil?
Typically GL-4 or GL-5, depending on the formulation. Check your equipment manual before switching grades.
Is EP 140 the same as EP 90?
No. EP 140 is a heavier viscosity grade (SAE 140, approximately ISO VG 320 plus) for slow, heavily loaded final drives. EP 90 is lighter (SAE 90, approximately ISO VG 150) for gearboxes and lighter differentials.
What pack sizes are available?
1L tin up to 210L drum, direct from the manufacturer.
