Step-by-Step Oil Change Process

Warm the engine: Run for 2-3 minutes to loosen oil.
Drain old oil: Place a pan under the drain plug (14mm socket).
Replace filter: Remove old filter (oil filter wrench), lubricate new gasket.
Add new oil: Pour 5.5 quarts, check dipstick, top off to "Full" mark.
Dispose responsibly: Take used oil to a recycling center.

Signs You Need an Oil Change

Dark, gritty oil on the dipstick.
Engine noise or knocking sounds.
Oil change light or maintenance reminder.
Exhaust smoke or burning oil smell.
Poor fuel efficiency or sluggish acceleration.

Common Mistakes to Avoid

Over/under-filling: Can damage engine or reduce lubrication.
Wrong oil type: Check the manual for viscosity and specs.
Skipping the filter: Always replace the filter with oil changes.
Tightening too much: Strip the drain plug or filter housing.
Ignoring leaks: Address oil pan or gasket leaks immediately.
