Marketting. When trying to avoid gas guzzler taxes and the marketteers are 
demanding the highest possible MPG, it makes a difference. Believe the EPA 
got really mad at some in the 1970's when test cars showed up with 
synthetics not provided on the line.

Now 1 mpg on a 20 mpg car over 5,000 miles is a 12 gallon difference. $24 
today. Hadn't thought of it that way before but with the price difference 
narrowing and gas going up, it probably makes sense (why am trying now) but 
will probably go through the rest of my dino oil before switching.
