Vehicle Care 10-19

Viscosity Grade

SAE 5W‐30 is the best viscosity

grade for the vehicle. Do not use

other viscosity grade oils such as

SAE 10W‐30, 10W‐40, or 20W‐50.

If in an area of extreme cold, where

the temperature falls below −20°F

(−29°C), an SAE 0W‐30 oil should

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, always select an oil that

meets the dexos1 specification or

equivalent. See “Specification” for

more information.

Engine Oil Additives/Engine

Oil Flushes

Do not add anything to the oil.

The recommended oils with the

dexos specification and displaying

the dexos certification mark are all

that is needed for good performance

and engine protection.

Engine oil system flushes are not

recommended and could cause

engine damage not covered by the

vehicle warranty.

What to Do with Used Oil

Used engine oil contains certain

elements that can be unhealthy for

your skin and could even cause

cancer. Do not let used oil stay on

your skin for very long. Clean your

skin and nails with soap and water,

or a good hand cleaner. Wash or

properly dispose of clothing or rags

containing used engine oil. See the

manufacturer's warnings about the

use and disposal of oil products.

Used oil can be a threat to the

environment. If you change your

own oil, be sure to drain all the oil

from the filter before disposal. Never

dispose of oil by putting it in the

trash or pouring it on the ground,

into sewers, or into streams or

bodies of water. Recycle it by taking

it to a place that collects used oil.

Engine Oil Life System

When to Change Engine Oil

This vehicle has a computer that

indicates when to change the

engine oil and filter. This is based

on a combination of factors which

include engine revolutions, engine

temperature, and miles driven.

Based on driving conditions, the

mileage at which an oil change is

indicated can vary considerably.

For the oil life system to work

properly, the system must be reset

every time the oil is changed.

Z06, ZR1, and Grand Sport models

have a racetrack‐ready dry sump

engine lubrication system. This

high‐performance system operates

differently than a standard engine

lubrication system and requires a

special procedure when changing

the engine oil and filter. See Engine

Oil on page 10‑14.
