Lubricating grease cannot be replaced by lubricating oil, as they have different properties and chemical compositions, along with the following differences:
- When lubricating, oil flows around the mechanical components (due to its circulating lubrication properties).
- In contrast, grease remains in place and forms a "protective layer."
- Therefore, grease is used in locations where oil cannot be utilized, as oil will flow away.

Bearing grease.

I - For engine oil:
- All 300 series, 500 series and 700 series: Replace oil at first 5000km.
- For 300 series and 500 series using HINO genuine oil:
+ With normal operation condition, vehicles will replace engine oil every 20,000km
+ With hard operation condition, vehicles will replace engine oil every 15,000km or less depend on situation.
- For 700 series using HINO genuine oil:
+ With normal operation condition, vehicles will replace engine oil every 30,000km
+ With hard operation condition, vehicles will replace engine oil every 25,000km or less depend situation.
II. For TM oil and Differential oil:
- For 300 series, trucks will replace oil periodically every 30,000km
- For 500 series and 700 series, vehicles will replace oil at first 5000km. And trucks will replace oil every 30,000km
