Brake And Clutch Fluid - Opel Antara Owner's Manual

214 Service, maintenance
Not every engine oil available on the
market meets the quality requirements,
always check the required specification
and rating is marked on the container.
If engine oil of the required quality is not
available, a maximum of 1 litre of ACEA
A3/B4 or A3/B3 grade may be used (only
once between each oil change). The
viscosity should be of the correct rating.
Use of ACEA A1/B1 and A5/B5 engine oil is
expressly forbidden, since they can cause
long-term engine damage under certain
operating conditions.
Engine oil additives
The use of engine oil additives could cause
damage and invalidate the warranty.
Engine oil viscosity
SAE 0W-30, 0W-40, 5W-30 or 5W-40
The SAE viscosity rating defines the ability
of an oil to flow. When cold, oil is more
viscous than when hot.
Multigrade oil is indicated by two figures.
The first figure, followed by a W, indicates
low temperature viscosity and the second
figure the high temperature viscosity.
Coolant and antifreeze
Use antifreeze of recommended
specification: silicate-free LLC (Long Life
Coolant).
The system is factory-filled with coolant
designed for frost protection down to
approx. -28 °C. This concentration should
be maintained all year-round.
Coolant additives intended to give
additional corrosion protection or seal
against minor leaks can cause function
problems. Liability for consequences
resulting from the use of coolant additives
will be rejected.

Brake and clutch fluid

Only use DOT4 brake fluid.

Warning
Brake fluid is poisonous!
Over time, brake fluid absorbs moisture
which will reduce braking effectiveness.
The brake fluid should therefore be
replaced at the specified interval.
Brake fluid should be stored in a sealed
container to avoid water absorption.
Ensure it does not become contaminated
with fluids containing mineral oil (oil,
petrol, cleaner) as this can damage the
seals and sleeves of the brake system.

Warning
Due to its corrosive nature, it must not
come in contact with the paintwork. Flush
any escaped brake fluid with plenty of
water.
