Advanced full synthetic gear oil is the pinnacle, designed not just to lubricate but to actively enhance performance and protection in high-stress environments like a vehicle's differential or manual transmission.
The Synthetic Advantage
What's synthetic oil? At its core, it's a lubricant engineered in a laboratory, rather than refined from crude oil. The molecules are designed for uniformity, which translates into superior performance characteristics. What's in synthetic oil? High-purity base stocks and advanced additive packages work together to deliver benefits conventional oils can't match. This includes better flow at low temperatures, preventing wear during cold starts, and greater resistance to evaporation and breakdown at high temperatures. This is critical for gear oil, which operates under immense shear forces and heat generated by meshing gears.
When considering the difference between synthetic blend and full synthetic oil, the distinction lies in the percentage of synthetic base stocks. Full synthetic, like Valvoline's advanced offering, is 100% synthetic. This purity means no compromises. It's the best choice for demanding applications where extreme temperatures or heavy loads are common.
This commitment to quality ensures that when you pour Valvoline Advanced Full Synthetic Gear Oil into your differential, you're not just topping off a fluid; you're investing in the long-term health and reliability of your vehicle's most hardworking components. Your engine, your story, deserves the best protection.
Gathering Your Tools and Prep for the Gear Oil Change
Before you even think about draining the old fluid, let's make sure you have everything ready. A gear oil change, especially using Valvoline Advanced Full Synthetic Gear Oil, is a straightforward DIY task if you're prepared. It’s about having the right tools and ensuring your vehicle is safely positioned.
What if you're unsure about the exact type of oil your vehicle needs? Always consult your owner's manual. It specifies the correct viscosity grade (like 75W-90 or 80W-140) and the required API service classification. This is crucial because using the wrong oil, or an oil that's not thick enough, can lead to premature wear. For instance, if you wondered which oil is thicker, 10W-30 or 10W-40, the 10W-40 is generally thicker at operating temperature. Similarly, gear oil grades have specific purposes.
Essential Gear for the Job
You'll need a few key items:
- Valvoline Advanced Full Synthetic Gear Oil (check your manual for the correct quantity and viscosity).
- A wrench or socket set to remove the drain and fill plugs.
- A fluid transfer pump or a funnel with a long, flexible tube to refill the differential.
- A drain pan capable of holding at least 5-6 quarts of fluid.
- Gloves and eye protection – gear oil can be messy and harsh.
- Shop rags or paper towels for cleaning.
- Wheel chocks for safety.
Prepare your workspace. Ensure the vehicle is parked on a level surface. If your vehicle has a limited-slip differential, ensure the Valvoline oil you purchased is compatible or contains the necessary friction modifiers. The owner's manual is your best friend here.
Consider it your personal automotive guide: safety is non-negotiable. If you're lifting the vehicle, use jack stands rated for its weight. Never rely solely on a jack. Once secured, place wheel chocks behind the wheels that remain on the ground to prevent any accidental rolling.
Step-by-Step: Draining, Filling with Valvoline Synthetic Gear Oil
Now that you're prepped, let's get your vehicle's differential filled with the superior protection of Valvoline Advanced Full Synthetic Gear Oil. This process focuses on the rear differential, but the principles apply similarly to front differentials or manual transmissions, always with reference to your specific vehicle's manual.
This is where the magic happens. You're about to replace old, potentially degraded fluid with a high-performance lubricant that's designed to withstand extreme conditions. It's a task that pays dividends in vehicle longevity and performance. The difference between a well-maintained drivetrain and one that's neglected often boils down to simple maintenance like this.
The Oil Change Procedure
- Locate Plugs: Find the drain plug (usually at the lowest point of the differential housing) and the fill plug (typically higher up on the side or rear of the housing).
- Drain Old Oil: Place your drain pan beneath the drain plug. Using the correct wrench, loosen and remove the drain plug. Let all the old fluid drain out completely. This might take several minutes.
- Clean and Replace Drain Plug: Once drained, clean the drain plug and its threads. Inspect it for any metal shavings, which could indicate excessive wear. Reinstall the drain plug and tighten it securely, but don't overtighten.
- Fill with New Oil: Position the drain pan under the fill plug. Remove the fill plug. Using your transfer pump or funnel, begin filling the differential with Valvoline Advanced Full Synthetic Gear Oil. Fill until the oil just begins to trickle out of the fill hole. This indicates the correct level has been reached.
- Replace Fill Plug: Clean the fill plug and its threads, then reinstall and tighten it securely.
A common misconception is that gear oil doesn't need changing as often as engine oil. However, gear oil endures incredible stress and heat, breaking down over time. Regular changes, especially when using a high-quality product like Valvoline Advanced Full Synthetic Gear Oil, are essential.
Don't rush the filling process. Using a pump is often cleaner and easier, especially if the fill plug is in an awkward spot. Ensure the oil is flowing smoothly and that you stop filling as soon as it reaches the fill plug level.
The unsung hero of your vehicle's health is the attention you give to its less glamorous, yet critical, components. This gear oil change is one such act of care.
Verification, Maintenance, and Troubleshooting
After completing the gear oil change with Valvoline Advanced Full Synthetic Gear Oil, a quick verification step ensures the job was done right and sets you up for optimal long-term performance. It's about peace of mind and proactive care.
What happens if you notice a leak after the change? Or what if your gears are suddenly louder? These are crucial questions that point to potential issues you need to address. Don't ignore early warning signs; they are your vehicle's way of communicating its needs.
Checking Your Work and Routine Care
Verification: After running the vehicle for a short drive (a few miles), re-check the fill and drain plugs for any signs of leakage. A small amount of oil residue is normal, but active dripping is not. Listen for any unusual noises from the differential during your test drive; smooth, quiet operation is the goal.
Routine Maintenance: Consult your owner's manual for the recommended interval for changing gear oil. This can vary significantly based on driving conditions (towing, heavy loads, stop-and-go traffic) and the type of vehicle. For many, a change every 30,000 to 60,000 miles is typical, but always verify. Using Valvoline Advanced Full Synthetic Gear Oil means you are providing the best possible protection, potentially allowing for longer intervals between changes compared to conventional oils, but never exceed manufacturer recommendations.
