Good evening, @tammyleninsky.

I'm here to provide you with some clarification with tracking expenses for each of your service vehicles.

For each vehicle you have, you can set up 4 accounts and name the accounts the vehicle name. Once you've set up those accounts, you can create subaccounts for those expenses like fuel, oil change, and parts for the vehicles. 

To set up the parent accounts here's how:

1. Click on Lists at the top, then choose Chart of Accounts.
2. Select the Account drop-down menu, then pick New to create a new account.
3. Go to an account type, then Continue.
4. Enter the account details.
5. Select Save and Close.

To create subaccounts for the expenses:

1. Click Lists in the top menu, go to Chart of Accounts.
2. Choose the Account drop-down, then select New to create a new account.
3. Pick the account type, Continue.
4. Type in the account details, then choose the Subaccount of checkbox.
5. Select Save and Close.

Once you've completed the steps above, you'll be able to track expenses for each service vehicle you have.

Let me know if the steps above do the trick. Thank you for reaching out to the Community. Have a safe and productive rest of your week!
