ElantraClub - For Elantra Owners and Enthusiasts _ Elantra AD/MD/UD General _ MD 40 MPG Road Trip How to

Posted by: 13ABLtd Mar 23 2014, 12:13 AM

2013 Limited with Technology Package and automatic transmission. Car has a K&N drop-in air filter, otherwise 100% stock. Mileage is now just over 58,000.

I commute 98 miles one way 5 days a week. The highway speed limit is 75 mph and the secondary road speed limit is 65 mph. I pass through two towns, but no stoplights. I drive approximately 91 miles on the secondary road. I use the cruise control and the ECO mode is on. I use 87 octane with the 10% methanol, which is also oxygenated. Gasoline without methanol is not available where I live or drive. Driving the posted speed limits, I average 36.5 to 37.5mpg. I have achieved 39.5mpg, but that was driving at 55mph on the drive home in the 65 mph zones only. On occasion, I have achieved 38mpg. If I have a lot of wind, my mpg will drop to 33-35.

While I am disappointed that the mpg rating was inflated, I am happy with what I do get. I wish the fuel tank was a little bit bigger. My mpg numbers were determined by dividing miles driven by gallons of gas used. I have every last fuel receipt since I purchased the car, 6/09/2012, with 9 miles on the odometer.

Off Topic:
I have not had a single issue with the car. The OEM tires lasted 48,000 miles ( rotated every 6K ). Had the headliner clip replaced, per the recall.

mcgov51- How are you determining your mileage? Do the 2011 and 2012 Elantra 's have the same 12.8 gal fuel tank as the 2013? Using all 12.8 gallons: your 4 round trips are 496 miles, at 38.75 mpg. The 5 round trips are 620 miles, at 48.44 mpg. I don't doubt the 496; I've done it as well. But......620 miles?
