When it comes to maintaining your vehicle, selecting the correct lubricant is crucial. Tie rod ends, which are vital for steering and handling, need high-quality grease to perform effectively and last longer. There are two primary grease options: synthetic and petroleum-based. Each has its advantages depending on your vehicle’s requirements and driving conditions. Let’s take a closer look.
Features of AMSOIL and Kendall Greases
Two standout options in these categories include AMSOIL 100% Synthetic Multi-Purpose Grease NLGI #2 (synthetic) and Kendall L-427 Super Blu Grease (petroleum-based):
- AMSOIL 100% Synthetic Multi-Purpose Grease: Designed for high-performance applications, synthetic grease excels in extreme temperatures and heavy loads, offering superior wear protection and durability. It resists oxidation and corrosion, making it ideal for demanding environments, like off-road or high-performance vehicles.
- Kendall L-427 Super Blu Grease: A petroleum-based option, Kendall’s grease provides reliable protection against wear and tear for everyday automotive needs. Its thick consistency ensures solid lubrication under pressure and offers great value for routine maintenance.
Both products serve their own strengths, with synthetic greases tending to excel in high-stress or long-term applications, while petroleum-based greases meet the needs of more standard use cases.
Synthetic vs. Petroleum-Based Greases: A General Comparison
Performance and Longevity
Synthetic grease is engineered for advanced lubrication, helping minimize friction and wear even under challenging conditions. Its molecular stability allows it to last longer, reducing the need for frequent reapplication. Conversely, petroleum-based products perform well but may require more frequent maintenance in extreme environments or high-stress applications.
Durability in Harsh Conditions
Water, dust, and extreme pressure can wear down grease quickly. Synthetic formulations generally resist breakdown better, maintaining effectiveness in wet, dusty, or high-pressure scenarios. Petroleum-based greases still perform reliably in less demanding conditions, providing great value.
Temperature Stability
Synthetic grease outshines petroleum-based products in temperature extremes, maintaining a consistent protective film in both high heat and freezing conditions. Petroleum-based greases are suitable for moderate climates but can lose consistency in extreme cold or heat.
Versatility and Applications
Synthetic grease offers a wider range of coverage across automotive and industrial applications, including tie rod ends, wheel bearings, and suspension components. Petroleum-based grease is effective for most typical automotive uses but may not perform as well across such a broad spectrum of demands.
Maximizing Efficiency: Application Tips
Regardless of whether you choose synthetic or petroleum-based grease, proper maintenance is key:
- Clean Before Applying: Ensure tie rod ends are free from debris for maximum grease effectiveness.
- Use the Right Amount: Over-greasing can cause overheating; apply only as recommended.
- Inspect Regularly: Periodic checks help catch wear early and maintain consistent lubrication.

The Bottom Line
Both synthetic and petroleum-based greases deliver outstanding protection depending on your vehicle’s needs. Synthetic grease is often favored for its superior durability, temperature stability, and long-term performance, especially in demanding environments. Petroleum-based greases, however, provide reliable performance for general maintenance tasks and standard operating conditions. Understanding the differences will help you choose the right grease for your vehicle, ensuring smooth steering and long-lasting component life.
