Loader out on a tough grade and your pins are hammered loose by noon? You’re not alone. The real culprit behind so many shop headaches is grease squeeze-out—and it’s showing up in downtime, parts bills, and those repeat calls for extra lube.
Not-So-Fun Facts from the Field
- You grease a joint, head to the job, and the pin still chatters by lunchtime.
- After one mucky day, fresh grease is gone before the bucket’s even half-full.
- Working uneven ground near Montgomery? Shock loads pound last night’s grease straight out of the bushings.
Why Flimsy Grease Isn’t Earning Its Keep
“Whatever’s on hand” might be fine for mowers—but not for loaders pushing heavy dirt all day.
- Wet spring? Washout kills protection.
- Dust and gravel? Turns old grease into grinding paste.
- Cold snaps? Turns cheap grease into wax that won’t flow.
When the grease fails, so do pins, bushings, and eventually your patience.
All Calcium Sulfonate Greases Are Not Created Equal
Ever wonder if all calcium sulfonate greases are the same? Muscle Extreme-Lift EL-10™ claims to be built for pressure. AMSOIL’s 100% Synthetic Polymeric Off-Road Grease goes head-to-head—here’s how they actually compare:
| Performance Test | AMSOIL Synthetic | Muscle EL-10™ |
| Timken OK Load | 75+ lbs | 60 lbs |
| Four-Ball Weld Point | 620+ kgf | 500+ kgf |
| Four-Ball Wear Scar | < 0.45 mm | 0.50 mm |
| Dropping Point | 650°F | >500°F |
| Water Washout | 1% | 1% |
| Moly Content | 5% | 0% |
| Base Oil Type | 100% Synthetic | Conventional |
| Price (per cartridge) | Lower | Higher |
Base oils matter:
A full synthetic base resists breakdown, oxidation, and thickening even under heavy loads, while conventional oils are more likely to degrade in high temperatures and demanding environments.
Specs That Actually Matter
- Timken OK Load: Survives loader drops, not just garden use.
- Weld Point: Resists serious pressure; less worry, more work.
- Wear Scar: Less long-term pin and bushing pain.
- Dropping Point: Won’t melt out mid-job.
- Moly: Solid backup for sliding pressure.
- Synthetic Base: Flows and stays put, even when conditions change.
Local Crew: How Grease Cut Their Maintenance in Half
A crew based just outside Middletown used to lube pins twice per shift in damp weather. Switched to synthetic off-road grease—now it’s just once a day, with fewer breakdowns and less wasted labor.

Loader Grease FAQ: Real Answers, No Sugarcoating
❓ Why do my pins wear faster after spring storms?
That washout wipes out your grease’s best defense, and the morning’s work disappears by noon.
❓ Synthetic vs. conventional: Worth the switch or just more blog hype?
Crews running heavy jobs say the difference is clear after a week—better flow, sticks to pins, and reduces call-backs.
❓ Can I mix my old grease with the new stuff?
You could—but mixing is a gamble. Purge if you can and check for soft spots or leaks early.
❓ Fastest way to test cold weather performance?
Leave a tube in the truck overnight. If it won’t pump in the morning, change your grease.
