Acura RL and Premium Gas
The Acura RL is designed to operate on 91 octane premium unleaded gasoline. While it may run fine with lower octane fuels, it is not running optimally as designed, and you may lose optimum miles per gallon (mpg) using lower octane rated fuels.
High compression engines require premium fuel to prevent the tendency to knock during certain driving conditions. Acura’s use high compression engines for maximum power output, and high compression and forced induction engines require high octane to prevent pre-ignition, which can cause mechanical engine damage.
It’s important to note that while the Acura RL is designed for premium fuel, it is not an absolute requirement. The car will automatically adjust, and knock sensors detect knocking in a matter of milliseconds and adjust the timing. However, to get the most out of your vehicle, it is highly recommended to use premium gas.
In summary, while the Acura RL does not necessarily “require” premium gas, it is designed to operate on 91 octane premium unleaded gasoline for optimal performance and fuel efficiency.

Can my Acura take regular gas?
Do All Acuras Require Premium Gas? Like we stated, premium gas is only recommended on the MDX, RDX, TLX, RLX, and ILX Acura models. You’ll be safe on our Cherry Hill roads using regular gas in these automobiles. However, the engines in these models are designed for optimal performance when high-octane fuel is used.
Can Acura take 89 gas?
Do all Acuras require premium gas? The answer is no; however, the recommendation to use higher-octane fuel is rooted in several performance-related considerations.
And you might notice a degrade in performance. I still take a regular won’t permanently damage your engine. But. It’s always better to top it off with premium.
The V6 is designed to run on regular and it should run just fine on regular. But that does not mean it is tuned and designed for only 87. It simply means the car has the knock resistance and monitoring, and tune tables required for the car to run good and safely on 87.
What happens if you mix 87 and 91 gas?
The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive. “That said, if your vehicle requires premium fuel, it’s a good idea to top it off with the good stuff as soon as you’re able,” the website said.
What happens if I 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.
According to the manufacturer, premium gas is required only for the Acura NSX. However, it is recommended for the MDX, RDX, TLX, and ILX for optimal performance. The answer to the question,” Do all Acuras require premium gas?” is no — but there are many reasons why a higher-octane fuel can benefit your Acura vehicle.
There’s nothing wrong with mixing premium and regular gas in the same tank. In fact, this is how midgrade gas is formulated at the station. Rather than drawing from a separate storage tank for each octane rating, gas pumps actively mix high-octane fuel with lower-octane fuel to create midgrade gas.
