oil additives BUICK PARK AVENUE 1993 Owners Manual

Ethanol is ethyl or grain alcohol. Properly-blended fuel
that is no more than
10% ethanol is fine for your car.
Methanol is methyl or wood alcohol.
Fuel that is more than 5% methanol is bad for
your vehicle. Don’t use it.
It can corrode metal
parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t be covered under your Warranty. And even at
5%
or less, there must be “cosolvents” and
corrosion preventers in this fuel to help avoid
Gasolines for Cleaner Air
Your use
of gasoline with detergent additives will help
prevent deposits from forming
in your engine and fuel
system. That helps keep your engine in tune and your
emission control system working properly. It’s good for
your vehicle, and you’ll be doing your part for cleaner
air.
Many gasolines are now blended with materials called
oxygenates. General Motors recommends that you use
gasolines with these blending materials, such as MTBE and ethanol.
By doing
so, you can help clean the air,
especially
in those parts of the country that have high
carbon monoxide levels.
In addition, some gasoline suppliers are now producing
reformulated gasolines. These gasolines are specially
designed to reduce vehicle emissions. General Motors
recommends that you use reformulated gasoline. By
doing
so, you can help clean the air, especially in those
parts of the country that have high ozone levels.
You should ask your service station operators if their
gasolines contain detergents and oxygenates, and if they
have been reformulated to reduce vehicle emissions.
Fuels in
Foreign Countries
If you plan on driving in another country outside the
U.S. or Canada, unleaded fuel may be hard to find. Do
not use leaded gasoline. If you use even one tankful,
your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled,
the exhaust
system can corrode, and your engine oil can deteriorate
quickly. Your vehicle’s oxygen sensor will be damaged.
All
of that means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business
in the
country where you’ll be driving.

0 SAE low-30
As shown in this chart, SAE 1OW-30 is best for your
vehicle. However, you can use
SAE 5W-30 if it’s
going to be colder than
60 OF (1 6 ” C) before your
next oil change. When it’s very cold, below
0°F
(- 18 ” C), you should use SAE 5W-30.
These numbers on an oil container show
its viscosity, or
thickness. Do not use other viscosity oils such as SAE
low-40 or SAE 20W-50.
0 Energy Conserving I1
Oils with these words
on the container will help you
save
fuel.
This doughnut-shaped logo (symbol) is used on most oil
containers to help you select the correct oil.
You should look for this on
the oil container, and use
only those oils that display the logo.
GM Goodwrench@ oil (in Canada, GM Engine Oil)
meets all the requirements for your vehicle.
Engine Oil Additives: Don’t add anything to your oil.
Your Buick dealer is ready
to advise if you think
something should be added.
When to Change Engine Oil: See if any one of these
is true for
you:
0 Most trips are less than 4 miles (6 km).
It’s below freezing outside and most trips are less
The engine is at low speed most of the time (as in
door-to-door delivery, or in stop-and-go traffic).
0 You tow a trailer often.
than
10 miles
(16 km).
Most trips are through dusty places.
If any one of these is true for your vehicle, then
you
need to change your oil and filter every 3,000 miles
(5 000 km) or 3 months -- whichever comes first. (See
“Change Oil Soon” in the Index.)
If none of them is true, change the oil every 7,500 miles
(12 500 km) or 12 months -- whichever comes first.
Change
the filter at the first oil change and at every
other oil change after that. (See “Change
Oil Soon” in
the Index.)
Engine Block Heater: An engine block heater can be a
big help
if you have to park outside in very cold
weather,
-20” F (-29 “C) or colder. If your vehicle has
this option, see “Engine Block Heater.”
