Basically, addressing and dealing with high gas price does not necessarily mean you take costly measures beyond what is natural and normal. This means when gas prices were lower, there were a lot of things you did not mind or attend to, like:

Driving habits that uses more fuel when:

• suddenly accelerating and braking

• running engine and air-con is on while waiting for someone or parked
• revving the engine for no reason or before turning it off

• warming up the engine before driving off

Car Condition:

• make sure entire ignition system works properly
• fuel delivery, either carburettion or injection, is in top condition - fuel filters must be cleaned or replaced when necessary
• air filters must be clean so correct air and fuel mixture is achieved

• correct or recommended tire pressures in specified road conditions
• if possible or affordable, keep gasoline tanks topped off to minimize evaporation
• transmission must be in top shape so engine is not forced to work harder than necessary
• exhaust system must not have leaks or be noisy as driving could be different from normal or ideal way
• the engine must be in the best shape, no blow-bys, loose compression, oil or coolant leaks - if possible let it undergo a reliable engine analysis or test
• the battery and charging system should be in good condition so you do not keep revving to make sure of charging it

Others:

• short drives will mean engine is not in operating temperature, so demand for fuel will be more, compared to longer drives that bring the car to operating temperature
• relieve the car from unnecessary weight or load - the heavier the car is the more fuel it needs to work the engine
• plan your trip, if not, make sure you can make maximum use of the car in every trip or drive
• short-cuts could mean more traffic - that's fuel used without getting anywhere
• allow for more time to avoid rushing
• park car in cool shaded areas to minimize evaporation
• if parking spot is not sure to wherever you're going, opt for other cheaper means of conveyance
• learn on how calculate how many miles or kilometers per gallon or liter your car consumes - this helps on how you could drive your car economically
