I mean, since it gets better gas mileage, i would see taht as a plus... but if it costs so much more to run, are you really saving anything?
That is one of those "your mileage may vary" type questions. From my personal experience so far, I say yes. I figure if it can increase my MPG, it must also be doing a heck of a job protecting engine parts from excessive wear too...
