* Variability: Fuel economy depends on a huge number of factors, including:
* Engine size and model: Different Hiace models had different engines, and the exact model you have will significantly affect fuel consumption.
* Driving habits: Aggressive driving, frequent acceleration and braking, and heavy loads all decrease fuel economy.
* Road conditions: City driving with lots of stop-and-go traffic uses more fuel than highway driving.
* Vehicle maintenance: Properly tuned engines and efficient tires improve fuel economy.
* LPG system: The type and efficiency of the LPG system also play a role.
How to find an estimate:
1. Look for specific model information: Try searching online using the exact model year, engine size, and "LPG fuel economy" or "LPG mileage." You might find data from owners or websites specializing in Hiace conversions.
2. Consult owner's manuals: Check the owner's manual for the specific van model. While it might not include LPG data, it may provide information about fuel economy for the gasoline engine.
3. Contact Toyota: Reach out to Toyota directly or a Toyota dealership. They may have some general information or resources for LPG conversions.
4. Talk to LPG conversion specialists: If your van has been converted to LPG, contact the company that performed the conversion. They may have data or estimates for vehicles they've worked on.
Remember that any figures you find are likely estimates. The best way to determine your actual fuel economy is to track your LPG usage and mileage over time.
