Want to change your Buick LeSabre engine oil by yourself?

It's no secret that you need regular oil changes to keep your Buick LeSabre engine running smoothly. The recommended change interval is once every 5,000 to 6,000 miles or every 7 to 8 months, whichever comes first.

Usually, people take their cars to a service to perform this operation, but you can change the oil on your Buick LeSabre yourself - it only takes half an hour, but it will save you money.

To change the oil in the engine of your Buick LeSabre, you will need the following things: engine oil (see the table above for the necessary viscosity and volume), an oil filter, a set of wrenchesair filter, a container for the old oil, and some rag.

The oil change order is as follows:

  • Let the engine warm-up: Let the engine run for a few minutes to warm up the oil. This will help the oil flow out of the engine more easily. Don't let the engine run too long - if the oil overheats, you could burn yourself while changing it. 3 to 5 minutes of idling is enough.
  • Locate the oil drain plug: This is typically located on the bottom of the engine. Place the drain pan underneath the plug.
  • Remove the drain plug: Loosen and remove the drain plug using a wrench or socket set. Be careful, as the oil will begin to flow out immediately.
  • Allow the oil to drain: Allow the oil to drain completely into the drain pan. This may take a few minutes. Unscrew the oil filler cap to allow the oil to drain faster.
  • Remove the oil filter: Using a filter wrench, loosen and remove the oil filter. Allow any remaining oil to drain into the drain pan.
  • Replace the oil filter: Install the new oil filter, and lubricate the rubber gasket with fresh oil before tightening it.
  • Install the drain plug: Once the oil has finished draining, reinstall the drain plug and tighten it securely.
  • Add new oil: Using a funnel, add oil to the engine through the oil filler cap. Check the chart above for the correct amount and type of oil to use.
  • Check the oil level: After adding new oil, check the oil level using the dipstick. Add more oil if necessary.

We recommend changing your Buick LeSabre air filter whenever you change your oil. Over time, it becomes clogged with dirt, dust, and other debris, negatively affecting engine performance. The process of changing it is straightforward.

  • Find where the air filter is installed in your Buick LeSabre, open the cover, remove the old filter, and install the new one. Close the air filter cover.
  • Start the engine: Let it run for a few minutes, checking for any leaks.
  • Dispose of the old oil: Pour it into a sealable container and take it to a recycling center or automotive service facility that accepts used oil.
