A 1922 Chevy Impala doesn’t exist, so I’m assuming you mean a later Chevrolet Impala. To change the oil, warm the engine a little, drain the old oil from the drain plug, replace the oil filter, reinstall the plug, then refill with the correct oil type and amount from the owner’s manual.

Key takeaways

• Chevrolet didn’t make an Impala in 1922.
• Use the exact oil grade and capacity for your Impala’s year and engine.
• Always support the car safely on level ground before going underneath.
• Check for leaks and recheck the oil level after running the engine.

Deeper dive

I’m assuming you meant a different Impala year, since the Impala name started much later. The basic process is: park level, let the engine get slightly warm, turn it off, lift the front safely if needed, remove the drain plug and let the oil drain fully, swap the filter, lightly oil the new filter gasket, reinstall the plug with a new washer if needed, refill, start the engine for 30 seconds, then shut it off and check the dipstick. If you send the exact year and engine size, I can give the oil capacity, filter type, and step-by-step details.
