Can you put 89 gas in a Toyota?
The short answer is no, you should not put 89 octane gasoline in a Toyota vehicle. Toyota recommends using a minimum of 87 octane regular unleaded gasoline for most of its models, and using a lower octane fuel can potentially cause engine damage over time.
Understanding Octane Ratings and Toyota Fuel Requirements
Octane rating is a measure of a fuel's resistance to premature ignition, also known as "knocking" or "pinging." Higher octane fuels, like 91 or 93, are less prone to knocking and are typically recommended for high-performance or turbocharged engines that operate under higher compression.
Toyota specifies the minimum octane rating required for its vehicles in the owner's manual. For most Toyota models, the recommended fuel is 87 octane regular unleaded gasoline. Using a lower 89 octane fuel, which is considered "mid-grade," can potentially cause engine knocking and damage over time.
Potential Consequences of Using 89 Octane in a Toyota
- Engine Knocking: Lower octane fuel is more prone to premature ignition, which can cause an audible knocking or pinging sound in the engine. This knocking can eventually lead to engine damage if left unchecked.
- Reduced Performance: Using a lower octane fuel than recommended may result in a noticeable decrease in engine power and acceleration.
- Decreased Fuel Efficiency: The engine may not operate as efficiently with a lower octane fuel, leading to reduced fuel economy.
- Voided Warranty: Using a fuel that does not meet the manufacturer's specifications could potentially void the vehicle's warranty if engine damage occurs.
To ensure the best performance, fuel efficiency, and long-term engine health, it's important to always use the minimum octane fuel recommended by Toyota for your specific model. Consult your owner's manual or contact your local Toyota dealer for the correct fuel requirements.
Is 87 gas better than 89 for Toyota?

Will my car mess up if I put 87 instead of 93?
If you mean putting 87 octane rating in your performance car that wants 93 or higher, it won't harm anything long-term, but performance will suffer as long as the low-grade stuff is in the tank.
Does 89 gas burn faster than 93?
Octane ratings are plastered all over every gas pump, and, contrary to marketing terminology, "premium" does not necessarily indicate a fuel is "better" for your car as much as whether it is "right" for your car. Fuel with an 87 octane rating burns more quickly while higher-octane fuels burn more slowly.
Can you put 89 gas in a premium car?
If your vehicle requires an octane level of 93, using a lower-grade fuel can potentially cause knocking that can damage your engine. If the octane level is a recommendation and not a requirement, you have a bit more latitude to experiment and see how your particular vehicle fares.
Is it OK to mix 89 and 93 gas?
You can absolutely mix octanes, and they mix linearly. So, if you could fill half your tank with 89 and the other half with 93, you'll end up with a tank of exactly 91-octane.
Can I put 89 gas in a Toyota Corolla?
You must only use unleaded gasoline. Select octane rating of 87 (Research Octane Number 91) or higher. Use of unleaded gasoline with an octane rating lower than 87 may result in engine knocking.

With regular kill your ride. Well the short answer is no so in a pinch you can use regular. But you will likely hear an engine knock. And you might notice a degrade in performance.
Is it bad if I put 89 instead of 87?
If your car is telling you 87 is alright, it's designed to run just fine on regular unleaded and using 89 won't improve performance or efficiency. However, if you already have 89 in there, topping off with 87 won't cause any issues. These fuels mix just fine within the tank and will burn effectively in your engine.
Can I put 89 gas in my Toyota Camry?
