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

Posted by: mcgov51 Sep 23 2013, 07:36 AM

I've said it before . . . with or without a K&N Air Filter and a fresh Mobile-1 oil change
the new 1.8 Elantra will easily achieve 40mpg on the non-stop, level highway at most
posted speeds. No doubt and IMHO the K&N will get you another 1-2mpg more than
what you would have gotten without it . . . according to my tests over the years.

The biggest factor with any of this is the condition and quality of your oil.
Then the efficiency of your spark plugs & wires and air filter.

For years I drove from point A to Point B and got 4 round trips (62 mi. one-way) on a full tank of gas.
Immed. after a fresh oil change I got 5 round trips on a full tank of gas . . . 124 mi. more. This would
last for about 2 wks then mpg would start to slowly decline.

And my claim about the K&N was qualified (to myself) in the same way. It is good for 1-2mpg.

I use Mobile-1 5W/20 in the winter and 5W/30 in the summer and I change it every 5-6K miles
AND never use anything but an OEM Filter . . . never.
