👀❗️Why Changing Your Differential Oil Is Important ❗️👀

Your vehicle’s differential works hard every time you drive, transferring power to the wheels and allowing them to turn at different speeds when cornering.

Differential oil (diff oil) lubricates and protects the gears and bearings inside the differential. Over time, this oil can break down and become contaminated with metal particles, dirt and moisture, reducing its ability to properly protect these components.

What Happens If You Don’t Change Your Diff Oil?

Old or contaminated diff oil can lead to:

* Increased friction and heat
* Premature bearing and gear wear
* Whining, humming or grinding noises
* Damage to internal differential components
* In severe cases, complete differential failure — resulting in a costly repair or replacement

Vehicles that tow, carry heavy loads, travel off-road or regularly encounter water and mud can place even greater stress on their differentials and may require more frequent servicing.

A Small Service Can Prevent a Big Repair!

Changing your differential oil is simple preventative maintenance that can help extend the life of your drivetrain, reduce unnecessary wear and save you from expensive repairs down the track.

Not sure when your diff oils were last changed? Ask us to check them at your next service.

Finally 🙌🏼 We now do mapping on vehicles & small trucks!

🚗💨 Unlock Your Vehicle’s True Potential with ECU Remapping! 💨🚗

Did you know your vehicle’s engine is often programmed with conservative factory settings? An ECU remap optimises your engine’s software to help it perform at its best.

✅ Benefits of Remapping:
🔧 Increased power and torque
⛽ Improved fuel economy (when driven sensibly)
🚙 Smoother acceleration and throttle response
🏞️ Better towing performance
💪 More enjoyable driving experience

Whether you drive a car, 4WD, ute, truck, petrol or diesel, a professionally tuned remap can make a noticeable difference.

At RTJ Mechanical & Small Engine Repairs, we use quality tuning solutions tailored to your vehicle—no generic “one size fits all” tunes.
