How to Use 15W

1. Open the driver's side door of your E320 and locate the hood lever in the footwell. It will be on the left, underneath the front dashboard. Pull the lever to loosen the hood.
2. Open the hood to reveal the engine bay, and then locate the oil filler cap located on top of the engine, on the right-hand side.
3. Remove the dipstick located near the engine oil filler cap and wipe it clean with a paper towel. Insert the dipstick back into the engine and pull it out again to read the current engine oil level.
4. Loosen the oil filler cap and set it aside. Insert a plastic funnel into the oil filler neck and slowly pour in additional oil as necessitated by the engine oil level reading.
5. Remove the funnel and screw the oil filler cap back on, and then close your hood.
