On average, limousine gas tanks range from around 20 gallons up to 50 gallons or more. Stretch limousines and luxury limousines typically have larger gas tanks to accommodate for longer trips and their higher fuel consumption due to their increased size and weight. Smaller limousines, such as town cars or SUV limousines, may have gas tanks closer to the 20-gallon range.
It's important to keep in mind that the actual fuel capacity and efficiency of a limousine can be influenced by numerous factors, including vehicle model, engine size, manufacturer specifications, usage conditions, and any custom modifications
