Overview of engine and transmission options
The Optra, marketed in several regions as the Lacetti, offered a range of four-cylinder petrol engines paired with manual or automatic gearboxes. The most common configuration is the 1.6-liter engine, with other markets sometimes offering a 1.8-liter option. Fuel economy figures depend on the specific setup and driving conditions.
Below are typical estimates by configuration to help you gauge expected fuel use.
1.6-liter petrol engine with 5-speed manual
City: 27–29 mpg (8.7–8.1 L/100km)
Highway: 38–40 mpg (5.9–6.2 L/100km)
Combined: 32–34 mpg (7.1–7.5 L/100km)

These figures reflect typical valuations from markets where the Optra/Lacetti was sold and can vary across regions due to tuning, fuel quality, and testing standards. Real-world results will depend on maintenance, driving style, load, tire type, and climate.
Real-world considerations
In practice, several factors influence fuel economy for the 2005 Optra beyond the engine and transmission choice. Driving patterns, highway vs. city mix, and vehicle condition can swing efficiency noticeably. Lower rolling resistance tires, proper tire inflation, regular air filters, and timely maintenance all contribute to better fuel economy over the life of the car.
Markets also show some variation in official ratings versus owner-reported figures, so consider both the published estimates and your own driving experiences when evaluating fuel costs.
What to know when buying or maintaining
If you’re shopping for a used 2005 Optra, ask for service history, especially regarding the ignition system, fuel injectors, and oxygen sensors, as these can affect efficiency. A well-tuned engine with clean filters and fresh fluids tends to achieve the higher end of the mpg range for its configuration.
Summary
The 2005 Chevy Optra’s fuel consumption varies by engine and transmission, with the 1.6-liter manual typically delivering the best economy among common configurations. Expect roughly 25–34 mpg (US) or about 7–9 L/100km in mixed driving, with automatic transmissions generally closer to the lower end of that range. Real-world results depend on driving conditions and vehicle maintenance.
In short, for most buyers the Optra offers competitive fuel efficiency for its era, especially in the 1.6-liter manual setup, but exact numbers will depend on the specific market and configuration.
