Follow the dates
The manufacturing date on the product’s certificate of approval is when the product was made and put into a storage tank. The use-by date is calculated based on shelf life and reflects when the product is put into its primary packaging, which can be weeks or months after it was made.
We began laser etching shelf-life information onto our turbo oil quart cans in July 2019. Prior to that, such information was embossed. The shelf-life period begins when the product is packaged. If your dates are embossed, confirm the product is still usable.
