Honda StepWGN 1.5 i-VTEC L15B (2023): Oil Filter Replacement

The 2023 StepWGN is the sixth generation (RP) with the 1.5 L15B turbocharged gasoline engine. The oil is changed every 15,000 km or 12 months according to the maintenance schedule. The oil filter is normally changed every 30,000 km or 24 months, and every 15,000 km or 12 months under severe conditions. In practice, it is convenient to change the filter at every oil change. The filter is a spin-on type, located on the outside of the engine. The underbody splash shield fasteners need to be partially removed.

Key figures

  • Oil capacity with filter change
    about 3.5 L (3.7 qt), the amount to add in step 9; without a filter change, about 3.2 L (3.4 qt)
  • Oil viscosity
    0W-20 synthetic, add it in step 9
  • Drain plug socket size
    17 mm, a 17 mm socket with ratchet for step 4
  • Oil change interval
    15,000 km or 12 months, under severe conditions 7,500 km or 6 months, which tells you when to plan the job
  • Filter change interval
    30,000 km or 24 months, under severe conditions 15,000 km or 12 months, per the schedule, but it is convenient to change it at every oil change

Check these values against the manufacturer’s specification for your vehicle before you start.

Tools

10
  • 17 mm socket with ratchet (drain plug)
  • oil filter wrench (strap or cup type)
  • torque wrench
  • screwdrivers (Phillips and flat-head)
  • drain pan of 5 L (5.3 qt) or larger
  • funnel
  • shop rags
  • lift
  • pit
  • or reliable jack stands

Step by step

12 steps
  1. Warm up the engine for 2-3 minutes so the oil becomes fluid, then shut it off. Park the car on level ground and raise it on a lift or secure it on jack stands. Place jack stands only at the factory support points.
  2. Remove part of the lower engine undercover. It is usually held by several quarter-turn quick-release screws and two Phillips screws. Slide the cover back and lower it. You do not need to remove it completely.
  3. Open the oil filler cap on top of the engine so the oil drains faster.
  4. Place the drain pan under the oil pan drain plug and remove the plug with a 17 mm socket. Drain the oil completely, which takes a few minutes.
  5. While the oil is draining, move the pan under the oil filter. Unscrew the filter counterclockwise with the filter wrench. The filter may be on tight. Residual oil will spill out of it, so keep it with the opening facing up.
  6. Wipe the filter mounting surface on the engine with a rag. Make sure the old sealing ring has not stayed behind on the engine.
  7. Lubricate the rubber gasket of the new filter with a thin layer of fresh oil. Spin the filter on by hand until the gasket touches, then tighten it about 3/4 of a turn more. If a tightening torque is printed on the filter housing, use that. Do not overtighten the filter with the wrench.
  8. Wipe the drain plug and its seat in the oil pan. Install a new sealing washer and thread in the plug. Check the drain plug torque against the manufacturer's specification. Tighten it with a torque wrench, not "all the way" with a ratchet.
  9. Pour in fresh 0W-20 oil through the funnel. With a filter change you need about 3.5 L (3.7 qt); without a filter change, about 3.2 L (3.4 qt). First add about 3 L (3.2 qt), then top up a little at a time.
  10. Close the filler cap and run the engine for 30-60 seconds. The oil pressure light should go out immediately. Check the drain plug and the filter from under the car for leaks.
  11. Shut off the engine, wait 3-5 minutes, and check the oil level with the dipstick on level ground. It should be between the marks. Add a little oil if needed.
  12. Reinstall the lower undercover. First slide it into the slots and secure the two Phillips screws, then the quick-release screws. Take the used oil and filter to a recycling center.

Common mistakes and warnings

  • Replace the drain plug sealing washer at every oil change
  • Do not overtighten the filter or the plug: you may strip the threads or crush the gasket
  • Hot oil causes burns, so wear gloves and do not open the plug right after a long drive
  • Check the oil level after a test drive
  • The torque values in this guide are approximate; verify the exact figures against the manufacturer's specification
