Actually Ford sold Foci with a "lifetime" air filter (not really "lifetime",
but it didn't have a routine replacement interval). It is not impossible to
do. In fact most people probably change air filter too often. Here is a link
to the Visteon website where they discuss their long life filtration system
(300,000 miles - i.e., lifetime for most cars):
Ideally vehicles should have a filter restriction indicator to prevent
chaning filters needlessly. My farm tractors all have these indicators, and
it is surprising how dirty a filter gets before it triggers the light.
That reminds me of a Boston joke;
A guy gets in the express line at a Boston supermarket with an
overflowing cart. The cashier looks him over and asks him if he is a
student to which he answers "Yes". "So tell me", she asks, "are you
from Harvard and can't count or are you from MIT and can't read?"
Every 30K miles? No wonder I missed it. It's not a frequent item.
But I did find it in the maintenance chart, right on the top, under the
column titles. I must have skipped that row, too.
By the way, searching for the downloadable service manuals for the
'94 Accord, I see such designations on the various web sites as Accord
1994 CD7 CD9 USDM JDM and CE1 CE2. What do they mean by those
abbreviations? I found one for just plain 1994 Accord but that turned
out to be for the Coupe. How do I find one for the LX model?
The manuals found on the Web tend to be for European models. There are
significant differences betwen US models and those meant for other parts of
the world, so it's not a good idea to rely on non-US manuals for
information. Honda's UK division posted some those manuals for free on
their Website for a while, which is why they're everywhere now.
As for the "CD", CE", etc., those are internal Honda designations for the
various Accord chassis. They are different from the EX, LX, etc., that
you'll find on the trunk lid.
"CA" was the gereration made from 1986 to 1989, "CB" was made from 1990 to
1993, "CD" from 1994 to 1997, etc. The numbers after the letter code refer
to the bodystyle (sedan, wagon...) and to the engine that was installed.
"EX", LX", etc., are the trim line designations that Honda used to denote
the models' retail price class.
The only really reliable source for US-specific Honda information is

Just my experience: I found the UK site manuals to be fine for repair
procedures for years for my Civics. The maintenance schedules are a
little different for the UK compared to the U.S.
Not sure how much Do-It-Yourself inclined the OP is, but for others, a
94 Accord manual may be had at
Factory service manuals and their excerpts are online free one way or
another more and more these days. www.honda-tech.com is a good
resource for finding factory service manuals and excerpts.
www.autozone.com has what appear to be Chilton manuals free online.
The Chilton procedures are often identical to the factory service
manuals. The 94 Accord's maintenance schedule is published for free
there. The air cleaner is supposed to be replaced every 30k miles of
two years, whichever comes first. People will scoff at some of this,
but I think the truth is it depends on what one's budget is. I have
never purchased a factory service manual and instead have used the
resources above. I do brakes, timing belts, suspension work, valve
adjustment everything but alignments, and always having a procedure on
OP: The LX coupe, LX sedan, DX coupe and DX sedan all use the same
engine. Hence the engine maintenance for these two sub-models will be
Oh, I don't know ... Just checking one major maintenance item in the '94
Coupe maint. schedule, the timing belt replacement, shows a big
difference compared to my Owner's Manual: the Coupe manual specifies
every 60 K miles, my OM says 90 K. Big difference!
Engines, belts, and pulleys are mechanically identical the world-over. A
Unitta timing belt installed in a SOHC F-series engine doesn't care if the
engine resides in England or in North Carolina.
Some years ago, Honda suffered a couple of class-action lawsuits, for two
1) originally /not/ mentioning timing-belt replacement in their Owner
Manuals, and then
2) specifying a too-conservative replacement interval of 60K when they
finally /did/ mention it.
These had the result of forcing Honda to stretch US maintenance intervals
as far as they dared. Honda never changed the maintenance intervals for
non-US models. America's idiotic tort system is therefore ultimately
responsible for the differences you see.
I meant that the UK manuals will have the same timing belt replacement
interval for both the Accord Coupe LX and the Accord Coupe DX (along
with sedan versions): All are 60k for these cars when driven in the UK
(= United Kingdom). I think it is more frequent in the UK because of
the weather etc. there. Canada likewise has more severe weather, so if
memory serves, going to the Canadian Honda site will turn up a 60k
interval, too. The Autozone site shows the figures to use in the U.S.
for both the DX and LX, either coupe or sedan in "normal" conditions:
90k or six years, whichever comes first, and the same as your owners'
manual. Both the Autozone site and your Owners' manual have a 60k mile
interval for "severe" conditions.
Owner's manuals for U.S. Hondas have made this distinction for decades
now. From googling, it seems Toyotas also make this distinction.
I have owned three different generations of Civics over 20 years now.
Been working on them for ten+ years.
What make of car did you drive before?
I see at the online U.S. 1994 Accord Coupe owners' manual linked below
that I am wrong and for timing belts, there is no distinction made in
the actual owners' manual. Same for 1991 Civics.
I do not know why Autozone's site, which pertains to U.S. cars, shows
two different maintenance schedules for the 94 Accord and other
Hondas, one for normal and one for severe, with a 60k interval for the
Accord under severe conditions. The American Honda site (under
"Owner's Link") does not list any change interval for the timing belt
for older Civics and Accords, though going to the owners' manual at
rjanisis above shows, again, no distinction for timing belts.
I checked too, and I'm also wrong, at least about the OP's 4-cylinder
Accord and other 4-cylinder Hondas.
It turns out that it's the newer V6 models that have a dual schedule: If
the vehicle is driven "regularly" at temperatures over 110F, or below -20F,
then the 60K interval is followed instead of the 90K interval.
