higher grade equals higher mpgs?
if true i might have to try it out..
I don't know if it'll work on all cars. Try it on yours, then do the math. I am sure you'll get a few more miles on a tank, then you can see if the cost savings is worth it. Remember, Premium in the V6 will generate a little more power too....if that's worth anything to you.
Also, this isn't true for all cars. Our 97 Max SE is a AT, and it pretty much gets 23-24MPG in city whether we use 87 or 91. However, the engine pings a bit (almost 200K miles, she's tired) more on lower octanes when loaded up, so we try and keep at least 89 in that car...just depends on gas prices and my mood.
