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.
A permanent account, also called a real account, is a balance sheet account that is used to record activities that relate to future periods. The reason they are called permanent accounts is because they are never closed at the end of an accounting period. In a sense, they are permanent fixtures on the financial statements. Permanent accounts carry the ending balances of the balance sheet to the beginning of the next year. For instance, the ending inventory balance for year one is the beginning inventory balance for year two.
