Here's why:
* Engine variations: The 1.4 engine in a 2004 Astra could have different specifications depending on the exact model and its engine code.
* Oil type changes: Oil recommendations have evolved over time, and what was suitable in 2004 might not be the best choice now.
* Driving conditions: Oil viscosity and type should be considered based on your climate and driving habits (city vs. highway).
To find the right oil, I recommend:
1. Consult your owner's manual: This is the most reliable source for your specific car model.
2. Check the oil cap: The oil cap might have a sticker with recommended oil specifications.
3. Contact a Vauxhall dealership or qualified mechanic: They can provide the most accurate information based on your car's VIN.
Important considerations:
* API rating: Look for an API (American Petroleum Institute) rating that meets or exceeds the recommendation for your car.
* Viscosity: The oil viscosity (SAE number) should be appropriate for your climate.
* Oil type: Consider whether you need conventional, synthetic, or semi-synthetic oil.
Remember, using the wrong oil can harm your engine. Always refer to your owner's manual or consult a professional for the correct engine oil for your Vauxhall Astra 1.4 54 reg.
