What oil should I put in my BRZ?
The BRZ typically calls for a full-synthetic engine oil that meets the car’s specification, most commonly a 0W-20 grade that complies with ILSAC GF-6 and API SN or better. Always verify the exact specification for your model year in the owner's manual or with a dealer.
Understanding BRZ oil requirements
Across BRZ generations, from the 2.0-liter FA20 in earlier models to the 2.4-liter FA24 in newer editions, the engine is designed for high-rev, lightweight performance. The manufacturer’s guidance favors a lightweight, fully synthetic oil that maintains viscosity across a wide temperature band and resists breakdown under spirited driving. Using an oil that doesn’t meet the spec can affect lubrication, fuel economy, and warranty coverage.
Viscosity options and when to use them
Below are common viscosity options you’re likely to encounter for BRZ models, with guidance on when each is appropriate.
- 0W-20 synthetic oil — the standard choice for most BRZ models; supports fuel efficiency and quick cold-start protection; should meet ILSAC GF-6 and API SN (or newer).
- 5W-30 synthetic oil — acceptable in some markets or if the manual allows it; may be preferred in very hot climates or for high-mileage engines, provided it meets GF-6/API SN.
- Avoid non-synthetic oils or significantly heavier grades unless specifically approved by the manual; using the wrong viscosity can reduce protection and performance.
Bottom line: For the vast majority of BRZs, 0W-20 synthetic is the recommended baseline; 5W-30 can be an option only if your manual approves it and your climate/conditions justify it.
Choosing a brand and ensuring compatibility
Brand matters less than meeting the correct viscosity and specifications. Pick a synthetic oil that clearly states GF-6 (or newer) and API SN or better, and favors products that are labeled as fully synthetic. If you prefer OEM alignment, Subaru/Toyota Genuine oils are available through dealers and some retailers, but many reputable aftermarket brands also meet the required specs.
Before listing the specific options, consider this guidance: the key factors are viscosity, synthetic status, and certification. Always verify the product’s specifications on the bottle or the manufacturer’s site, and ensure it matches your owner’s manual.
- 0W-20 synthetic engine oils that meet GF-6 (and API SN or newer) and are labeled as fully synthetic.
- Popular and widely available choices include Mobil 1, Castrol Edge, Pennzoil Ultra Platinum, Valvoline SynPower, and Subaru/Toyota Genuine oils, all offered in 0W-20.
- When in doubt, select a reputable brand and confirm the exact specification printed on the bottle or listed by the manufacturer.
Bottom line: Always verify the exact spec on the bottle and in the owner’s manual, and opt for a fully synthetic oil that meets GF-6/ILSAC standards.
Maintenance and driving considerations
Oil choice is part of a broader maintenance picture. Your driving style—daily commuting, spirited driving, or track days—affects oil life and performance. The BRZ’s manual outlines recommended change intervals and notes conditions that constitute severe service.
Below is practical guidance on how driving conditions influence oil maintenance.
- Normal driving: follow the manufacturer’s recommended interval, typically around 6,000–7,500 miles or every 6–12 months, whichever comes first, assuming moderate climate and no tracking.
- Severe or track use: shorter intervals, commonly 3,000–5,000 miles; monitor oil temperature and level and consider oils with higher thermal stability for repeated high-load sessions.
- Always keep the oil level within the proper range and avoid overfilling; inspect oil condition and level after track days or high-load driving.
In short, pairing the right synthetic oil with timely changes and attentive maintenance will help preserve BRZ performance and reliability.
Summary
For most BRZ models, the recommended starting point is a full-synthetic 0W-20 oil that meets GF-6 and API SN specifications. Always check your exact model year and climate in the owner's manual, as some climates or high-mileage scenarios may permit 5W-30 if explicitly approved. Choose a reputable brand, verify the oil’s specs on the bottle, and adhere to the recommended change intervals to protect the engine and maintain warranty coverage.
Is it okay to put 5W-30 instead of 0W-20?
It is not recommended to use 5W-30 instead of the recommended 0W-20, as the thicker oil can cause premature engine wear by not reaching all parts and potentially void your warranty. While some engines can handle the switch, especially in hot climates or for older vehicles, using the wrong viscosity can negatively impact fuel efficiency and lead to issues with modern engine components like variable valve timing. Always check your owner's manual for the correct oil specification, and in an emergency, use the correct oil at your next oil change.
Risks of using 5W-30 instead of 0W-20
- Engine wear: The main risk is that the thicker 5W-30 oil may not flow through the very tight tolerances in a modern engine as well as 0W-20, potentially leading to premature wear or failure.
- Component issues: Modern engines are designed for precise oil flow, and using a thicker oil can interfere with components like the variable valve timing system.
- Warranty issues: Using an oil that is not specified by the manufacturer can void your engine's warranty if an issue arises.
- Reduced fuel economy: 0W-20 oil is specified to improve fuel efficiency, and using a thicker oil will reduce that benefit.
When it might be acceptable
- Emergency situations: In an emergency where you can't find 0W-20, using 5W-30 is a short-term solution, but you should switch to the correct oil at your next oil change.
- Hot climates or hard use: Some experts suggest that in very hot climates or for heavy-duty use like towing, a thicker oil like 5W-30 might provide better protection, as the same engine models sometimes recommend 5W-30 in different regions of the world.
Best practice
- Consult your owner's manual: Always use the oil viscosity specified in your car's owner's manual for the best performance and protection.
- Change to the correct oil: If you've used the wrong oil, change it to the correct 0W-20 at the next opportunity.
Can BRZ use 5w30?
Recommended especially for turbo-charged engines, Genuine Subaru Certified 5W-30 Synthetic Motor Oil provides superior protection against oil breakdown for cleaner running and long engine life.
What oil to use for Subaru BRZ?
SAE 0W-20
Subaru BRZ Oil Grade
In all climates, Subaru recommends using SAE 0W-20 as the preferred formulation. If you can't find it in your area, you can also go with SAE 5W-20. Both will help your BRZ achieve the adrenaline-surging performance that you deserve on the Winter Haven roads.
