Is how to write off gas as a business expense a business expense?

Gas expenses are deductible when they are incurred for business purposes, such as driving to meet clients, attending business meetings, or transporting goods. The IRS allows taxpayers to deduct actual expenses (including gas) or use the standard mileage rate. Personal commuting costs are not deductible. For mixed-use vehicles, only the business-use portion is deductible, and taxpayers must keep detailed records, such as a mileage log, to differentiate between personal and business use. For example, if a vehicle is used 60% for business, only 60% of the gas expenses can be deducted.
