When do you change gear oil of a Suzuki Alto?

Gear oil in a Suzuki Alto should typically be changed every 30,000 to 60,000 kilometers, or as specified in the owner's manual. It's important to check the oil condition regularly and replace it if it appears dirty or has a burnt smell. Additionally, if you notice shifting issues or unusual noises from the transmission, a gear oil change may be necessary sooner. Always refer to your vehicle's manual for specific recommendations.
