- Evolution Big Twin and XL Sportster kits use mineral oil — synthetic oil is not recommended for these engines
- A variation attribute in the product selector combines “1984–2017 Twin Cam & Evolution” under one label; refer to the kit contents table above to confirm the correct oil type for your specific engine before ordering
- Milwaukee-Eight kit covers 2017 and newer Big Twin models with no defined end date — confirm current model year compatibility at time of purchase
