What type of transmission fluid does the Hyundai Grand i10 use? How to identify the AT and MT versions based on the car's model year?

In Vietnam, the Hyundai Grand i10 is available with both a 4-speed automatic and a 5-speed manual transmission. These two types of transmissions have completely different operating principles and oil requirements.

The 4AT version uses ATF automatic transmission fluid. The 5MT version uses MTF manual transmission fluid with viscosity and standards suitable for the gears and synchronizers. It is not advisable to use the same type of fluid just because two cars share the Grand i10 name.

Quick answer

With the previous generation Grand i10 using a 4-speed automatic transmission, Hyundai's documentation states...DIAMOND ATF SP-III or SK ATF SP-III.

For the Grand i10 with a 5-speed manual transmission of the same generation, the reference requirements are:API GL-4, SAE 75W-85.

According to the GARTZ product catalog:

4AT Automated Version: ComparisonGARTZ ATF G4After confirming that the vehicle's specifications match the product description.

The 5MT manual transmission version requires GL-4 75W-85: see reference.GARTZ MT 75W85.

Newer generation vehicles from 2021 onwards: still available in 4AT and 5MT versions, but you need to check the oil specifications in the owner's manual or by VIN number before use.

Grand i10 lookup table by model year

Model year and version	Gearbox type	Standards to be checked	Gartz comparison product
Grand i10 2014–2020 AT version	4-speed automatic	Hyundai ATF SP-III according to vehicle documentation.	Gartz ATF G4 after full verification
Grand i10 2014–2020 MT version	5-speed manual transmission	API GL-4, SAE 75W-85	GARTZ MT 75W85
Grand i10 from 2021 onwards, AT version	4-speed automatic	Look up the vehicle registration number, VIN, and transmission code.	Compare with GARTZ ATF G4 to ensure the specifications match.
Grand i10 from 2021 onwards, MT version	5-speed manual transmission	Check the viscosity grade and API standard according to your vehicle.	GARTZ MT 75W85 if the vehicle requires GL-4 75W-85
Grand i10 imported or with a replaced gearbox	It may differ from domestically assembled vehicles.	Check the gearbox code directly.	Select after verification

The table above is for guidance only. The final conclusion must be based on the specific vehicle, especially for imported vehicles or those with replaced transmissions.

What transmission options are available for the Grand i10 in Vietnam?

According to Hyundai Thanh Cong's specifications document, the previous generation Grand i10 in Vietnam had two main configurations:

5-speed manual transmission, designated 5MT.

4-speed automatic transmission, designated 4AT.

In the new generation Grand i10 launched in 2021, Hyundai Thanh Cong continues to offer both of these options. Current Grand i10 specificationsIt still lists the 1.2MT and 1.2AT versions with either a 5MT or 4AT transmission.

Therefore, it's impossible to determine the type of oil simply by the name "Grand i10 1.2". It's necessary to know whether the car is an AT or MT version.

What type of oil does the Grand i10 4AT automatic transmission use?

Previous generation Grand i10

Hyundai Grand i10 Owner's ManualThe recommended fluid level for automatic transmissions is:

DIAMOND ATF SP-III or SK ATF SP-III

SP-III is the ATF standard commonly found in many older Hyundai and Kia 4-speed automatic transmissions. This is the important information for choosing the right oil, not the color of the oil or the general name "automatic transmission fluid".

The GARTZ ATF G4 is designed by GARTZ for 4-speed automatic transmissions and includes several Hyundai application codes such as A4CF1-2. Therefore, the product may be listed as a reference for the Grand i10 4AT, but garages need to double-check the transmission code and request the correct OEM code for their vehicle.

It should not be stated that GARTZ ATF G4 has been approved by Hyundai without corresponding certification documentation.

The new generation Grand i10 will be available from 2021.

According to Hyundai Thanh Cong's specifications, the new generation Grand i10 still uses a 4-speed automatic transmission. However, simply knowing "4AT" is not enough to definitively confirm the diesel version.

Before choosing GARTZ ATF G4, you need to check:

The owner's manual is for the specific model of vehicle.

VIN number.

Gearbox code.

Labels or information on the gearbox housing.

Repair history, including gearbox replacements, if any.

If the vehicle's documentation confirms that the standard or application code falls within the published GARTZ ATF G4 range, the new product is considered compliant for comparison.

What type of oil should be used in a Grand i10 5MT manual transmission?

For the previous generation Grand i10 1.0L or 1.2L manual transmission, the owner's manual stated:

Viscosity level:SAE 75W-85

Performance benchmarks:API GL-4

Reference capacity: approximately1.9–2.0 liters

Hyundai also announcedAPI GL-4, SAE 75W-85This oil is listed in the maintenance oil catalog for the Grand i10 manual transmission. However, the actual capacity when changing the oil may differ from the total capacity of the transmission; technicians need to follow the oil level check procedure.

GARTZ MT 75W85This product is designed for manual transmissions and is offered by GARTZ with a viscosity grade of 75W-85 and API GL-4 standard. This product can be used as a reference for the Grand i10 5MT if the vehicle specifications match.

Why doesn't the manual transmission Grand i10 use ATF G4?

ATF G4 is developed for automatic transmissions. ATF oil is involved in transmitting hydraulic pressure, controlling the clutch, and maintaining the friction characteristics of the automatic transmission.
