The Subaru BRZ uses premium unleaded petrol with an octane rating of 98 RON . However, if unleaded gasoline with an octane rating of 98 RON is not available, unleaded gasoline with an octane rating of 95 RON may be used with no detriment to engine durability or driveability. It is important to note that using a lower octane rating may cause engine knocking, while using a higher octane rating may not provide any additional benefits.

What happens if I put 89 instead of 87?
No Vehicles Need 89-Octane Fuel
At worst, it could cause the engine computer to slow the ignition timing a bit or adjust the fuel injection, potentially lowering fuel economy or performance.
Can you mix 87 and 91 gas?
Is it bad to mix premium and regular gas? Well, not necessarily. If your car requires premium to run smoothly, but you aren’t able to find a station with premium gasoline, it won’t hurt to top off with regular gasoline. You do want to avoid running on regular gasoline for extended periods of time.
Can I put 89 in a BRZ?
These engines are high compression engines. If you run 87 or 89 octane, the fuel will detonate (explode) earlier in the combustion cycle than it should… before it is ignited by the spark plug. This causes knock, and knock can physically damage your pistons as well as your cylinder walls.
What is the best gas for the BRZ?
Typical E10 has an octane rating between 94.5 and 95.5, basically on average 95. E10 is so cheap compared to 95 Octane, that the use of a little more fuel is well offset by the cheaper price. Unfortunately the BRZ/GR86 have very aggressive engine timing and need 98 Octane fuel.
What gas does 2013 BRZ take?
premium gas
The 2013 Subaru BRZ requires premium gas. According to the EPA, fuel-economy ratings are: BRZ with manual transmission: 22/30/25 mpg (city/hwy/combined)
What happens if I accidentally put 87 instead of 91?
If you put lower-octane fuel into your high-octane vehicle, whether by mistake or to save money on gas, you’ll probably notice the effects right away: things like poor fuel economy, reduced acceleration, and spark knock, which sounds like a high-pitched pinging or rattling noise.
Does it matter if I put 87 instead of 91?
Even if your car’s owner’s manual says it requires premium fuel, you’ll probably be OK if you run a little bit of regular. Some cars require premium high-octane gasoline, others just recommend it, and most cars are fine running regular 87-octane fuel (it might even be lower at high altitudes).
Can you use 87 in BRZ?
If you’ve read the owner’s manual by now, you’d know your BRZ requires a minimum of 91 octane to run safely without damage, and that Subaru recommends 93. Anything below 91 will most likely result in lots of detonation, and even motor death.
Can you put 87 octane in a BRZ?
For the best performance and a longer estimated engine life, the Subaru BRZ should be filled with a 91 octane fuel rating and a level of 93 octane fuel is actually recommended for the best in performance and efficiency.
If you drive a Crosstrek, Forester, Outback, Legacy or Ascent, your vehicle is designed to run on 87 octane, or regular fuel. Performance Subaru models – the WRX, WRX STI and BRZ – have a premium fuel requirement, but even with those vehicles, check your manual for information on which fuels are appropriate.
