Getting a brz oil change done right is one of those simple tasks that keeps your boxer engine happy for a long time. If you've spent any time behind the wheel of a Subaru BRZ or its twin, the Toyota 86/GR86, you know these cars are all about the experience. They're built for corners, high revs, and pure driving joy. But to keep that 2.0L or 2.4L flat-four humming along without a hitch, you've got to stay on top of the basics.
Honestly, the BRZ is one of the most DIY-friendly cars out there when it comes to routine maintenance. Subaru actually did us a massive favor by putting the oil filter right on top of the engine bay. It's sitting there in a little "cup" specifically designed to catch drips. Compared to cars where you have to reach past a burning hot exhaust manifold just to find the filter, the BRZ is a absolute dream.
Why the boxer engine is a bit picky
The FA20 (in the first gen) and the FA24 (in the second gen) engines are unique. Because the cylinders lay flat, oil flow is incredibly important. You aren't just lubricating parts; you're managing heat and ensuring those tight tolerances stay within spec.
Regularly scheduled maintenance is the difference between a car that hits 200,000 miles and one that ends up on a flatbed. Most owners like to stick to a tighter schedule than what the manual says, especially if they're driving the car hard on backroads or taking it to the track. If you're just commuting, the standard intervals are fine, but for the enthusiasts, a frequent brz oil change is cheap insurance.
What you're going to need before you start
Before you crawl under the car, you want to have everything laid out. There's nothing worse than draining your oil and realizing you're missing the 14mm socket or, heaven forbid, the new oil itself.
Here's the basic shopping list: * 0W-20 Synthetic Oil: Most people swear by Motul, Pennzoil Ultra Platinum, or the OEM Subaru stuff. Make sure you have at least 5 to 6 quarts on hand. * Oil Filter: Stick with the black Tokyo Roki filters (the OEM ones) if you can find them. They're generally considered the best for these engines. * Crush Washer: Do not skip this. It's a tiny metal ring that costs about a dollar, but it prevents leaks at the drain plug. * 14mm Wrench or Socket: For the drain plug. * Drain Pan: Something that can hold at least 6 quarts. * Funnel: Unless you have hands like a surgeon, you're going to spill oil on your intake manifold without one.
Getting the job done
First things first, you'll want the engine to be slightly warm, but not "just finished a track session" hot. Warm oil flows much faster and carries more contaminants out with it. If the car has been sitting, let it idle for five minutes.
Once you've got the front of the car up on ramps or jack stands (always use stands, please!), locate the drain plug. It's pretty easy to spot through the cutout in the under-tray. Position your pan, loosen the 14mm bolt, and let it rip.
Pro tip: While the oil is draining, go back up top and unscrew the oil filter. Because the filter is inverted on the BRZ, the oil will drain back down into the pan rather than spilling all over your engine. It's a genius design, really.
Once the dripping slows down to a crawl, wipe off the drain plug surface, put your new crush washer on the bolt, and thread it back in by hand. You don't need to "gorilla torque" this thing. Just get it snug—about 30 ft-lbs if you're using a torque wrench.
The "Ring of Fire" and the filter
Even though the filter is on top, you might still run into the "ring of fire" if you're working on a first-gen BRZ with aftermarket headers, but usually, that's more of an issue for WRX owners. For us, the filter is just sitting there in its little tray.
Take your new filter and smear a little bit of clean oil on the rubber gasket. This helps it seal properly and, more importantly, makes it easier to get off next time. Screw it on until it's hand-tight. You don't need a wrench to tighten it; your hand strength is plenty.
Filling it back up
Now for the satisfying part. Grab your funnel and start pouring. If you're driving a first-gen BRZ (2013-2020), you're looking at about 5.7 quarts. If you've got the newer 2.4L engine, it takes a bit more—roughly 5.3 to 5.5 quarts depending on how much drained out.
I usually start with 5 quarts, let it settle for a minute, and then check the dipstick. The BRZ dipstick can be a little notorious for being hard to read. It's best to pull it out, wipe it completely dry, stick it back in, and then pull it out again. Look at both sides of the stick; the lower reading is usually the accurate one.
Common mistakes to avoid
Even though a brz oil change is straightforward, people still find ways to mess it up. The biggest one? The double gasket. Sometimes the old rubber O-ring from the previous filter gets stuck to the engine. If you screw the new filter on top of the old gasket, it'll spray oil everywhere the second you start the car. Always check that the mounting surface is clean and bare.
Another classic is the crush washer. People either forget to put a new one on, or they accidentally leave the old one stuck to the oil pan. This leads to a slow, annoying drip that stains your driveway and makes you question your mechanical skills. Just buy a pack of ten washers and keep them in your glove box or toolbox.
Lastly, make sure you're using the right viscosity. 0W-20 is the standard for a reason. These engines have very narrow oil passages, and using a thick "racing" oil on a street car can actually do more harm than good in some cases, especially during cold starts.
How often should you actually do it?
Subaru might tell you that you can go 6,000 or 7,500 miles between changes. If you're an enthusiast, you're probably cringing at that. Most BRZ owners prefer to do a brz oil change every 3,000 to 5,000 miles.
If you track your car, all bets are off. High oil temperatures break down the viscosity much faster. A lot of track rats will change their oil after every two or three events just to be safe. It's a small price to pay when you consider the cost of a replacement FA24 short block.
Wrapping things up
Taking care of your own brz oil change is more than just a way to save fifty bucks at the dealership. It's a way to get to know your car. You get to look under the chassis, check for leaks, see how your tires are wearing, and generally ensure everything is tight and right.
Plus, there's a certain level of peace of mind that comes with knowing exactly what oil went into your engine and that the drain plug was actually torqued correctly. The BRZ is a special car that rewards owners who pay attention to the details. Keep the oil fresh, keep the revs up, and that boxer engine will keep singing for years to come. It's probably the easiest bit of "car guy" work you can do, so grab a wrench and get to it. Your Subaru will thank you the next time you hit your favorite winding road.
