5-20 oil on 98 Accord-I4?
Dear Experts,
I bring my 98 4-cyl Accord to Honda dealer for regular oil change.
Lately, they started use 5-20 oil for oil changes for all the cars.
The advisor told me that unless I explicitly tell them otherwise, they
will be using 5-20 oil as default.
My question is: Since my car is not new(7 years, 105K miles),
can I still use 5-20 engine oil? Will it offer less protection than
5-30 or 10-40? After all, 5-20 oil is newer and more expensive.
Some people tell me to switch to 10-40 oil as car ages. When should
I be switching to that grade?
Thanks for your help in advance.

Re: 5-20 oil on 98 Accord-I4?
I would just go with what the dealer recommends. that's usually the best
thing. i'm wondering about that weight of oil myself because i have a real
old civic that calls for 5w-30 and i wonder if it would be better with
5w-20.

I would go with whatever the manual specifies, irregardless of what the
dealer says. I assume it is not under warranty, so if anything goes wrong,
the owner foots the bill.

there is no such word as "irregardless". Use either "irrespective" or

I would use whatever grade your original manual calls for, which is
probably either 5W-30 or 10W-30. I am not aware of Honda recommending
the application of 5W-20 to vehicles which did not originally specify it.

10W-40 was common in older cars, which tended to become oil-burners with
age. It doesn't flow as freely as 5W-30 so it doesn't lubricate quite as
well. All things being equal, all viscosities would be fine. It is the film
strength, not the viscosity, that provides the wear protection. But low
viscosity helps the oil actually get to where the lubrication is needed, so
in the real world of modern engines it lubricates better. I agree with the
others, though; if Honda felt 5W-20 was the right choice they would have
specified it.
Changing to 10W-40 in a Honda is an end-of-life move; an acknowledgement
that something has already gone wrong (like an inadequate air filter being
used for too long, or too infrequent oil changes) and the engine is being
nursed along another year or two. Improvements in engine production have
ended the oil consumption problem in most engines.

Here is what I learned about the chemistry of motor oil about 8 years
ago (I needed the information for a technical paper). The information
may be out of date, but I would think it still applies.
So called multiviscosity oil (a misnomer) contains hydrocarbon
polymers. Polymers are molecules built around long chains of carbon
atoms, maybe 100 or so atoms in the chain. Plastics are polymers. DNA
is a polymer. Polymer just means a long chain of similar units.
These long molecules are tightly coiled up at low temperature (due to
hydrogen bonds) but at higher temperatures, the molecules uncoil and
get tangled together. This "tangling" effectively gives the oil a
higher viscosity and is what causes the viscosity of the oil to remain
higher as the temperature is increasaed.
The problem is, as I understand it, that for oils with a wide
difference between low and high temperature viscosity (such as 10W-40)
such a large quantity of polymer must be added that the polymers
begins to gunk things up. So it is best to stay with an oil where the
two numbers are closer together.
My Honda owners manual recommends 5W-30, but allows 10W-30 in certain
temperature ranges. Down here in Texas (where the temperature right
now is 81 degrees) it never gets cold enough to neede the lower
viscosity oil, so I always insist on 10W-30. The polymer problem MAY
be why Honda and other manufacturers have gone to 5W-20 as a
recommendation.
On the other hand, there are many characteristics of motor oil that
are a lot more important than actual viscosity. As another poster has
said, these include such things as film strength, ability to hold
contaminants in suspension, etc. Modern motor oils are far superior
to the stuff I had to pour in my car 50 years ago and are an important
part of the reason why automobile engines can easily go 200,000 miles
or more with no problems.
Just my $0.02 worth.

Tell the advisor that you do not want to pay for the more expensive 5W-20
oil when the cheaper 5W-30 is just fine for your vehicle.

Re: Please do not reiterate
Hmmm...
I actually answered Elmo's post where he stated that there was no such word
etc ....
So I used the same "error", by using a similar "not correct word".

Re: 5-20 oil on 98 Accord-I4?
for the right price i would use the more advanced motor oil 5w-20. more than
likely it is a better oil for your car. your owners manual was written
before that oil was even thought of probably and now it's out and if your
manual could be rewritten it may actually be calling for w20. i wouldn't
worry about it. if the car is running good and you talk to the dealer and
they tell you its a better oil. than you can use it.

Well said! As oils evolve Honda has changed reccomendations that may differ
from your owners manual. The industry specifications continue to change and
as oils improve they become better for your vehicle even though they may be
a different weight.

The two weights are usually the same or very similar in price.
There is no one who knows your vehicle better than your dealer. There is no
advantage to your dealer to reccomend one over the other, but he has an
incentive to give you the right service to maintain you as a customer. There
is an official Honda chart that you can ask to see, that will show you what
Honda reccomends for your vehicle. I think you will find that your dealer is
providing the correct weight of oil for your Accord.
