Here are some great tips for getting better fuel efficiency with almost every vehicle:
1) Drive the speed limit. This is the single most difficult thing to do, for most people, and the best way to get GREAT fuel efficiency. By steadily accelerating and gradually stopping (when possible) while keeping to speed limits, you can gain upwards of 30% in MPG, especially if you are used to stomping on the accelerator. A lighter foot means a bigger wallet!
2) Use cruise control. As they say....slow and steady wins the race. Using cruise control can also save fuel by eliminating erratic driving behavior.
3) Change your oil regularly and use an additive, such as Opti-lube oil treatment (we are not affiliated with them, we just like their product)
4) Be sure tires are inflated to the recommended pressure. You may gain 1 to 2% in MPG with properly inflated tires.
5) Be sure that your oxygen sensors are clean (the outside...please do not remove the sensor).
6) Replace your spark plugs with split fire, or PULSE plugs. This burns the fuel you use more completely, reducing CO levels in the exhaust.
7) Insulate your exhaust from the engine block, to the first oxygen sensors. This causes the sensors to operate at optimum levels sooner and keeps them there, even in cold weather.
What comes out of the exhaust is exactly what goes into the engine. The same exact atoms are present before and after combustion...just in different forms.
Ambient air (outside air) goes into the engine through the intake. This includes NITROGEN (78%), Oxygen (21%) and Argon+Co2 (1%). Fuel goes into the engine through the injectors. All fuels except pure hydrogen are hydrocarbons. This means that the fuel is made up of hydrogen and carbon atoms. Since ONLY the hydrogen burns, the carbon is vented through the exhaust as Carbon Monoxide, or Carbon Dioxide. Carbon Dioxide is what we want to exhaust, since Carbon Monoxide is deadly and indicates that the engine is running poorly, exhausting unburned fuel in the process. The Nitrogen is exhausted as Nitrogen and Nitrogen Oxide (a poison). The hydrogen is exhausted as H2O (water).
Although the largest part of most combustion gases is relatively harmless nitrogen (N2), water vapor (H2O) and carbon dioxide (CO2) (except with hydrogen as fuel), a relatively small part of it is undesirable noxious or toxic substances, such as carbon monoxide (CO), hydrocarbons, nitrogen oxides (NOx), partly unburnt fuel, and particulate matter.
