use of higher octane gasoline
 

I have a 1999 Honda Accord LX six cylinder with about 31,000 miles on it. I
have always used unleaded gasoline 87 octane (manual says use 86 or higher)
and had no problems. However a friend of mine said I would get better
performance and mileage if I used premium grade higher octane gasoline.
Other than paying a higher price per gallon is there really any difference
in performance or mileage using higher octane fuel if the compression ratio
remains unchanged?

He's wrong.

Have him show us his degree in chemistry, and his certifications from
the auto engineering or petroleum industries. What? He doesn't have
any? Imagine that.

He's wrong.

In your case, there's no difference other than (a) you'll spend more
money, and (b) you'll actually get slightly *in*ferior gas mileage and
power due to the higher octane fuel's requirements for burning.

Do you know what octane is? Better yet, let's ask him. Does HE know
what octane is?

Octane is not a "power booster".

Hi,
Would you believe your friend's advice or the owner's manual?
Have money to burn? You said your car is running fine.

Apparently if you use the 93 oct gas, you get 10 extra hp from the new V6
240hp Honda engine, according to some Honda engineer. Not sure about better
mileage though. However, I haven't heard anything of this sort about the
older 200hp V6 engine. Personally, I'd stick with the 87 octane.

Cheers,

Pete

Ah, the net. Great source for random crap.

Other than this anonymous Honda engineer that no one has ever actually
seen or talked to, is there any other source for this? No, I didn't
think so.

And even if this were true, it would be true IF and ONLY IF the engine
control computer were designed specifically for this situation.

This guy's 99 Accord most definitely isn't designed for this.

Yup, it's pretty much a hearsay. I wouldn't bet my life on it, that's for
sure.

It may be smart enough to adjust timing - many ECUs can do it these days.

Didn't I say it only applied to the new V6 (2003 and up)? ;-)
