Engine Oil; Check Oil Level - Buick PARKAVENUE 1996 Manual

Your Park Avenue Ultra has
a 3800
Supercharged
engine. Buick chose supercharging rather than
turbocharging because Buick emphasizes smooth,
refined power.
The supercharger is a device which is 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 Buick engine.
The power steering pump and reservoir are mounted
on the rear (driver's side) of the engine block. See
"Maintenance Schedule" in the Index for when you
should check the fluid.
