Engine Oil Cross Reference: How to Match the Right Alternative

If you're looking for an engine oil cross reference, you need more than just the same SAE grade.

For example, SAE 5W-30 from one manufacturer may not meet the same API or ACEA standards as another.

Key Factors in Engine Oil Matching

1. SAE Viscosity Grade

Examples:

• 0W-20
• 5W-30
• 10W-40

2. API Classification

Such as:

• API SP
• API CK-4
• API SN

3. ACEA Standards

Common in European vehicles:

• ACEA A3/B4
• ACEA C3

4. Manufacturer Approvals

Examples:

• Mercedes-Benz approvals
• BMW Longlife standards
• Volkswagen specifications

A professional oil cross reference tool compares all these parameters — not just viscosity.

Why Engine Oil Substitution Requires Accuracy

Using the wrong equivalent oil can cause:

• Sludge formation
• Turbocharger damage
• Increased emissions
• DPF issues
• Warranty voidance

A verified oil equivalency matching system helps avoid these costly mistakes.
