Castrol oils – choosing engine and transmission oil

Castrol offers oils for different engine types and gearboxes. In this milionczesci.pl category, you can compare Castrol products, including the EDGE and TRANSMAX ranges. The selection may also include other Castrol operating fluids, so always check the intended use on each product page.

How to choose Castrol engine oil

Follow the vehicle manufacturer's requirements: permitted SAE viscosity, the appropriate ACEA or API quality classification, and the specific OEM standard or approval. Labels such as 0W-30, 5W-30 and 5W-40 indicate viscosity grades but do not by themselves confirm engine compatibility. Two Castrol 5W-30 products may have different applications.

Castrol EDGE and TRANSMAX transmission oils

The EDGE range includes engine oils with different specifications and applications. TRANSMAX products are designed for specific transmission types; distinguish between manual, automatic and other gearbox designs. A 75W-90 or 80W viscosity grade does not replace checking the required transmission specification.

What to check before buying

  • Model year, engine version and service recommendations.
  • Viscosity and standards listed on the label and technical data sheet.
  • Pack size and required oil quantity.
  • Product part number and any vehicle manufacturer approval.
