Which, of course, is modifying the car - NOT gaining better mileage by
simply adding high octane gasoline...

The next time your favorite "consumer advocate" from the local television
station or newspaper does a story on the oil companies and how they "gouge"
people by pushing unnecessary "plus" and high octane fuel......

.....remember this thread.

If the oil company executives are following this, I am sure they have come
up with several different new ways to reach into the pockets of gullible
car owners to improve the bottom line

 This is a very interesting and informative thread-as is the group here
as a whole. Here in S Tx. 87 octane is $.05 at a few independent
stores, the major chains are mostly in the $.12-2.17 range. At at least
95%, the difference between grades is a dime, so it really wouldn't take
a very big increase in mileage to be cost effective. The problem is that
such a small increase would be hard to accurately determine, given all
the variables affecting gas mileage. I would imagine that even the
temperature would affect octane requirements. In desert areas where it
may be 70 in the morning and 100+ in the afternoon, it may not be cost
effective on the way to work, and the opposite on the way home. The
funny thing is that there was a dime difference between grades when gas
was $.00, and also when it was $.00, but as the price was climbing
towards $..00 (about as high as it got here) people started buying 87
octane instead of 89 or 91, when it is actually a better deal as the
price increases. I have a company van and they use 87 octane, and the
only gas burner I have is a Ford Aspire, so do spend much on gas. Diesel
is another story tho-- got a couple and have some questions. since there
seem to be some pretty sharp gearheads in here, let me know if it is ok
to ask in this thread --or at all.     Larry

 No demand for the big octane = lower price.

Demonstrates the oil companies can charge what they want.
