Vehicle Care 385

Selecting the Right Engine

Oil – 2.0L L4 Turbo (LSY)

and 3.0L V6 Twin Turbo

(LGY) Engines

Selecting the right engine oil

depends on both the proper

oil specification and viscosity

grade. See Recommended

Fluids and Lubricants 0 476.

Specification

Use full synthetic engine oils

that meet the dexos1

specification. Engine oils that

have been approved by GM as

meeting the dexos1

specification are marked with

the dexos1 approved logo.

Caution

Failure to use the

recommended engine oil or

equivalent can result in

engine damage not covered

by the vehicle warranty.

Viscosity Grade

For the 2.0L L4 Turbo (LSY)

engine, use SAE 0W-20

viscosity grade engine oil.

For the 3.0L V6 Twin Turbo

(LGY) engine, use SAE 5W-30

viscosity grade engine oil. Cold

Temperature Operation: In an

area of extreme cold, where

the temperature falls below

−29 °C (−20 °F), an SAE 0W-30

oil may be used. An oil of this

viscosity grade will provide

easier cold starting for the

engine at extremely low

temperatures.

When selecting an oil of the

appropriate viscosity grade, it

is recommended to select an

oil of the correct specification.

See “Specification” earlier in

this section.

Selecting the Right Engine

Oil — 6.2L V8 (LT4) Engine

depends on both the proper

grade. See Recommended

that meet the dexosR

specification. Engine oils that

have been approved by GM as

meeting the dexosR

specification are marked with

the dexosR approved logo.
