Parts for your 2012 Honda Stream-Engine oil

2012 Honda Stream engine-oil — what it does and how to look after it

Based on Honda owner’s and service manuals for RN6–RN9 Stream models with the R18A (1.8L) and R20A (2.0L) i-VTEC petrol engines, engine oil is absolutely required on the 2012 Honda Stream. Those factory sources specify Honda Genuine Motor Oil or an equivalent meeting API SN (or later) and ILSAC GF-5 (or later), with SAE 0W-20 as the preferred viscosity. That makes engine-oil 100% relevant to this vehicle.

In this Stream, oil does much more than simple lubrication. It creates a protective film between moving parts, reduces friction and wear, helps carry heat away from hotspots, suspends contaminants so the filter can trap them, and guards against corrosion. It also supports precise hydraulic functions inside the i-VTEC system. Clean, correctly graded oil means smoother running, better fuel economy, and longer engine life.

For normal use in Australia and New Zealand, 0W-20 full-synthetic is the go-to pick. Where 0W-20 isn’t available, a quality 5W-30 that meets Honda’s API/ILSAC specs can be used. Typical refill volumes sit around 3.7–4.2 litres depending on 1.8L vs 2.0L and whether the filter is changed, the dipstick is the final call. Aim for mid-way between the marks after a short settle time on level ground.

Service timing is straightforward: most local workshops treat the Stream to fresh oil and a filter every 10,000 kilometres or 12 months, whichever comes first. If the car sees lots of short trips, towing, dusty roads, or hot stop–start city work, bringing that down to 5,000–7,500 kilometres is smart. Some Streams are equipped with Honda’s Maintenance Minder, if fitted, follow its A/B prompts and sub-codes.

• Warm the engine, drain oil fully, fit a new crush washer, and replace the filter with a quality unit.
• Torque the sump plug correctly, refill with the right grade, idle and recheck level and leaks.
• Reset the service reminder (if fitted) and recycle used oil responsibly.

Owners should watch for low level, a rapid darkening to gritty texture, or rising consumption between services. Topping up with the correct grade prevents aeration and timing issues, and sticking with the right viscosity keeps cold starts easy and fuel use tidy.

Popular questions about 2012 Honda Stream engine-oil

What oil grade suits a 2012 Honda Stream?
Honda specifies SAE 0W-20 meeting API SN/SP and ILSAC GF-5/6 for the 1.8L and 2.0L i-VTEC petrol engines. That viscosity supports efficient cold starts and proper VTEC operation. If 0W-20 isn’t on the shelf, a quality 5W-30 that meets the same specs can be used until the next change.

How much oil does it take?
Expect roughly 3.7–4.2 litres with a filter change, depending on whether it’s the 1.8 or 2.0. Always fill short, run the engine, let it settle, then top up to the dipstick’s upper mark rather than relying on a flat number.

How often should the oil be changed?
For most Australian and New Zealand conditions, every 10,000 km or 12 months is a safe rule. With frequent short trips, towing, or dusty routes, shorten the interval. If the car has Honda’s Maintenance Minder, follow its service codes.
