BRZ Oil Change - Everything You Need to Know

Demystifying the BRZ Oil Change: Everything You Need to Know (and Why It Matters!)

Alright, fellow car enthusiasts, let's talk about something super important, especially if you're lucky enough to own a Subaru BRZ, Toyota GR86, or Scion FR-S (we all know they're practically siblings!). We're diving deep into the world of the BRZ oil change. It might sound like a mundane chore, but trust me, for a car designed to be driven and enjoyed, it's nothing short of a ritual.

Why pay so much attention to a simple oil change? Well, unlike your average commuter car, your BRZ has a high-revving, direct-injected boxer engine that absolutely thrives on clean, high-quality lubrication. Skimping here isn't just a bad idea; it can genuinely impact your car's performance, longevity, and even its characteristic exhaust note. Think of it as feeding your performance athlete the best possible fuel – because that's exactly what fresh oil is for your BRZ.

Why Your BRZ's Oil Change Isn't Just "Any" Oil Change

Let's be real, the FA20 or FA24 engine in your BRZ isn't like the old pushrod V8 in grandpa's classic. It's a modern marvel, engineered for a specific blend of performance and efficiency. This means a few things for your oil:

First off, it's a boxer engine. This flat configuration has its own unique way of distributing oil and handling heat. While fantastic for a low center of gravity and handling, it puts specific demands on the oil to keep all those horizontal cylinders happy.

Secondly, the direct injection system, particularly on the FA20, can lead to a phenomenon called fuel dilution. Tiny amounts of fuel can make their way past the piston rings and into the oil, degrading its protective properties over time. This isn't unique to BRZs, but it's a good reminder that your oil is working hard and breaking down. The FA24, while newer, still benefits from the same careful consideration.

Finally, you probably drive your BRZ differently. It's a fun car, meant for spirited drives, canyon carving, and maybe even the occasional track day. All that adds stress to your engine and, you guessed it, your oil. High RPMs, aggressive cornering, and rapid acceleration really put your engine's lifeblood through its paces. So, a proper BRZ oil change isn't just about draining old sludge; it's about giving your engine a fresh start, ready for its next adventure.

When to Give Your BRZ a Fresh Drink (The "When")

This is where things can get a little fuzzy, even among enthusiasts. The manufacturer's recommendation for a BRZ is typically every 6 months or 7,500 miles, whichever comes first. That's a good baseline, but here's the kicker: your driving style might demand more frequent changes.

Spirited Driving/Track Use: If you're hitting the track or regularly enjoying those backroads with a heavy foot, consider changing your oil every 3,000 to 5,000 miles or 3-4 months. The extra stress on the engine means the oil breaks down faster.
Daily Driver (Light Use): If your BRZ is mostly a commuter car with gentle driving, sticking closer to the 6-month/7,500-mile interval might be fine.
Time vs. Miles: Don't forget the time component! Even if you don't drive much, oil degrades just sitting in the engine due to heat cycles and condensation. If you only put 1,000 miles on it in 6 months, change it anyway.

Many BRZ owners (myself included!) lean towards the more frequent side, often opting for a 5,000-mile or 6-month interval even with mixed driving. It's cheap insurance, honestly, and gives you peace of mind that your beloved boxer is always running on its best stuff.

Gathering Your Arsenal: What You'll Need for a BRZ Oil Change

Thinking about doing a DIY BRZ oil change? Awesome! It's a super rewarding experience, and you'll get to know your car a little better. Here's a checklist of what you'll need:

