Most cars now say in their owners manuals to change oil every 7500 miles, and that is regular oil not synthetic. I think for anyone that isn't changing oil often, because of time or whatever reason, they should use a good synthetic like Mobil1 and change it 12 months or 12000 miles max.
Floor Planning. Floor planning is a method of financing inventory purchases, where a lender pays for assets that have been ordered by a distributor or retailer, and is paid back from the proceeds from the sale of these items.
Sales. Sales are purchases of the company's goods or services by customers. For companies using accrual accounting, this includes both cash payments and payments made on account. The sales account, otherwise known as the revenue account, is found at the top of the company's income statement. However, at the end of every account period the sales account is closed to equity as part of the closing process. Therefore, the aggregation of sales over the company's history is found in the equity accounts.
