the manual for my 93 DX hatch is recommending that i use an octane higher than 86. i want to know if putting 91 will help, hurt or affect the car/motor/ performance in any way. thanx.

 

nope. the more octate the better

 

Use middle grade, the DX motor's compression does not need high octane - couldn't hurt though...

 

just use 87. anything else would be a waste of $$.

 

where do you find octang 86?
but its only a honda, 87 is fine, its not like its worth anything..
honda motor, low compression = 87

 

it honestly doesnt matter.....unless u have like FI or a beamer or 2.0+ ltr. Like a high comp ratio engine would call for for higer octane. Depending on what engine you have.....what do you have??????

 

is 91 octane ok?

I hope so, that's as high as it gets around here

 

use 87

you dont need anymore.

 

bay area gas is f'ing expensive. i'd stay with the 87 until you get a motor i'd care more about...unless it's not a stock d16

That's it. We used to have 93 octane a few years ago, but they took it away

 

use 87 anything higher is a waste of money. You would only need higher octane if you advanced your timing, had nitrous/turbo/super, and/or raised your compression.
