Browse Oil Data

Browse and select from over 19,000 oils contained in the Regional Databases and Custom Datasets. Build a separate shopping cart for Databases or Datasets (shopping carts cannot be combined).

Regional Databases

Data may be purchased here for a particular region for any year beginning with 2005. For the current year, oils collected and tested to date will appear when browsing the database by region. Data from oil collections prior to 2005 is available upon request. Data is organized into the following regional databases:

Custom Datasets

Browse and Create Custom Datasets

Using the data selection tool, filter the database using the criteria shown below to quickly find oils:

  • Brand Name
  • Supplier
  • SAE Grade
  • Service Class
  • Country
  • Region

When selections are made, purchase all or only specific test results for each oil. If all tests are purchased, an Engine Oil Data Report is also included. Data Analysis Tools and a preview of the demographic and oil bottle data is available with any purchase.

Tests Available for Purchase

Results on each test shown below are available for all oils in the database. Regional databases include all test results. Custom datasets may be purchased with all or select results. (Note: not all tests are available in historical data)
