The 2018 Honda Civic 1.5 Turbo takes about 3.7 quarts (3.5 liters) of engine oil when you perform a full oil change with a new filter; without replacing the filter, the amount is typically around 3.0 quarts (2.8 liters).
Official capacity and oil type
Honda specifies the oil capacity for the 1.5L turbo engine as 3.7 quarts (3.5 liters) with the filter. The amount you add can vary slightly if you don’t replace the filter during the change. The recommended oil type for this engine is 0W-20 full synthetic.
To guide your planning, consider the following commonly cited figures:
- 3.7 quarts (3.5 L) with a new oil filter installed
- About 3.0 quarts (2.8 L) if the filter is not replaced (drain only)
These figures are intended to help you plan a complete oil change. Always verify the final oil level with the dipstick after filling and running the engine to operating temperature.
Oil type and maintenance recommendations
Using the right oil and following standard maintenance helps the turbocharged 1.5L run smoothly and efficiently:
- Viscosity: 0W-20 synthetic motor oil
- Typical change interval: about every 7,500 miles (12,000 km) or as indicated by Honda’s maintenance minder
- Oil filter: replace with every oil change
note: driving conditions, climate, and local manufacturer guidance can adjust recommended intervals. Always consult the owner's manual or a Honda service center for your exact schedule.
How to check and top up oil safely
Following proper steps helps ensure you don’t overfill or miss the correct oil level during a refill:
- Park on a level surface and turn off the engine. Wait several minutes for oil to settle.
- Open the hood and locate the engine oil dipstick. Pull it out, wipe clean, reinsert, and then pull out to check the level.
- Using a funnel, add small amounts of 0W-20 oil at a time, checking the dipstick after each addition.
- Continue until the dipstick shows the oil level between the MIN and MAX marks.
- Replace the dipstick, secure the oil cap, start the engine, and run for a minute. Recheck for leaks and recheck the dipstick once more after a few minutes with the engine off on a level surface.
After topping up, ensure the engine is cool and the level remains within the recommended range. Do not overfill, as excess oil can cause pressure and engine issues.
Summary
For a typical 2018 Honda Civic 1.5 Turbo with a full oil change and new filter, plan to use about 3.7 quarts (3.5 liters) of 0W-20 synthetic oil. If the filter isn’t replaced, you may need around 3.0 quarts (2.8 liters). Always verify the level with the dipstick after filling, and follow Honda’s manual for precise maintenance intervals and specifications.
