FAQ

What is gear oil and where is it used?
Gear oil is a high-pressure lubricant used primarily in differentials, manual transmissions, transfer cases, and some types of steering systems. It’s essential for protecting gears, bearings, and clutches from wear and heat.

What types of gear oil do you carry?
We offer conventional, synthetic, and semi-synthetic gear oils in multiple weights (such as 75W-90, 80W-90, 85W-140, etc.), as well as specialty and limited-slip formulas to match your vehicle’s requirements.

How do I know which gear oil is right for my vehicle?
Always refer to your owner’s manual for viscosity (weight) and classification (API GL-4, GL-5, etc.) requirements. Our website filters and product descriptions also help you find the correct match.

Is gear oil different from engine oil or transmission fluid?
Yes. Gear oil is much thicker and designed for extreme pressure rather than high speeds or hydraulic performance. Never substitute gear oil with other types of automotive lubricants.

Can I use synthetic gear oil instead of conventional?
In most cases, yes—synthetic gear oils offer superior protection, thermal stability, and longer service intervals. Just ensure compatibility with your system and any manufacturer recommendations.

Do I need a friction modifier in my limited-slip differential?
Some limited-slip differentials require a friction modifier additive for quiet and proper clutch operation. We carry both gear oils with modifiers included and additives sold separately.

How often should I change my gear oil?
Service intervals vary by vehicle and use; typically, gear oil should be changed every 30,000–60,000 miles, or as specified in your maintenance schedule.

What if my gear oil arrives leaking or damaged?
Customer satisfaction is our priority. If your product arrives leaking or damaged, contact us within 7 days for a replacement, exchange, or refund.
