what is the difference between ATF Z1, ATF DW1?

same; but dexron 3 is best fluid,

Just let you know that they are the same. Honda ATF DW-1 is the replacement for their Z1 product. From the mid-’90s, Honda’s most prevalent transmission fluid was the ATF Z1.

ATF Z1 had decent features but was later discontinued because it exposed users to carcinogens and reproductive toxicants.

 

Different type of transmission fluids,

Z-1 and DW-1 are the recommended ATFs for Honda and Acura vehicles.

Z-1 is the older version, and

DW-1 is its synthetic upgrade. You can use DW-1 in vehicles that call for Z-1,

but you can’t use Z-1 in a DW-1 vehicle. Most Hyundai, Mitsubishi, and Kia vehicles call for SP ATFs.

Honda ATF-Z1 VS DW1 VS Dexron III

 

The drivetrain of any vehicle requires different fluids for proper workflow. Automatic transmission fluid (ATF) is one of the most important fluids for maintaining the transmission system performance.

ATF manages lubrication, maintains an optimum temperature, and establishes a connection between the transmission and the engine. Many critical operations of the transmission system rely on this fluid. Hence, selecting the right ATF is of utmost importance.

 

However, there are tons of different types of ATF available from many brands.

As a result, car owners often get confused about which ATF will be suitable for their vehicle.

-------------------------

## ATF-Z1 vs DW1 vs Dexron III ;;

 

# Honda ATF-Z1 Automatic Transmission Fluid,

 

Z1 automatic transmission fluid is the first original ATF from Honda.

Manufacturers used highly refined mineral oil as the base for creating this transmission oil.

 

The viscosity index of Z1 ATF is 215.5. The temperature in the Honda transmission system is generally higher. This transmission liquid reaches 7.64 cSt viscosity at 100°C. Meaning the viscosity doesn’t change much even with temperature shifts.

However, this fluid will freeze at -50°C.

 

Like other automatic transmission oils, the Z1 transmission fluid is red in color.

It becomes a darker brown with time and pollution.

For maintaining proper performance, you should change this oil every 30,000 to 35,000 km.

 

Honda ATF Z1 is suitable for all transmission systems manufactured by Honda before 2011. You can use it on both passenger cars and off-roading trucks. Other than Honda vehicles, you can also use this oil on the transmission that calls for Dexron ii transmission liquid.

 

;; Benefits ;;

Honda ATF-Z1 Automatic Transmission Fluid

 

Honda ATF Z1 contains many additives for providing better lubricating and cleansing features. For the thermal stability it possesses, you’ll be able to enjoy smooth gear change at both low and high temperatures.

 

The cleansing additives keep the fluid cleaner for longer and prevent dirt build-up.

As a result, the lifespan of the transmission also extends.

 

Moreover, this fluid has less oxidation rate. This means you don’t have to change the oil as frequently. Also, Z1 oil is less expensive than others in the market.

 

;;Cons;;

Z1 transmission oil was discontinued by Honda in 2011. This transmission liquid has too many friction modifiers that interfere with a smooth gear shift with time. Also, it exposed users to reproductive toxicants and carcinogens.

--------------------

# Honda ATF-DW1 Automatic Transmission Fluid

 

Honda DW1 is the ATF Z1 transmission fluid equivalent launched by Honda in 2011.

The Japanese company Idemitsu is the supplier of this transmission oil.

 

This fluid is made with a synthetic base that is more stable.

You’ll experience excellent fluidity in varying temperatures with this fluid.

 

DW1 has a lower viscosity than its predecessor.

This also features a lower viscosity of 6.83 cSt at 100°C.

As a result, you’ll get improved gas mileage and lubrication with this fluid.

 

Moreover, all the failings of Z1 have been removed in this transmission oil.

It doesn’t include any carcinogens.

 

It has replaced the original Z1 ATF in all vehicles manufactured after 2011.

You can also use it in transmission systems that call for Dexron iii. These two ATS’s share similarities in components, hence Dexron iii is known as the Honda ATF DW-1 equivalent.

 

Other than Dexron iii, you can also use it as an alternative for other Honda synthetic transmission oils such as CBD and ATX.

