How to Maintain Your 60,000-Mile Old Infiniti G25
Unofficially labeled a "budget-oriented" car, the Infiniti G25 has a lower base price compared to other luxury sedans. However, this doesn't mean it's not worth checking out—this vehicle comes standard with a smooth V-6 engine and has the same elegant yet sporty good looks as other Infiniti sedans. In terms of performance, the G25 passes the mark. Its acceleration is adequate, gear changes are quick and smooth, and its road noise is acceptable and never obnoxious. Those who have an Infiniti G25 have a great investment in their garage, so if you are able to make your car reach 60,000 miles, then you're in luck: you can make it last even longer with these tips.
The last time you replaced your Infiniti G25's air filter was 30,000 miles ago, so it's time to change it again now. Doing this increases your fuel mileage by 14 percent, which is helpful as your car gets older. In addition, it also helps prolong the engine's life because the air filter is responsible for trapping damaging dirt and debris that can cause internal damage to your engine components. If you neglect to do this, though, the filter will get clogged, which in turn can reduce air flow into the engine, and thus affect emission control systems of your car. This will cause an incorrect air-fuel mixture and ignition problems, which can then lead to serious issues with your car's performance.
- Replace the engine's coolant.
This is the first time you will be doing this task. You may not have even thought about this fluid, but engine coolant actually deteriorates over time. However, as your Infiniti G25 gets older, you will need to change it every 30,000 miles from hereon. But just because the coolant doesn't need to be changed for a while doesn't mean you'll forget about it until then. You will still need to get this checked by a professional to look out for acid buildup, rust, and other contaminants, as well as its resistance to freezing and boiling.
- Install a new in-cabin micro-filter.
The Infiniti G25's in-cabin micro-filter is responsible for cleaning the air that comes into your car's interior through the heating, ventilation, and air conditioning system. It catches dust, pollen, and other airborne material that can make you and your passengers feel uncomfortable while in the vehicle, especially if you have allergies or other respiratory problems. The Infiniti G25's owner's manual recommends that you replace this filter every 15,000 miles, but you may adjust this schedule depending on where you live and how often you drive. If you live in an urban area with poor quality or in a place with a desert climate where there's a lot of dust, then you will need to replace the filter as often as every 12,000 miles.
Aside from looking after the long-wear items and components, it is still important to inspect and replace the engine oil and filter and rotate your tires. You should also check the axle and suspension parts; the brake calipers, pads, and rotors; and the drive shaft boots if your Infiniti G25 has a four-wheel drive or an all-wheel drive.
