Spark Plug Question

Hi: I want to put platinum tip spark plugs in my '92 Accord, but I was
told by Canadian Tire that I need to tell them whether my engine is an
"A1" or an "A6" (its a 2.2 L, by the way). Any ideas on how I can
find this out? Thanks in advance. - Paul

 

Probably stamped on your engine. On my 91 Civic, it's stamped a little
below the distributor, on the engine front. Have a flashlight handy and
some rags and Windex to wipe gunk off. Big letters, like one inch or so,
I'd say. I think they're lined up vertically on the engine.

might also help. Seems like if it's an EX, it's an A6. If not an EX, it's
an A1.

 

Wow - many thanks. That did the trick! - Paul

 

Save your money, just get Densos or NGKs.

 

How about if I like to use high octane fuel? I generally fill with 91
octane since I personally believe this has contributed to the
longevity of my engine ( > 200,000 miles). I've heard that the catch
here is extra wear on the plugs with hotter temps, so as my old plugs
are about shot and I intend to keep to keep this car for as long as
possible, I was considering platinum plugs. Thanks. - Paul

 

Uh-huh.
How?

Premium gasoline has two desirable characteristics - higher octane and
higher detergency (as a rule). The higher octane is important to engine life
only if the engine is designed to use it. Low octane fuel in a high
compression engine can cause detonation (ping) and damage valves, pistons
and rings. But if the engine is designed for 87 octane - check your owner's
manual - or if it has a knock sensor, premium is a waste of money. Even
regular grades of many brands of gasoline like Chevron or Shell/Texaco has
plenty of detergency. High octane gas doesn't burn any hotter except at high
throttle in cars that have high compression *and* knock sensors.

Hi Mike. I'm not sure about my '04 Accord LX,
but I'm pretty certain my '92 Accord is supposed to
have 87 regular. Maybe it was just a subjective
impression on my part to believe that the 91 octane
extended the engine life, but in any event your comments
are food for thought. Many thanks. - Paul

 

Hi Steve: Thanks for your input on the status of your own '91
Accord. You really didn't need to get sarcastic. I was just
stating an impression and asking an honest question. - Paul
