• Vehicle Maintenance: Regular maintenance is crucial. A poorly maintained vehicle can suffer from reduced fuel efficiency. Things like dirty air filters, worn spark plugs, and underinflated tires can all negatively impact your MPG. Keeping your car in tip-top shape is important for optimal performance. Regularly changing your car's oil and filters, ensuring your tires are properly inflated, and addressing any maintenance issues promptly will help keep your RX300 running efficiently. A well-maintained engine is more efficient and burns fuel more effectively. Clogged air filters restrict airflow to the engine, causing it to work harder and use more fuel. Similarly, worn spark plugs can cause misfires, leading to decreased fuel efficiency. Underinflated tires increase rolling resistance, which means your engine has to work harder to move the car. If you take care of the car, the car will take care of you. Regular maintenance can save you money on fuel costs and extend the life of your vehicle. A well-maintained car is safer.

• Driving Conditions: City driving with frequent stop-and-go traffic will always be less fuel-efficient than highway driving. Also, driving in hilly terrain or in strong winds can reduce your MPG. The environmental conditions also play an important role. Driving conditions significantly impact fuel consumption. Stop-and-go city traffic, with frequent acceleration and braking, is a notorious gas guzzler. The engine constantly has to work harder. Highway driving is usually more fuel-efficient, as you can maintain a constant speed. This allows the engine to operate more efficiently. Weather conditions such as strong winds and hilly terrains also have a huge impact. Driving in adverse weather conditions, such as heavy rain or snow, can also affect fuel economy. Moreover, the weight of the car and the cargo also play an important role. Driving in the city will burn more gas. The terrain and weather conditions also play a big role in fuel consumption.

• Tire Pressure: Always check your tire pressure. Underinflated tires increase rolling resistance, which makes your engine work harder and burns more fuel. Maintaining the correct tire pressure is one of the easiest and most effective ways to improve your fuel efficiency. The recommended tire pressure for your RX300 can usually be found on a sticker inside the driver's side doorjamb or in your owner's manual. Be sure to check your tire pressure regularly, especially during seasonal changes, as the pressure can fluctuate with temperature. Maintaining the correct tire pressure can not only save you money on fuel but also improve your vehicle's handling and safety. Underinflated tires can also lead to uneven tire wear, which means you'll need to replace your tires sooner.

• Fuel Quality: Using a higher octane fuel than recommended by Lexus won't necessarily improve your fuel economy, and it can even be a waste of money. Stick to the fuel grade recommended in your owner's manual. Always use good quality fuel for your vehicle. Using higher octane fuel than recommended won't improve your fuel economy. Always follow the fuel type recommended by the manufacturer.
