Filters are vital to your car’s lifespan. Air filters clean dirt and dust from the engine, while fuel and oil filters trap sediment and debris. Be sure to follow your vehicle’s owner’s manual’s guidelines on when filters need to be replaced.

To prolong the lifespan of your car, be sure to check the fluids.

Warm Up and Cool Down

It’s not good for any engine to ‘cold start’ and ‘warm finish’. It’s not good for them to sit unused. It’s especially bad for four-wheel drive systems, such as the Lexus GX 460, to sit idle, but it’s also bad for any engine to ‘cold start’. A cold start is when you start your vehicle and immediately start driving. This kind of wear is responsible for roughly 70% of engine wear.

To prevent this, warm the engine. Starting your vehicle and allowing it to sit awhile before driving prevents strain on the engine, and can prolong the vehicle’s life. Allowing the engine to “cool off” after driving prevents the same wear.

Just like an athlete needs a warm up before a work out, and a cool down afterwards to keep their heart and muscles in top notch condition, your Lexus needs to warm and cool down after each drive, to keep the engine and gears from getting too worn. This can greatly prolong the car’s life span and thus add to the mileage.


While modern vehicles can monitor their own fuel levels and remind you when it’s time to fill the tank, it’s not good for your vehicle to run on low. Monitoring your fuel levels will reduce the wear on your vehicle and help add to its’ longevity.

Modern vehicles have gauges and lights to monitor their own fuel levels and alert when it’s low, but it’s not good for the engine to run on anything less than half a tank. When you notice your tank is to about a fourth full, fill it up. This way, debris and waste will stay out of the fuel filter, and your engine won’t have to work any harder than it needs to.

Drive as smoothly you can. Sudden, erratic acceleration and braking puts strain on your car, and stress on the inner machinery, wearing them out faster. Accelerate slowly, avoid driving at high speeds and accelerating quickly, especially when it’s very hot or very cold outside. The Lexus GX 460 is powerful, but cannot accelerate quickly. Don’t hold the wheel to an extreme left or right—this will damage the power-steering pump.
