Why Compare?

The main difference between Dexron 3 and Dexron 6 is that Dexron 3 is a semi-synthetic fluid whereas Dexron 6 is fully synthetic fluid. The main benefit of Dexron 3 is that it provides better cooling properties, which means it will help your engine to run more efficiently and provide a cooler-running engine.

Dexron-3 and Dexron-6 are both under the same trade name for a group of technical specifications of Automatic Transmission Fluid (ATF) created by General Motors (GM). This series of oil is made with a less reactive, more stable hydrocracked oil base that is very less prone to make contact with heat or friction.

But to mention the biggest difference between Dexron-3 and 6 is that of viscosity. Dexron-6 is much thinner. With the less updated base, Dex-3 provides less shelf life than 6. The thickness has been decreased up to 20% which is not at all a number to overlook. Here are a short description of these two completely distinct oil types yet under the same name.

Main Features of Dexron-3

Better Friction Stability

Compared with its previous rival ancestors Dex-II, Dexron-3 has more ability to stay less reactive to excessive friction. We all know that power never dies, it transforms from one to another. When fuel meets friction and friction meets heat it can lead to horrible accidents where life can be on sale. Keeping these all in mind, oil manufacturers are modifying their oils up to maximum optimization.

Oxidation Stability

A heavily used vehicle is always at the risk of being a casualty of high-temperature exposure. Fuel is a good source of the explosion. If heat makes its way to a massive amount of compressed natural gas (CNG) the result can literally create the same impact like an atomic bomb. So the nullification of heat reactivity and increased stability is definitely a life savior.

Better Material Compatibility

The compartment that the oil stays in is a different kind of concern in itself. The inner wall of the oil tank must be as less reactive as possible.

Low-Temperature Fluidity

Natural gas in a compressed liquid state often gets frozen and loses its natural density due to low temperature. Dex-3 has been designed to overcome this obstacle.

Limitations of Dexron-3.

We are looking for an oil that will pay off in the long run. But with Dex-3, it is quite doubtful where one often has to empty their pocket over synthetic fuel. Fuel with easy flowing qualities is one of the main concerns that will soothe the engine. With a rather thicker consistency, dex 3 has failed to assure that.

Main Features of Dexron-6

Improved oxidation

With the updated form of increased oxidation, Dex-6 assures the maximum fewer chances of avoiding fatal accidents.

Provides Extra Protection

Shear stability with effortless oil fluidity provides long mechanical life of the inner parts of the engine. With less friction and resistance it is a cakewalk while driving with Dex-6

Anti Wear Protection

Dexron-6 doesn’t lump in places creating a mess of its own to take care of. The thinner texture gives it a running and easy flow that doesn’t react with parts carrying themselves. Thus avoiding rust and securing a clean smooth interior.

Anti Foam Control

With the unfriendly road surface, oil tanks often feel a massive amount of juggling that results in an excessive amount of unwanted foam. Here in Dex-6, no matter the road condition the oil stays absolutely free of foam.

Low-Temperature Fluidity

With spontaneous fluency even in the low-temperature Dex-6 is an ultimate all-rounder.

Which to Pick and Why?

Well, it is safe to say that not only does Dexron-6 exceed the previous models of oil of the same series but also it is an automatic transmission fuel with longer shelf life. Dexron-6 has been serving as an ultimate solution right after it was first introduced and since then there was no turning back.

In our everyday busy life we can’t put our stamina worrying over the fuel we use for riding. If you are a person that is fond of high performances definitely go for Dexron-6. With this top-notch, synthetic, automatic transmission oil there is nothing that will go wrong.

Can Dexron-6 be used instead of Dexron-3?

Answer- You will be happy to know that Dexron-6 can be used in any proportion even for vehicles from an earlier era. Dexron-6 in one word is compatible with any other former version of the DEXRON series for its outstanding quality of automatic transmission despite the environment.

Wrapping Things Up!

I think it is pretty clear in front of our eyes with all the details laid that Dexron-6 has won the battle by a huge margin. There are no second doubts over whether it will pay off or not. Once bought and it will offer a long run. Where Dexron-3 is just an ordinary oil fuel with average performance, Dexron-6 easily stands out from the rest of its previous ancestor versions.

With the updated modification and edition of the automatic transmission system, Dexron-6 wins the title of the ultimate synthetic high-performance oil by GM.


No matter the road condition or weather, with Dexron-6 you don’t have to worry about your safety or your cars. With the optimized features to their maximum utilization, Dexron-6 will meet and exceed your expectations with rather a friendly budget. So, if you are searching for an all-rounder safety guard, fuel oil, or healer for engine parts go for Dexron-6 by DEXRON.

Frequently Asked Questions (FAQ)

Can I put dexron VI instead DEXRON III?
Yes, you can put Dexron VI instead of DEXRON III in your car. Dexron VI is a newer and better formulation of the DEXRON fluid, so it will work great in your car.

What is dexron VI compatible with?
Dexron VI is a type of transmission fluid that is compatible with many different types of vehicles. It is designed to work with both automatic and manual transmissions and can be used in various applications. Dexron VI is also compatible with a number of different types of fluids, making it a versatile option for many drivers.

DEXRON 3 is an improved version of the original DEXRON automatic transmission fluid. It was developed to provide better protection against wear and corrosion and to improve shifting quality. DEXRON 3 is not compatible with vehicles that require the original DEXRON fluid.
Yes, DEXRON 6 is backward compatible with all previous versions of the DEXRON specification. This means that any transmission fluid that meets the DEXRON 6 specification can be used in place of a DEXRON 3, 4, or 5 fluid. Additionally, DEXRON 6 fluids can be used in transmissions that require any of these older specifications.
