Engine Oil

Recommended Oil

Oil is a major contributor to your
engine's performance and longevity.
Always use a premium-grade deter-
gent oil. You can determine an oil's
SAE viscosity and Service Classifica-
tion from the API Service label on the
oil container. It should look like this:
Maintenance

The numbers in the middle tell you
the oil's SAE viscosity or weight.
Select the oil for your car according
to this chart:
Ambient Temperature
An oil with a viscosity of 5W-30 is
preferred for improved fuel economy
and year-round protection in your
Acura. You may use a 10W-30 oil if
the climate in your area is limited to
the temperature range shown on the
chart.
A fuel-efficient oil is recommended
for your Acura. This is shown on the
API Service label by the words
"Energy Conserving I I . " This oil is
formulated to help your engine use
less fuel.
The API Service label also tells you
the service classification of the oil.
Always use an oil that says "API
Service SG." This service rating may
also include other designations, such
as CD. These additional classifica-
tions are not a problem, as long as
the label also carries the SG classifi-
cation. An oil that is only classified
SF is not recommended.

Additives

Your Acura does not need any oil ad-
ditives. Purchasing additives for the
engine or transmission will not
increase your car's performance or
longevity. It only increases the cost of
operating your car.
