Default RSX Base 03 still knocks with 87 octane gas

Hi,

I've read the posts about how it's unnecessary to user higher octane gas
than what the manual recommends. So, as my manual instructs, I've been
using 87 octane in my 2003 Base RSX. However I still hear a slight knocking
when i'm at low speeds (~20mph) and low rpm (~2k). This is starting to
worry me since I'm in New York and stuck in traffic most of the time hence
lots of knocking. Has anyone else experienced this? Any suggestions on how
to get rid of this?

Aj

Have not experienced this and the knock sensor should take care of this. I
would take it back to the dealer and have them check it out.

Acceleration tests have shown that the base RSX is actually tuned for
higher octane than 87 Octane. 87 is probably listed in your owners
manual as a marketing tool to capture those car buyers who don't want to
pay for high octane fuel (LOL).

Why not try 89 octane? A number of base owners claim to get better gas
mileage with 89 as well (search www.clubrsx.com).

Apparently this is correct. I couldn't believe it when I first
encountered the claim a while back.

That's what has been discussed in several newsgroups. Honda seems to
trust their knock sensors overmuch.

Thx,

I've tried 93 octane and the knocking does reduce, although not completely.
I've got about 14K on my base rsx. Hope it's not a design flaw, there are
quite a few other folks experiencing this...

Where did you read that the base is apparently tuned for higher than 87
octane??

Default Re: RSX Base 03 still knocks with 87 octane gas

Sports Compact car ran some acceleration (and I believe dyno) tests
which showed this. Also a search on ClubRSX with add evidence.

My advice to you is to try a higher octane fuel, if it doesn't seem to
affect performance for you, don't bother with it.

Default Re: RSX Base 03 still knocks with 87 octane gas

The base RSX has a 9.8 compression ratio...which is slightly high. So I
would think that 87 fuel would not be sufficient.

Give it 89 or 93.

Default Re: RSX Base 03 still knocks with 87 octane gas

Turns out that the knocking sound had nothing to do with the octane. Acc'd
to the dealer it was related to the auto tensioner giving a little too much
slack too the chain belt under low rpms. Normal behavior acc'd to them...