 

;Benefits;

Honda ATF-DW1 Automatic Transmission Fluid,

 

The main advantage of DW1 ATF is the synthetic base which adds more stability and durability to the liquid. This also increases fuel efficiency by reducing frictional losses.

 

It features high heat resistance. As a result, the viscosity stays almost the same even at different temperatures. And you can enjoy good performance consistently.

 

That’s not all, this fluid lubricates the transmission system’s components so well that a thick film is formed on them. Your transmission gets high-level protection from corrosion and wears for this oil film.

People who cover a lot of mileage frequently would definitely benefit from this ATF. The wear resistance and temperature retention capability increase the lifespan of the transmission. Therefore, you’ll have to change the oil less frequently and spend less on maintenance.

 

Another benefit of DW1 is that it’s reverse compatible with Z1 ATF. You can use DW1 in all the transmissions that call for Z1 transmission fluid without any worry.

 

;Cons;

The sole disadvantage of the Honda DW1 transmission liquid is the price. This ATF is rather expensive. So, using it can become a bit costly especially if you need to change transmission fluid frequently.

-------------

# Dexron III Transmission Fluid,

 

Dexron iii is a high-quality automatic transmission fluid manufactured for General Motors vehicles. This bright red and clear liquid has been produced keeping in mind the needs of the newer compact transmission system.

 

This is a 100% synthetic fluid combined with excellent additive packages.

It can be used in torque converters and gearboxes along with the transmission system.

This also features a viscosity of 7.9 cSt at 100°C and a viscosity index of 186.

 

You can use it for all General Motor transmission systems manufactured before 2005 and other ones that call for Dexron ii or Mercon fluids. Moreover, Ford, Isuzu, Holden, and several other older Japanese models support this transmission fluid.

 

;Benefits;

Dexron III Transmission Fluid,

 

One of the predominant advantages of Dexron iii is that it’s suitable for a wide variety of transmissions. It’s most appropriate with General Motor vehicles. Also, this ATF is compatible with the Honda DW1 transmission fluid.

 

It has excellent oil oxidation prevention capability. As a result, pollutants can not degrade the oil as quickly. Therefore, the fluid stays fresh for longer and the transmission offers peak performance.

 

Dexron iii also has superior friction durability that enables smooth shifting and longer transmission life.

Moreover, you get to enjoy an improved clutch pack and band capacity with this fluid. It’ll protect your system from bronze and copper corrosion.

 

Another thing you’ll love about this fluid is the higher operating temperature. Yes, Dexron iii won’t degrade under high temperatures like other ATF’s. So, you’ll need to replace the fluid less frequently. That’s not all, this ATF will give you an enhanced shift-changing experience even at lower temperatures.

 

;Cons;

Not compatible with the transmission systems of Mercedes Benz, BMW, ZF, Renk, and Voith.

 

Which Transmission Fluid Is the Best between Honda ATF-Z1, DW1 and Dexron III?

 

The main difference between Honda ATF Z1 and Honda DW1 is the base oil.

Z1 has a mineral base that is not really thermally stable. On the other hand,

DW1 has a high-quality synthetic base that has increased stability.

 

DW1 has improved sealing effectiveness, gear durability, and thermal stability. All these results in better drivability. Moreover, new additives provide enhanced antioxidant activities.

 

If you have to pick one based on compatibility, I’d say go for Dexron iii. Because this transmission oil is suitable for various transmissions from different companies.

But Honda Z1 and DW1 ATF are compatible with older models of General Motor vehicles.

 

Another thing to mention is that Z1 is not compatible with Dexron iii or DW1.

You can use DW1 in transmissions that require Z1, but not the other way around. However,

DW1 is compatible with Dexron iii.

 

If you consider replacement, Dexron iii excels in this criteria too.

It has a longer lifespan than the other two ATF’s.

You have to change Dexron iii after 40,000 to 60,000 miles whereas Honda transmission fluids need to be replaced within 21,000 miles.

 

Also, Honda Z1 oil does not work great in lower temperatures.

But DW1 and Dexron iii have thermal stability.

 

Lastly, you should keep in mind that the transmission liquid best for one vehicle may not be suitable for another. So, always use the transmission oil recommended by your manufacturer.
