If the manual says 87 octane (or higher), that is all you need to run, 87 octane gas. The engine is designed to run at that octane rating optimally. You can run higher octane gasoline, but all you are doing is spending money you don't need to spend. My daughters Acura TL requires 93 octane fuel and running less impacts performance and can ping. My Ecoboost ...

Every modern (fuel injected) car will run fine on any type of gasoline you can get on a decent gas station. The car has an engine computer that adjusts many parameters multiple times per second to get optimal performance no matter the temperature, air pressure, octane rating, throttle position, hill slope etc. A different octane rating may make a very small ...

87 will work, 89 is optimal, 93 will also work but uses a bit more (will start to run leaner but the computer easily compensates but using more fuel) 87 better for winter (no difference over 89), 89 better for summer (helps when underhood is HOT when you have the A/C running AND trying to keep the engine around operating temp. I would maybe avoid the ...

The acid test is if you try a lower octane fuel, if you hear any "knocking" sounds under hard acceleration (perhaps up a hill), then you definitely need a higher octane rating. As Paulster2 mentions, there will not be any performance improvement, in spite of what a lot of people say. The octane rating is just a measure of resistance to knocking. I have a ...

I recommend using 89 . I have 2015 RAV4 . 89 does give you a better acceleration, you are right. So go with 89 . This is the golden average . Your manual says 87 or higher . So anything above 87 is okay. However, i wouldn't go with 93 . Be cautious 93 may result in unburnt fuel that is not very good

Realistically, if the manual and the manufacturer are stating you should use 87 octane, that's really what you should use. If you purchase more expensive 89, 91, or 93, you are just wasting money. The higher the octane rating, the harder it is for fuel to burn (or ignite). If the vehicle was specified to use 93, then that's what you should buy or you risk ...
