The Hino 268 is one of the most dependable medium-duty commercial trucks on the road, widely used for delivery, towing, freight hauling, landscaping, and fleet operations. Powered by the durable Hino J08E diesel engine, the Hino 268 is designed for heavy-duty performance, long service life, and fuel efficiency.
Using the correct engine oil is essential for protecting turbocharged diesel components, reducing wear, preventing sludge buildup, and maximizing engine longevity. Choosing the proper oil viscosity and following recommended maintenance intervals can help your Hino truck deliver reliable performance for hundreds of thousands of miles.
Hino 268 Oil Type
The recommended oil type for the Hino 268 is SAE 10W-30 heavy-duty diesel engine oil that meets current diesel engine standards such as API CK-4 or higher. In colder climates, some operators may also use SAE 5W-40 full synthetic diesel oil for improved cold-start protection.
Because the Hino 268 uses a turbocharged diesel engine, premium heavy-duty oil is critical for controlling soot buildup, reducing turbo wear, and protecting internal engine components under high-load conditions.
Best Choice: SAE 10W-30 Full Synthetic Heavy-Duty Diesel Oil provides excellent protection, fuel economy, and long-term durability for Hino 268 trucks.
Hino 268 Oil Capacity
The oil capacity of the Hino 268 depends slightly on engine configuration, filter size, and model year. Most Hino 268 trucks equipped with the J08E diesel engine require approximately 22 to 24 quarts of oil with a filter replacement.
Important: Always verify oil level after refilling and running the engine. Large diesel engines may require slight adjustments depending on filter size and complete drainage.
