Engine Oil - Pontiac 2000 Bonneville Owner's Manual

Supercharged Engine (If Equipped)
Your vehicle may have a 3800 V6 (L67) Supercharged
engine. The supercharger is a device designed to pump
more air into the engine than it would normally use.
This air, mixed with fuel, creates increased engine
power. Since the supercharger is a pump and is driven
from an engine accessory drive belt, increased pressure
is available at all driving conditions.
The Powertrain Control Module (PCM) works with a
vacuum control to regulate the increased pressure required
during specific driving conditions. When this increased
pressure or boost is not desired, such as during idling and
light throttle cruising, the excess air that the supercharger is
pumping is routed through a bypass. All of these controls,
working together, provide high performance character and
fuel efficiency in the 3800 V6 Supercharged engine.

Engine Oil

If the OIL LEVEL LOW
message appears on the DIC,
or the CHECK OIL LEVEL
light appears on the
instrument panel, it means
you need to check your
engine oil level right away.
For more information, see "Check Oil Level Light" or
"DIC Warnings and Messages" in the Index.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It's a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil dipstick
might not show the actual level.
The engine oil dipstick is
located behind the engine
fans and in front of the
engine oil fill cap. The top
of the dipstick is a round
yellow loop.
