Accrued oil is not commonly referred to as "Dash." If you're looking for information on "Dash" in relation to oil, it might be confused with the cryptocurrency called Dash, which is unrelated to oil or petroleum.
However, in the context of oil, "accrued oil" typically refers to oil that has been produced but not yet sold or delivered, which may be measured in inventory. If you meant to refer to a specific type of oil or a certain context where "Dash" is used, please provide more details, and I'll be glad to help clarify!
