I buy fuel in bulk, store it in one tank, and fill my company vehicles from the bulk tank. How do I determine the gasoline expense per vehicle on the TurboTax vehicle expense worksheet. I use actual expenses per vehicle instead of mileage.

You would need to track the number of gallons you are putting in each vehicle when you put it in the vehicles then multiply it by the amount you paid for the gas to fill up the big tank. There is no other way to determine how much gas you are using in which vehicle. Basically, it should be done like you are going to the gas station with a "receipt" for each vehicle whenever they are filled up.

Is this the only way? I would have to buy a gallons counter for the tank. Do i have to enter per vehicle? Or can i just enter a total fuel cost for the year in a different section?

It depends. You may be able to figure it out by estimating the miles per gallon per vehicle and then prorate for each vehicle based on that.  I would guess you have a general idea about miles per gallon on all vehicles you operate.  If you decided to list the fuel in total as an expense for your business you need to be able to verify that all fuel is used 100% for business purposes or if not, be sure to reduce that figure for any personal use percentage.