Engine Oil: This is crucial. For the FA20 (2013-2021) and FA24 (2022+), you'll need 0W-20 synthetic oil. Make sure it meets API SN/SP or ILSAC GF-5/GF-6 standards. Many enthusiasts prefer full synthetic for its superior protection and longevity. Your BRZ will typically take around 5.8 to 6.0 quarts with a filter change. I usually buy a 5-quart jug and an extra single quart to top it off.
Oil Filter: A new one is non-negotiable. OEM Subaru filters (often labeled "Tokyo Roki" or "Denso") are generally highly regarded. There are also excellent aftermarket options from brands like Purolator, Wix, or Mann. Just make sure it's the correct fitment for your BRZ.
Crush Washer (Drain Plug Gasket): This tiny copper or aluminum washer ensures a leak-free seal for your drain plug. It's a one-time use item, so always replace it! Many oil filters come with a new one, but always double-check.
Tools:
- Socket Wrench and Socket: You'll need a 17mm socket for the drain plug.
- Oil Filter Wrench/Pliers: There are specific cap-style wrenches for Subaru filters that make removal a breeze, especially given its somewhat awkward location.
- Drain Pan: A pan large enough to hold at least 7 quarts of oil.
- Funnel: Essential for mess-free refilling.
- Torque Wrench: Highly recommended for proper tightening of the drain plug (28-30 ft-lbs) and oil filter (hand-tight plus 1/4-1/2 turn, or specific torque if the filter dictates). Over-tightening either can cause serious headaches.
- Jack Stands or Ramps: Crucial for safely lifting the car and getting underneath it. Never work under a car supported only by a jack!
- Wheel Chocks: For extra safety.
- Gloves and Rags/Shop Towels: Because oil changes can be messy!

The Nitty-Gritty: How to Perform a BRZ Oil Change

Okay, ready to get your hands a little dirty? Here's a quick rundown of the steps. Remember, safety first!

Warm It Up (A Little): Drive your BRZ for 5-10 minutes to get the oil warm (not scorching hot!). Warm oil flows better and will drain more completely.
Lift and Secure: Park on a level surface. Chock the rear wheels. Safely lift the front of the car using a jack and then secure it with jack stands or drive it up onto ramps.
Locate and Prepare: Get under the car. You'll see the oil pan (a large, flat metal pan) and the drain plug (a bolt on the bottom). The oil filter on the FA20 is on the front of the engine, pointing downwards, slightly behind the exhaust headers. On the FA24, it's typically more accessible on top of the engine, near the front.
Drain the Old Stuff: Place your drain pan directly under the drain plug. Using your 17mm socket, carefully loosen and remove the drain plug. Be ready for a gush of hot oil! Let it drain completely, which usually takes 10-15 minutes.
Replace the Drain Plug: Once the oil flow has slowed to a drip, wipe down the drain plug. Install a new crush washer onto the drain plug. Reinstall the drain plug and tighten it with your torque wrench to 28-30 ft-lbs. Don't overtighten it, you can strip the threads!
Remove the Old Filter: Move your drain pan under the oil filter. Use your oil filter wrench to loosen the old filter. Once loose, carefully spin it off by hand. More oil will drain out here, so be prepared.
Prep and Install the New Filter: Take your new oil filter. Dip a clean finger in some fresh engine oil and lubricate the rubber gasket on the new filter. This helps it seal properly. Screw the new filter on by hand until it's snug. Then, use your filter wrench to give it an additional 1/4 to 1/2 turn or to the manufacturer's specified torque (often around 12 ft-lbs). Again, don't overtighten!
Refill with Fresh Oil: Lower your BRZ back to the ground. Pop the hood and remove the oil filler cap. Place your funnel in the oil filler neck. Slowly pour in about 5.5 quarts of the new 0W-20 synthetic oil.
Check the Dipstick: Reinstall the oil filler cap. Start the engine and let it run for about a minute to circulate the new oil and fill the filter. Turn the engine off. Wait 5 minutes for the oil to settle. Pull out the dipstick, wipe it clean, reinsert it fully, then pull it out again. Check the oil level. It should be between the "low" and "full" marks. Add more oil slowly, a little at a time, until it's right at the "full" mark.
Final Checks: Check under the car for any drips or leaks from the drain plug or oil filter. If everything looks good, you're all set! Don't forget to reset your oil maintenance light (refer to your owner's manual for instructions, it's usually a button sequence).

Pro Tips & Common Pitfalls

Don't Rush: Take your time, especially if it's your first time.
Label Your Oil: Keep a small sticky note or marker handy to note the date and mileage of your BRZ oil change.
Proper Disposal: Never pour used oil down the drain! Most auto parts stores or municipal recycling centers will accept used motor oil for free. Be responsible!
Torque Wrench is Your Friend: Seriously, it prevents costly mistakes like stripped threads or cracked oil pans.
Inspect Things: While you're under the car, take a quick peek at other components like suspension, exhaust, and brakes. It's a great opportunity for a general inspection.
Have Fun! There's a certain satisfaction that comes from doing your own car maintenance.
