Not sure how or where to get your Buick LeSabre’s oil changed? Turn to Firestone Complete Auto Care! We are experts in car care — not just tires. We know all about motor oil, too. After all, "Oil is the blood of the engine. It's the #1 thing you can do for your car," says our maintenance technician, Brianna.
Buick recommends having your 1990 Buick LeSabre’s motor oil changed at regular intervals. Check the interval for your vehicle mileage in the table above. Your LeSabre may need an oil change right away if your check engine/oil change light is on, you hear knocking sounds coming from the engine, sense an oil smell in the cabin, or see an excess amount of vehicle exhaust. You might need an oil change more frequently than what’s recommended by Buick if you regularly haul heavy loads, frequent dusty roads, enjoy off-roading, or drive at low speeds for long distances. In general, being extra-diligent about oil changes won’t damage your Buick LeSabre. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.
Whether you need high mileage oil, synthetic oil, or conventional oil, you'll find the right 1990 Buick LeSabre motor oil at Firestone Complete Auto Care. Buick has specifically identified either synthetic or conventional as the ideal engine oil for your 1990 LeSabre. This oil helps lubricate engine parts, keep the engine cool, and prevent harmful substances from accumulating in the engine. In an oil change service, an auto technician will change your LeSabre’s oil, replace and recycle your used oil and filter, inspect the rest of your car’s filters, top-off essential fluids, and visually inspect the rest of the vehicle. You can rest assured knowing that we seek to do what’s best for your LeSabre by considering your driving style, and the number of miles on your odometer.
What motor oils are available at Firestone Complete Auto Care? We carry the best because your LeSabre deserves the best. Check your owner's manual and talk with a technician to select the right Buick LeSabre oil, whether it's Quaker State® Advanced Durability™ conventional oil, Pennzoil® High Mileage Vehicle® motor oil, Pennzoil Platinum® Full Synthetic motor oil with PurePlus™ Technology, or Shell Rotella® heavy-duty engine oil. With so many motor oil brands in the market, why do we carry these brands? They are tested and trusted. For example, when tested on taxi fleets from coast to coast, Quaker State was shown to provide double the protection when compared to the industry standard.  Pennzoil is another option. Unlike traditional synthetic motor oils, the Pennzoil Platinum® Full Synthetic line of motor oils with PurePlus® Technology is formulated from pure natural gas, which helps lead to better performance. Then there's Shell Rotella heavy-duty engine oil. It's expressly designed for gasoline and diesel engines that need to survive the toughest working conditions, and is fortified to deliver increased wear protection, heightened performance in extreme temperatures, and improved oxidation resistance.
