I have an '04 Corolla & have had Corollas since '84. Have never put
anything except "regular" into their tanks. OTOH, I've never experimented
with a slightly higher octane to see if it made any difference re: MPG, but
then something tells me it wouldn't...

Vehicles with electronically controlled spark advance can benefit from
higher octane, but the benefit does not always outweigh the costs of the
higher octane fuel. I recommend that you try 3 or 4 tanks of premium, then
3 or 4 tanks of mid-grade, and then 3 or 4 tanks of regular. Monitor your
fuel economy and see if you can measure the difference. If you cannot tell,
then use the 87 octane.

Do you have any scientific studies that back your claim? Gasoline is
gasoline. The only thing that changes is the additives. And there are
only certain additives that they can add to make the winter formulation.

A bottle of Techron would be much cheaper than the extra cost of 3 tanks of
premium gasoline.

And using regular gasoline just as effective and much cheaper still.

Related subject - refresh my memory: With a modern vehicle like the ones
we're talking about, what causes knocking? The advice used to be "User
higher octane gas", but my mechanic said "No - it could mean your {missing
idea} has/is a problem". What's the idea I'm forgetting?

Anyway, he said moving to premium gas would stop the knocking, but it just
masks a problem that should be fixed. Solution: Drive twice a month with
the radio off, passengers bound and gagged, and listen to your car.

Gee, you left yourself way too open. I won't even try.

Did the mechanic say the knock-sensor or EGR valves? The knock sensor
senses knocking and retards timing.

And if the passengers are in-laws, make it at least once a week.

Yeah...probably one of those.

Don't remind me. My mother in law took only 30 seconds to get carsick,
sitting in the front seat. It reached the point where I had to learn a whole
new way of driving, by visualing a full wine glass on the hood. Can't spill
the wine or make the glass slide or tip. What a pain in the ass, trying to
switch from Mario Andretti mode to old fart mode.

No, it is a crock.

Use 87, it is all the motor needs, and the octane that comes with 89 is
wasted. Do not waste your money on added octane.

1995 Tercel. Bought it with 99,990 miles on it. Owner had used 87 Octane.
I NEVER use 87 Ocatane. Filled it with 89 and reset the trip meter. After
a few tanks of 89 Octane, did the calculations and came up with 36-38 MPG
combined driving.

Now, I usualyy don't use 89 Octane either. So the next few tanks were 93
Octane. After a few tanks came up with 44-46 MPG.

Figuring when I owned the car gas was ~$1.65/gallon for 87 and $1.75 for
93, I figure over the time I owned the car I SAVED $220 by using 93.

Your mileage may vary. The only car I ever had that has bucked this trend
is an '89 Mazda 626 I currently have as a winter beater, and it gets
better MPG with 89...

Do you have any real evidence that the name-brand gas gets better mileage?
