Saturn Aura Real World MPG



  • CWR 64 - How many miles on your 4 banger? If your under 5000, you'll just have to be ticked off for a while. After 5000 it starts to get better and will reach it's potential after 8000 to 1000 miles.
    Oh yea, You'll need to pump up those tires to at least 35front 34rear to get best mileage. 30 is like running on a flat as far as I am concerned. I run 37 front 35 rear when loaded and on a trip. I get 30+ average on the highway at 80 MPH with my 3.6L XR
  • Sorry, Stingy Mode is only available for McCain/Palin supporters. Liberals have to buy premium gas and get under 20 MPG. :D

    US EPA rates 4 cyl Aura as 22 City and 33 hwy. US EPA rating is done in a lab on a dyno so is pretty optimistic and that's why few if any get the posted rates. 6 cyl is 17 City/26 hwy. In Real World everyday driving, and with low drag coating on ours, a 4 cyl Aura gets better mileage than the posted EPA rating for a Smart car! Our Aura gets 30 City/45 Hwy @ 60 mph with no load) verified by OBDII reader Scan Guage II.

    I drive easy all the time. My 4cyl gets 31 highway, 21 city, using mid-octane gas, mileage calculated by me. It has 15K miles on it now. I'm not happy with this mileage, but now Saturn is gone and I doubt anyone is reading this blog anymore anyway. If I drive the interstate at more than 60-65mph (even on cruise control), the highway mileage drops like a rock.

    I apologize for your frustrations. I hope this information is beneficial to you:
    The best fuel economy possible is the direct result of proper maintenance and good driving habits. Listed below are GM's recommendations to achieve the best mileage possible. The first group are things to consider for your vehicle, while the second are tips relating to your driving habits. One of the major contributors to poor fuel economy are under inflated tires. Tires low with pressure create drag that the vehicle’s powertrain must overcome, wasting dollars in fuel. Always keep your tires inflated to the proper pressure as shown on the vehicle placard. This not only serves to increase gas mileage but cuts down on tire wear, further decreasing your costs per mile.A vehicle that has a dirty air filter can’t efficiently draw air into the engine. This restriction forces the engine to expend energy to "breathe" wasting fuel in the process. Change recommendations are found in your vehicle Owner’s Manual. Always use the proper viscosity oil in your engine. Oil that has a higher than required viscosity will create more drag on the internal components of the engine causing more work for it, especially when cold. Each Owner’s Manual contains information on the proper type of oil for your vehicle. Look for the "starburst" symbol on the front of the bottle, and the SM rating on the API circle on the back label. If you are in doubt, stop by your dealer for an oil change, and any other services required. Most current GM vehicles are equipped with oil life monitors to further assist on the "when" to change your oil. (aveo/Wave/Optra/Epica currently do not have oil life monitors).
    Note: GM Vehicles DO NOT require additional engine oil additives. Some additives may cause harmful effects to the internal seals and additionally void the terms of your vehicles New Car Warranty. Purchasing higher than required octane fuel is a waste of money. Using higher octane fuels in a vehicle that only required regular unleaded fuel will neither increase performance nor improve gas mileage. In all cases refer to your owner’s manual and ONLY use the octane rated fuel recommended for your vehicle. Even though current GM vehicles have 100,000 mi (160,000 km) service intervals for spark plugs if your vehicle is at that point in its life, have the spark plugs changed to assure proper running and continued efficient, trouble free operation. Avoid quick/full throttle acceleration from a standstill in town and high cruising speeds on the interstates. While the optimum MPG for highway cruising speed varies from vehicle to vehicle, faster is almost always worse. If your vehicle is equipped with a Driver Information Center that displays Instant Fuel Economy, select that readout and vary your cruising speed while on the highway. The display will change continuously with uphill and downhill sections but you should quickly be able to identify on level ground the speed range that your vehicle does the best in. Avoid leaving unnecessary items in your trunk. It takes power to move increased weight and that means more gasoline consumption and reduced performance. While the change may be slight, multiplied by thousands of miles, it all adds up. Your vehicle uses much more fuel when the engine is cold. This is especially true in the winter months when the engine will take the longest to warm up. Combine errands or trips so that the vehicle only needs to warm up once to encompass many different stops.
