We'll.... I went fer a flat road drive in my 32MPG Accent, specifically to chase the 70MPG goal. Didn't think I could even get 60MPG..... even less. & I didn't. But, it was even worse than I thought it would be... only 52MPG. That was only 4-6 MPG more than my more general traffic & terrain driving last summer, when two tanks turned up 47+ & 48+ MPG. After 2 days, I checked my tire pressures, which I most often inflate to 40PSI. Three tires were 38PSI, but one was under 30PSI. So THAT may have had a lowering effect on MPG. Do you think one low tire could have lost 5 MPG? If I had used 87 octane ethanol-free gas (E0), THAT would have helped raise MPG. Four of my cars, normally gain 8% to 7% MPG, when burning E0, vs. E10. However, the Accent usually only gains 5% MPG over E10. Also, I may have been driving too slowly. More recent engine designs dote on low rpms to gain MPG. Both our 2013 & 2016 Elantras really pour out high MPG, when driving at 1500rpms, even lower. But our 2008 Accent, based on the 2006 Accent (even further back?) may want a slightly higher rpm. I don't know, if that is true.
Anyhow, the Accent, which I've been proud to drive in general country driving, didn't deliver what I hoped would have been 55MPG to 60MPG.
