The Daihatsu Hijet is a compact and versatile mini truck that has earned a reputation for reliability, efficiency, and practicality. While it comes well-equipped for everyday driving and business use, there are several ways to enhance its performance, fuel efficiency, and overall driving experience. By following expert advice, you can ensure that your Hijet operates at peak condition while maximizing longevity and value.

1. Regular Engine Maintenance

Keeping the engine in top condition is the foundation of performance. Routine oil changes, filter replacements, and timely inspections prevent wear and tear and ensure smooth operation. Use high-quality engine oil recommended by Daihatsu and replace the oil filter every time you change the oil. Clean air filters also improve airflow to the engine, enhancing both power and fuel efficiency.

2. Upgrade the Air Intake System

A simple modification like upgrading the air intake can increase engine efficiency. Installing a high-flow air filter or cold air intake system allows the engine to breathe better, improving combustion and overall power output. Ensure that any modifications are compatible with your Hijet model to maintain reliability and avoid warranty issues.

3. Maintain Optimal Tire Pressure and Alignment

Proper tire maintenance directly impacts fuel economy, handling, and performance. Check tire pressure regularly and keep it at the manufacturer’s recommended levels. Rotate the tires every 6,000 to 8,000 miles and ensure proper wheel alignment. This reduces uneven wear, improves traction, and enhances vehicle stability during driving.

4. Upgrade Suspension Components

Improving your suspension system can significantly enhance handling and load stability, especially when carrying cargo. Consider replacing worn-out shock absorbers, springs, or bushings with higher-quality components. Enhanced suspension not only provides a smoother ride but also reduces strain on other vehicle parts, increasing overall longevity.

5. Use High-Quality Fuel

Fuel quality plays a critical role in performance. Using premium or high-quality fuel ensures better combustion, reduces carbon buildup, and helps maintain engine health. Consistently low-quality fuel can lead to reduced power, higher fuel consumption, and long-term engine damage.

6. Optimize the Exhaust System

A well-maintained exhaust system improves engine efficiency by ensuring smooth exhaust flow. Inspect the muffler, catalytic converter, and pipes regularly for leaks or blockages. Upgrading to a performance exhaust system, when compatible, can improve airflow, reduce backpressure, and slightly increase horsepower while enhancing fuel efficiency.

7. Keep the Vehicle Light and Organized

The weight of your Hijet affects acceleration, fuel consumption, and braking performance. Avoid carrying unnecessary items and keep the cargo organized. If possible, invest in lightweight storage solutions and distribute the load evenly. A lighter vehicle is easier to handle and improves both acceleration and fuel economy.

Final Thoughts

Enhancing the Daihatsu Hijet performance doesn’t always require major modifications. By following these 7 expert tips, including regular engine maintenance, tire care, fuel optimization, and suspension improvements, you can maximize efficiency, power, and reliability. Proper care and thoughtful upgrades ensure that your Hijet remains a dependable partner for both business and personal use.
