Get Mitasu ATF WS Synthetic Tech MJ331-4 in Kenya

Mitasu is a renowned Japanese lubricant brand known for manufacturing high-performance oils and fluids for modern vehicles. One of their flagship transmission fluids is the Mitasu ATF WS Synthetic Tech MJ331-4 — a fully synthetic automatic transmission fluid specifically formulated to meet and exceed the requirements of Toyota WS (World Standard) automatic transmissions.

If you own a Toyota, Lexus, or Scion manufactured after 2004, chances are this is the exact type of ATF your vehicle needs. Let’s break down what makes this product special, and why it’s trusted by both mechanics and car owners globally.

2️⃣ What is ATF WS? 💧

“ATF WS” stands for Automatic Transmission Fluid – World Standard. It’s a special transmission fluid developed by Toyota for their modern automatic gearboxes, which demand:

✅ Superior heat resistance
✅ Long service intervals
✅ Smooth gear shifting
✅ Improved fuel efficiency

Mitasu’s MJ331-4 is designed as a high-performance equivalent to genuine Toyota WS fluid — but with enhanced synthetic technology that provides better protection, performance, and durability.

3️⃣ Key Features of Mitasu ATF WS Synthetic Tech MJ331-4 ⚙️

Here’s what makes this fluid stand out:

✅ Fully Synthetic Formulation
Unlike conventional or semi-synthetic ATFs, this is a fully synthetic fluid, meaning it’s designed to handle higher temperatures, longer drain intervals, and extreme driving conditions without breaking down.

✅ Meets Toyota WS Specifications
This fluid meets and exceeds Toyota’s stringent WS specification (JWS 3324), ensuring full compatibility with vehicles requiring WS fluid.

✅ Low Viscosity for Fuel Efficiency
Mitasu ATF WS is a low-viscosity fluid, which helps reduce friction inside the transmission, improving fuel efficiency and reducing power loss.

✅ Exceptional Thermal Stability
Whether you’re driving in extreme heat or cold, this ATF resists viscosity breakdown — meaning it stays stable even under heavy loads.

✅ Enhanced Anti-Wear Protection
The fluid is fortified with anti-wear additives to reduce internal gearbox wear, extending the life of your transmission.

✅ Prevents Sludge & Varnish Build-Up
Mitasu’s advanced additive package resists the formation of sludge, varnish, and deposits — keeping your transmission clean and efficient.

✅ Smooth Shifting Performance
Whether you’re driving in city traffic or cruising on highways, this ATF ensures buttery-smooth gear shifts for enhanced driving comfort.

4️⃣ Applications: Where to Use Mitasu ATF WS MJ331-4 🚗

Mitasu ATF WS is perfectly suited for:

✅ Toyota vehicles (2004 and newer)
✅ Lexus vehicles (2004 and newer)
✅ Scion vehicles
✅ Hybrid vehicles with E-CVT transmissions requiring WS fluid
✅ Cars fitted with Aisin automatic transmissions (used widely across Toyota and Lexus)

It is especially recommended for popular models like:

🚙 Toyota Camry, Corolla, RAV4, Prado, Land Cruiser, Hilux
🚙 Lexus RX, ES, GX, LX
🚙 Scion tC, xB, xD

5️⃣ Benefits of Using Mitasu ATF WS Synthetic Tech 🌟

1. Longer Transmission Life 🛡️

This fluid minimizes wear and tear inside your gearbox, meaning fewer expensive repairs and longer transmission lifespan.

2. Superior Oxidation Resistance 🔥

Oxidation (fluid degradation due to heat) is a common cause of ATF failure. Mitasu’s synthetic blend resists this, ensuring fluid lasts longer.

3. Improved Fuel Economy ⛽

The low viscosity reduces drag within the transmission, helping your engine work less — saving fuel over time.

4. Smoother Driving Experience 🚗

Ever felt jerky or delayed shifts? Old or incompatible fluid is often the cause. Mitasu’s optimized friction properties ensure shifts remain silky smooth.

5. Cold Weather Performance ❄️

This ATF flows easily even in freezing temperatures, ensuring no sluggish shifts during cold starts.

6. Compatibility with Modern Electronics 💻

Modern transmissions rely heavily on electronic solenoids and sensors. This fluid’s precise formulation ensures clean operation of those sensitive components.

6️⃣ How to Know It’s Time to Change Your ATF ⚠️

Even the best ATF doesn’t last forever. Look out for these signs:

🔧 Rough or Delayed Shifts
If your gears take longer to engage, your fluid might be worn or contaminated.

🔧 Transmission Overheating Warning
Old fluid loses its cooling ability — overheating damages the transmission.

🔧 Dark or Burnt Fluid
Healthy ATF should be clean and reddish. Dark, dirty, or burnt-smelling fluid means it’s time for a change.

🔧 Shuddering or Vibrations
Dirty or incompatible ATF can cause torque converter shudder — replacing fluid usually solves this.

7️⃣ How Often Should You Change Mitasu ATF WS? ⏱️

Toyota recommends changing WS fluid at:

✅ Every 60,000 – 100,000 km under normal driving.
✅ Every 40,000 – 60,000 km if towing or driving in severe conditions.

If in doubt, follow the severe service interval — fluid is cheaper than a new transmission!

8️⃣ Mitasu vs Genuine Toyota ATF WS: Which One? 🤔

This is a common question — and here’s the honest answer:

✅ Mitasu ATF WS meets and exceeds the same performance standards as Toyota Genuine ATF WS.
✅ Mitasu offers better thermal stability, oxidation resistance, and extended drain intervals due to its enhanced synthetic formulation.
✅ Mitasu ATF is often more cost-effective than dealership fluid.

In short: Mitasu ATF WS is a perfect substitute for genuine Toyota fluid — with added performance benefits.

9️⃣ Steps for Changing ATF Using Mitasu WS 💡

1. Lift vehicle and drain old fluid.
2. Remove transmission pan (if necessary) and clean magnet/filter.
3. Reinstall pan and refill with Mitasu ATF WS.
4. Run engine, cycle through gears, then check level.
5. Top up if needed, following dipstick markings or check plug procedure.
6. Test drive and recheck fluid after cooling down.
