Amazon offers five quarts of Quaker State Motor Oil starting at $11.87 after Subscribe & Save discounts. Redeem this rebate for a final starting price of $8.87. (The starting price and rebate amount vary based on the type of oil you buy.) That's a buck under our mention from last week and the best price we've seen for any Quaker State oil in this quantity. You can choose from 1-quart and 5-quart options, but the total must be at least five quarts. Rebate expires December 31.

Be sure to cancel Subscribe & Save after your order ships to avoid being billed for subsequent shipments.
