Gartz MT 75W85 – Which type of manual transmission fluid should be used for Hyundai, Kia, and Toyota vehicles?

What is 75W85 manual transmission fluid?

75W85 oil is a manual transmission fluid, typically meeting GL-4 standards, used for:

Synchronized manual transmission (synchronized gearbox)

front-wheel drive gearbox

mainstream car models

This type of oil is designed to:

gear protection

Synchronization support

helps to shift gears more smoothly.

Unlike gear oil (GL-5), GL-4 oil has a suitable friction coefficient for precise synchronized operation.

When should I change the transmission fluid in a manual transmission?

You should check if your vehicle shows any of the following signs:

difficult to shift gears

The number is stuck.

Shifting gears feels "stuck".

The car has driven over 40,000 – 60,000 km without an oil change.

This is a sign that the oil has lost its ability to support synchronization.

Reasons why manual transmission cars have difficulty shifting gears.

In reality, in Vietnam:

Oil degrades over time.

Using the wrong standard (using GL-5 instead of GL-4)

not changing the oil regularly

Then:

The synchronizer is performing poorly.

incorrect friction

The gears are difficult to mesh.

Consequence:

into heavy gear

beeping sound when shifting gears

synchronizer wear

Which vehicles can Gartz MT 75W85 be used for?

Gartz MT 75W85 is suitable for:

Hyundai, Kia manual transmission

Toyota manual transmission

Mitsubishi manual transmission

Nissan manual transmission

Vehicles using GL-4 75W85 oil

This is a very popular group of vehicles in Vietnam.

Why do manual transmissions still need the correct oil?

Many people think:

Manual transmissions don't need to worry about oil.

But the reality is:

Synchronization depends on friction.

Gears need a protective layer of oil.

If you use the wrong oil:

enter hard number

noise when shifting gears

synchronizer wear
