2022 Vauxhall Astra Engine Oil and Fluids Information
The engine at the core of your 2022 Vauxhall Astra is a feat of engineering designed to deliver performance, efficiency, and dependability. It is essential to pay close attention to the fluids that circulate within this dynamo if it is to operate efficiently. The engine oil, transmission fluid, coolant, and other fluids are the lifeblood of your vehicle, ensuring optimal performance and preventing deterioration. This guide will cover the fundamentals of engine oil and lubricants for your 2022 Vauxhall Astra, including their functions, recommended types, and recommended maintenance procedures. Join us as we explore the world of fluids that maintain your Astra in pristine condition.
Engine Oil
Check the engine oil level manually on a regular basis to prevent damage to the engine. Ensure that the correct specification of engine oil is used.
Recommended fluids and lubricants 3
The maximum engine oil consumption is 0.6 l per 600 miles.
Check with the vehicle on a level surface. The engine must be at operating temperature and switched off for at least five minutes.
Caution
It is the owner’s responsibility to maintain the proper level of an appropriate quality oil in the engine.
Different dipsticks are used depending on engine variant. 
Pull out the dipstick, wipe it clean, reinsert it fully, pull out and read the engine oil level.
When the engine oil level has dropped to the MIN mark, top up the engine oil.
We recommend the use of the same grade of engine oil that was used at last change.
The engine oil level must not exceed the MAX mark on the dipstick.
Caution
Overfilled engine oil must be drained or suctioned out. If the oil exceeds the maximum level, do not start the vehicle and contact a workshop.
Fit the cap on straight and tighten it.
Engine Coolant
The factory filled coolant provides freeze protection down to approx. -37 °C.
Caution
Only use approved antifreeze.
Coolant and antifreeze
Coolant level
Caution
Too low a coolant level can cause engine damage. 
If the cooling system is cold, the coolant level should be above the MIN mark. Top up if the level is low.
Warning
Allow the engine to cool before opening the cap. Carefully open the cap, relieving the pressure slowly.
To top up, use a 1:1 mixture of released coolant concentrate mixed with clean tap water. If no coolant concentrate is available, use clean tap water. Install the cap tightly. Have the coolant concentration checked and have the cause of the coolant loss remedied by a workshop.
Washer Fluid
Fill with clean water mixed with a suitable quantity of approved windscreen washer fluid which contains antifreeze.
Caution
Only washer fluid with a sufficient antifreeze concentration provides protection at low temperatures or a sudden drop in temperature.
Brakes
Depending on the driving style, the brake wear may vary significantly. The brake wear may increase when the vehicle is driven over short distances, e.g. in the city.
It may be necessary to have the condition of the brakes checked, even between vehicle services.
Unless there is a leak in the circuit, a drop in the brake fluid level indicates that the brake pads are worn.
Once new brake linings are installed, do not brake unnecessarily hard for the first few journeys.
Brake Fluid
Warning
Brake fluid is poisonous and corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be between the DANGER and MAX marks.
If fluid level is below DANGER seek the assistance of a workshop.

FAQs
Engine oil lubricates engine components, reduces friction, and aids in heat dissipation to ensure seamless operation.
It is recommended that you check your engine oil level every month or before lengthy trips using the dipstick.
Consult your owner’s manual for the recommended viscosity and specification of engine oil. Modern engines typically utilize synthetic lubricant.
Change the engine oil and oil filter in accordance with your vehicle’s maintenance schedule, typically every 7,500 to 10,000 miles or as indicated in your owner’s manual.
Yes, you can convert to synthetic oil, but you must follow the correct procedures and consult your owner’s manual for instructions.
As recommended in your owner’s manual, check your transmission fluid every 30,000 to 60,000 miles.
Use the transmission fluid specified in your vehicle’s owner’s manual to maintain appropriate shifting and performance.
Coolant replacement intervals differ, but it’s generally recommended every 30,000 to 60,000 miles or as advised in your manual.
Power steering fluid enables simple and smooth steering. Check it frequently and replenish it as necessary.
Brake fluid replacement intervals differ, but are typically recommended every 20,000 to 45,000 miles or as specified in your owner’s manual.
Windshield washer fluid assists in maintaining a clear windshield for optimal visibility. When the reservoir is depleted, refill it.
Check the engine coolant level in the reservoir on a regular basis and top it off if necessary, particularly before long trips.
Differential fluid lubricates the gears in the differential, assuring reliable and smooth power distribution to the wheels.
Distilled water can be used as a temporary coolant in an emergency, but it must be replaced as quickly as possible with the proper coolant.
Original equipment manufacturer (OEM) fluids are recommended for optimal performance and durability, but high-quality aftermarket fluids that meet the manufacturer’s specifications are acceptable.
