What is a Mobil Oil Cross Reference Chart?
A Mobil Oil Cross Reference Chart is a detailed guide that maps Mobil-branded motor oils to their equivalent products offered by other oil brands or manufacturers. These charts typically include specifications such as viscosity grades, API service classifications, and industry standards (e.g., ILSAC), making it easier for users to find compatible oils that meet or exceed the requirements specified by vehicle manufacturers.
Key Components of a Cross Reference Chart:
- Brand and product names: Listing Mobil oils alongside competitors’ products.
- Viscosity grades: Such as 5W-30, 10W-40, etc.
- API service classifications: Such as SN, SM, SP, etc.
- Industry standards: Including ILSAC GF-6, API SN, API CK-4, etc.
- Additional specifications: Such as API SN/CF, ACEA, and manufacturer-specific approvals.
Having this information at hand helps ensure that the alternative oil selected offers comparable quality, performance, and protection.

Importance of Cross Referencing Mobil Oil
Using a cross reference chart is crucial for several reasons:
1. Ensuring Compatibility and Performance
Different brands may formulate oils with varying additive packages. Cross-referencing helps verify that an alternative oil meets the necessary specifications for your vehicle's engine, avoiding issues like increased wear, poor lubrication, or engine damage.
2. Cost Savings and Availability
Sometimes, Mobil oils may be unavailable locally or may be more expensive than alternatives. Cross-referencing enables consumers to find equivalent oils that are more affordable or readily available while maintaining engine safety.
3. Compliance with Manufacturer Recommendations
Vehicle manufacturers specify particular oil standards for optimal operation. Cross-reference charts help identify oils from different brands that meet or surpass these standards, ensuring warranties and performance are maintained.
4. Facilitating Oil Changes and Top-Ups
In emergency or convenience situations, knowing interchangeable oils can help you perform quick top-ups without risking compatibility issues.
