1. Drive smoother.
Have you ever ridden with someone who erratically alternates between aggressively speeding up and slowing down, then speeding up and slowing again? Besides being annoying to everyone in the car, it is also a huge drain on gasoline.
2. Reduce idling.
The last I checked, idling gets you zero miles per gallon. If you’re going to sit more than 20 seconds, you use less gas by shutting the car off and re-starting when you go. (You’re excused if the purpose of your idling is to warm up the car when it’s 20 below, as is often the case in our neck of the woods in January.)
3. Combine trips.
It’s a matter of planning and makes sense as well. One trip to three stores near the mall will use less gas than three trips – though most home plumbing projects require three trips to the same store with little you can do about it.
4. Keep tires properly inflated.
We’ve all heard this one, and it’s valid. Under-inflated tires can lower gas mileage by 0.3 percent for every one psi drop in pressure of all four tires. Properly inflated tires are safer and last longer. Is checking tires a routine part of your oil change regimen? It should be!
5. Use a premium synthetic oil.
During its circulation through the engine, motor oil serves to lubricate parts, keep the engine free of deposits, seal the piston rings and valves against leakage of combustion gases, and cool hot internal surfaces. Premium synthetic oils not only prevent excessive wear and deposit buildup, they are also more resistant to the kind of oxidation and deterioration at high temperatures that produces sludge and varnish. They are also easier to pump throughout the engine. All of these make the engine more inefficient, thus saves gas.
6. Keep engine interior clean.
Injectors can be very sensitive to fuel quality. Deposits on fuel injectors can inhibit fuel flow, causing erratic idle, poor acceleration and hard starting. Throttle plates and valve stems also need to be clean to operate properly. A professional fuel system cleaning will keep all these components clean.
