- Lift and Secure: Safely raise your vehicle and secure it on jack stands or ramps.
- Locate Drain Plug and Pan: Place your drain pan directly under the oil pan drain plug.
- Drain Oil: Using the correct wrench, carefully loosen and remove the drain plug. Be prepared for hot oil. Let the oil drain completely, which can take 10-15 minutes.
- Replace Drain Plug: Once drained, clean the drain plug and install a new crush washer. Reinstall the drain plug and tighten it to the manufacturer’s specified torque using your torque wrench. Do not overtighten!
- Remove Old Filter: Position the drain pan under the oil filter. Use an oil filter wrench to loosen the old filter. Once loose, carefully spin it off by hand. Expect some oil to spill.
- Prepare New Filter: Apply a thin film of new Mobil 1 0W-40 full synthetic oil to the rubber gasket of the new oil filter. This ensures a good seal.
- Install New Filter: Screw the new filter on by hand until the gasket makes contact with the engine block. Then, tighten it an additional 3/4 to 1 full turn, or as specified by the filter manufacturer. Do not overtighten with a wrench!
- Add New Oil: Lower the vehicle. Locate the oil filler cap on top of the engine. Using a funnel, slowly add the recommended amount of Mobil 1 0W-40 full synthetic oil.
- Check Level: After adding the oil, wait a few minutes for it to settle. Check the oil level on the dipstick. It should be between the “min” and “max” marks. Add more if necessary.
- Start Engine and Check for Leaks: Start the engine and let it run for a minute or two. Check under the vehicle for any leaks around the drain plug or oil filter. The oil pressure light should turn off.
Post-Change Verification and Disposal
After the initial run, shut off the engine and wait 5-10 minutes for the oil to settle again. Recheck the dipstick and top off if needed. It’s common for the level to drop slightly as the new oil fills the filter.
Finally, reset your oil life monitor if your vehicle has one. Proper disposal of used oil is critical. Pour the old oil from your drain pan into an empty, sealable container (like the empty Mobil 1 bottles). Most auto parts stores and municipal recycling centers accept used motor oil for free.

“Too Thin” for My Engine? Understanding Viscosity Myths
A common misconception is that a “0W” oil is “too thin” to protect an engine, especially in older vehicles. However, the “0W” refers to its cold-weather viscosity, meaning it flows like a 0-weight oil when cold.
At operating temperature, it performs like a 40-weight oil, providing robust protection. The synthetic base stocks in Mobil 1 0W-40 are engineered to maintain this viscosity across a wide temperature range better than conventional oils.
If your owner’s manual recommends a 0W-40 or a range that includes it, you can trust it’s the correct viscosity for your engine’s design, even if you’re used to higher “W” numbers from older vehicles.
Oil Consumption: Is It Normal with Synthetics?
Some drivers report slightly higher oil consumption when switching from conventional to synthetic oil. This can sometimes be attributed to synthetics’ superior cleaning properties, which can clean deposits from piston rings, potentially leading to increased, but usually minimal, consumption.
It can also be due to the synthetic oil’s ability to penetrate smaller passages. However, excessive oil consumption is rarely caused by the oil itself. It’s more likely an indication of an underlying engine issue like worn piston rings, valve seals, or leaks.
Monitor your oil level regularly. If consumption is significant (e.g., more than a quart every 1,000-2,000 miles), consult a mechanic to diagnose the root cause.
When to Call a Professional: Red Flags and Warning Signs
While DIY maintenance is empowering, knowing when to seek professional help is crucial for safety and preventing further damage. Call a licensed professional if you encounter any of these issues:
