2021-2023 Opel Astra Engine Oil and Fluids Guide
A versatile and refined compact car, the 2021-2023 Opel Astra provides an exceptional driving experience. Maintaining optimal performance and functionality of your Astra necessitates careful monitoring of the engine oil and fluids it demands. These essential fluids are fundamental in preserving the functionality, durability, and overall dependability of the vehicle.
This introductory section will examine the precise specifications for engine oil and consumables that are necessary for the 2021-2023 Opel Astra. Comprehending these requirements is critical for maintaining your automobile in optimal condition and guaranteeing that it consistently provides a smooth and pleasurable voyage. Let’s delve into the essential information regarding the Opel Astra’s engine oil and lubricants.
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. 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 5 min.
CAUTION
It is the owner’s responsibility to maintain the proper level of an appropriate quality oil in the engine.
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 engine oil.
The engine oil level must not exceed the MAX mark on the dipstick.
We recommend the use of the same grade of engine oil that was used at last change.
Caution
Wipe off any spilled engine oil immediately.
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 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 MIN and MAX marks.
If fluid level is below MIN seek the assistance of a workshop.
Vehicle Battery
The vehicle battery is maintenance-free provided that the driving profile allows sufficient charging of the battery. Short-distance-driving and frequent engine starts can discharge the battery. Avoid the use of unnecessary electrical consumers. Batteries do not belong in household waste. They must be disposed of at an appropriate recycling collection point. Laying up the vehicle for more than four weeks can lead to battery discharge. Disconnect the clamp from the negative terminal of the vehicle battery. Ensure the ignition is switched off before connecting or disconnecting the vehicle battery.
FAQs
In the case of the majority of Opel Astra models, it is advisable to utilise completely synthetic motor oil of viscosity 5W-30.
Changing the engine oil and oil filter every 10,000 to 15,000 miles is the standard recommendation (or as specified in the owner’s manual).
Although synthetic oil is preferable, conventional oil may be utilised as a last resort. It is not, nevertheless, the most optimal option in terms of engine longevity.
Although the exact capacity may differ slightly from engine to engine, it generally retains an estimated 4 to 4.5 pints (or litres) of oil.
Park on a level surface and wait a few minutes after turning off the engine before checking the oil level with the dipstick. For specific guidelines, consult the owner’s manual.
Although maintaining a consistent brand and type of oil is preferable, occasionally combining brands that satisfy the same specifications does not typically pose a problem.
Inoculate the system with a 50/50 blend of distilled water and a high-quality ethylene glycol-based coolant.
Two to five years should pass between coolant changes, contingent upon the specific type of coolant employed. Consult the owner’s manual for particular suggestions.
As municipal water may contain minerals and impurities that can eventually damage your cooling system, distilled water is preferable.
For the power steering system, the majority of Opel Astra models utilise DEXRON III or an equivalent Automatic Transmission Fluid (ATF).
Regularly checking the level of power steering fluid, particularly during routine maintenance, and adding more if required, is recommended.
For precise information regarding the recommended variety and grade of automatic gearbox fluid (ATF) for your vehicle, please refer to the owner’s manual.
Utilising the ATF specifically prescribed by Opel will guarantee the transmission’s optimal performance and longevity.
While there is some variation in the recommended interval, it is generally advised to change the gearbox fluid every 30,000 to 60,000 miles. Consult the owner’s manual for further information.
While it is possible to carry out fundamental maintenance duties such as oil changes, fluid level checks, and fluid topping, it is critical to adhere to the instructions provided in the owner’s manual and utilise the appropriate fluids and procedures. Complex duties might necessitate the assistance of a professional.
