Running Premium Fuel w/ N/T?

[DSMOCTANE]

-I am working with a 99' Eclipse with the 420a engine. I have bolt-on's including a short-ram cold air intake and a full header and catback exhaust system. On my rebuilt engine, is it truly beneficial to run premium 93 fuel? I know the fuel gauges in the gs-t and gsx insist on only premium, but will higher octane give me much more power for a n/t? I also heard fellow mechanics speaking of higher octane resulting in more efficient fuel economy and more mpg. What do you guys think?

93 is more explosives then 87 right?

Go the opposite, and actually 85 would be more explosive since it has no alcohol in it.

On n/t models it says "unleaded fuel only", doesn't say "regular unleaded fuel only"

It's the same meaning since the word "Premimum" isn't listed - just worded different since the usage of "Premumin Unleaded Fuels' is actually rare, so why confuse the general public with two terms for the same grade of fuel along with they know that UNL is cheaper than PUNL fuels.

No. Octane is a hydrocarbon, which has 18 isomers. One of those isomers is 2,2,4-trimethylpentane (iso-octane). Iso-octane is what is used when they test the octane rating in fuel. However, since iso-octane is not the the most knock resistant fuel available, the octane rating can actually be higher than 100. If 2,2,3-trimethylpentane would be used in the fuel instead of 2,2,4-trimethylpentane, the octane rating would be higher than 100.

I'm not a chemist by any stretch of the imagination, I'm just trying to regurgitate what I have learned on my own and what I have been taught by my close friend (who is a chemist).

I hope this helps

Also, gusu is correct, other countries rate their fuel differently, so that has to be considered, but that does not make the info meaningless.

Skatershawn- The original quote was from howstuffworks.

You read much to far into that statement, I was simply making a play on your quote "Eighty-seven-octane gasoline is gasoline that contains 87-percent octane and 13-percent heptane ".
