Protect Your Semi Truck with the Right Lubrication Products
August 2025
Why Lubrication Matters
Semi trucks operate under extreme pressure, heat, and load conditions. From the engine and transmission to the wheel ends and drivetrain, proper lubrication is what prevents unwanted contact, overheating, and early failure. Using the wrong lubricant, or not enough of it, can lead to total damage.
Common Lubrication Issues That Lead to Failures
Viscosity Breakdown: High heat conditions can cause engine oil to thin out, losing its ability to protect moving parts. Once the protective film breaks down, wear happens quicker.
Grease Separation: Under constant pressure or contamination, grease can lose its structure and effectiveness. Water intrusion and dust only make matters worse, especially in wheel bearings and fifth wheels.
Mixed Lubricants: Mixing different greases or oils can result in chemical incompatibility, leading to sludge, hardening, or complete failure. This often occurs during top-offs.

Prevent Lubrication Failures with Smart Product Choices
Here's how to extend service life and prevent breakdowns:
- Check compatibility: Always follow OEM specs when selecting fluids and greases.
- Use fresh, sealed products: Old or improperly stored lubricants degrade quickly.
- Upgrade to synthetics: Synthetic oils offer better protection in high-temp and long-drain intervals.
- Don't ignore grease points: Fifth wheels, slack adjusters, and suspension bushings often get overlooked.
