Fuel Saving Tips
If you do your own oil changes than you can select any oil you want. Some national stores as well allow you to select synthetic oil. Some synthetics are shown to increase MPG from 3-15% at different RPM ranges, reduce emissions, reduce wear, and give more HP/Tor. Also using oil rated with 20(100c) after the W can increase MPG. If you manual tells you to use specific oil, I would stick to it to keep warranty or research more to become more informed outside of warranty.
