Your Lexus GS450h is a mid-sized luxury sedan that was launched in 1993. It is also designed as a performance sedan. Built with V8 engines, it is extremely fast and powerful. But of course, its big engine needs to be fed with more fuel in order for it to run. Not very practical, is it? You don't have to worry as there are many ways you can do to save on gas money. Here are some ways on how to optimize fuel efficiency with your Lexus GS450h.

Studies show that engine maintenance done regularly can reduce fuel consumption by an average of 4%. It can reach up to an astounding 40% percent if the components that directly impact fuel consumption are well-maintained, say the oxygen sensor. If the oxygen sensor is faulty, your car's computer will mistake it for lean fuel/air mixture and make the engine burn more fuel, therefore adding to the fuel consumption.

Do you have sports equipment in your trunk? If you are not going to use them for the day, you don't have to carry them around every time you are driving as they add weight to your car. Your car's power is just appropriate with its weight, so adding excess payload puts more strain on the engine. In order for the engine to be able to supply the power that is needed, it needs to burn more fuel. Same goes if you have ski or bike racks installed in your car. The racks add drag to your car, so if you are not using them, you might as well remove them.

High rolling resistance because of underinflated tires also make the vehicle heavier to move. This is why you should ensure that your tires are properly inflated to lessen fuel consumption. Misaligned and unbalanced wheels also add to the rolling resistance of your tires, so make sure that you keep your wheels aligned and balanced.

According to studies, practicing conservative driving habits increases fuel economy by 33%. Bad driving habits like speeding, accelerating rapidly, and braking suddenly have a huge effect on the fuel economy of your car. If you are keen on saving fuel, you should avoid these bad driving habits. Your car is equipped with cruise control, which can also help a lot when it comes to saving on fuel, so make use of it.

If you are going to run errands, do them in one go. Short trips consume more fuel as more fuel is required when starting a cold engine, so avoid doing it if you can. You can also plan your routes ahead to save on fuel. Familiarize yourself with the shortcuts in your area. You should also avoid traffic jams as idling also burns fuel. If you are not familiar with the place, it will be wise to get a map to avoid circling around and get to your destination as quickly as possible.
