As a car owner, it’s important to understand which transmission fluid is appropriate for your vehicle. One question that often arises is whether Can I Use Dexron 4 Instead Of 2 or not.
All Dexron fluids are closely compatible. This means that you can use Dexron III or Dexron VI instead of Dexron 2. If you’re unable to find Dexron II, mixing Dexron III with your existing fluid in the power steering reservoir is possible without any problems.
As always, it’s best to follow your vehicle manufacturer’s guidelines for optimal performance and safety. Now take a look at these two popular transmission fluids in detail.
Can I Use Dexron 4 Instead Of 2? A Clear Insight!
While Dexron II and Dexron IV are both automatic transmission fluids, it’s important to note that they have different specifications. Dexron IV is a more advanced and improved formulation compared to Dexron II. While Dexron IV is backward compatible and can be used in vehicles that originally required Dexron II, the reverse is not true.
In general, it is recommended to follow the manufacturer’s specifications for your vehicle. Check your vehicle’s owner’s manual or consult with a professional mechanic to ensure that using Dexron IV instead of Dexron II is appropriate for your specific transmission.
What is Dexron 4?
Dexron 4 is a type of automatic transmission fluid (ATF) developed by General Motors (GM) for use in automatic transmissions. It is the successor to Dexron 3 and was first introduced in 2005. Dexron 4 is a synthetic fluid that is specifically designed to improve transmission efficiency and durability.
The formulation of Dexron 4 includes a range of high-quality base oils and advanced additives that work together to provide optimal performance and protection for the transmission. These additives include anti-wear agents, friction modifiers, and detergents that help to keep the transmission clean and prevent the buildup of harmful deposits.
One of the key benefits of Dexron 4 is its improved fluid stability and resistance to oxidation. This means that it lasts longer and provides better protection for transmission over time. Dexron 4 is also designed to work in a wide range of operating conditions, from extreme heat to extreme cold.
Dexron 4 is compatible with most GM automatic transmissions, as well as many other makes and models. However, it’s important to note that not all automatic transmissions are compatible with Dexron 4, so it’s essential to check the vehicle owner’s manual or consult with a qualified mechanic before using this type of fluid.
What is Dexron 2?
Dexron 2 is an automatic transmission fluid (ATF) that was developed by General Motors (GM) in the 1970s. It is a mineral-based fluid that is specifically designed for use in automatic transmissions that require a friction-modified ATF.
Dexron 2 is formulated to provide superior transmission protection and performance, with a range of additives that help to prevent wear and extend the life of the transmission. These additives include anti-wear agents, friction modifiers, and detergents that help to keep the transmission clean and prevent the buildup of harmful deposits.
One of the key benefits of Dexron 2 is its compatibility with a wide range of older GM vehicles, as well as many other makes and models. It is also designed to provide good performance in a variety of operating conditions, including extreme heat and cold.
However, it’s important to note that Dexron 2 has been superseded by newer ATF formulations, including Dexron 3, Dexron 4, and Dexron 6. While these newer fluids are designed to be backward compatible with older transmissions that require Dexron 2, it’s important to check the vehicle owner’s manual or consult with a qualified mechanic before using them.
This will ensure that you’re using the correct ATF for your specific vehicle, which is essential for optimal performance and longevity.
Dexron 2 vs 4: Comparison Table
Here is a comparison table for the specifications of Dexron 2 and Dexron 4:
| Specification | Dexron 2 | Dexron 4 |
|---|---|---|
| Base oil type | Mineral | Synthetic |
| Color | Red | Red |
| Flash point, °C | 195 | 226 |
| Pour point, °C | -45 | -51 |
| Viscosity index | 170 | 178 |
| Density, kg/L | 0.875 | 0.842 |
| Oxidation stability, hours | 50 | 100 |
| Compatibility | Compatible with older GM transmissions | Compatible with most GM and other makes/models transmissions |
| Applicable models | Older GM vehicles | GM vehicles manufactured after 2005 |
As you can see, Dexron 2 is a mineral-based fluid with a lower flash point and pour point than Dexron 4, while Dexron 4 is a synthetic fluid with higher oxidation stability and viscosity index. Dexron 2 is designed for older GM vehicles, while Dexron 4 is compatible with most GM and other makes/models transmissions manufactured after 2005.
It’s important to use the recommended fluid for your specific vehicle to ensure optimal performance and longevity of your transmission. If you’re unsure which fluid to use, consult with a qualified mechanic or refer to your vehicle owner’s manual for guidance.
Can you mix Dexron 2 and 4?
In general, it is not recommended to mix different types of automatic transmission fluids, such as Dexron II and Dexron IV. Mixing different formulations can compromise the performance and properties of the transmission fluid, potentially leading to issues like reduced lubrication, overheating, or transmission damage.
It is best to stick to one type of transmission fluid that meets the specifications recommended by the vehicle manufacturer. If you need to switch from Dexron II to Dexron IV, it’s advisable to perform a complete fluid flush to ensure that the new fluid is used exclusively and to prevent any compatibility issues.
Always consult your vehicle’s owner’s manual or seek advice from a professional mechanic for specific guidance on your particular vehicle.

FAQ’s
Here are some frequently asked queries that you may need to check.
Q: Can I use ATF IV instead of Dexron for toyota camry 2005 Model?
It ”probably” be ok, but if the manual recommends to use Dexron or Dexron II, its best to use it
Q: Any issue with Dexron IV for power steering?
No, but don’t use too old Dexron IV fluid. Try to use new one.
Final Word
So, now you know that you can use Dexron 4 instead of Dexron 2 but It’s best to avoid using it unless your vehicle’s owner’s manual recommends it. Always use the recommended fluid to ensure optimal performance and longevity of your transmission.
