Default Does a 2006 Acura TSX have to have 93 octane?

I have gotten info saying 91+ octane & above. Also, if you use a lesser octane performance will decrease. I want the TSX but with gas I don't want to put 93 octane. If it won't damage the engine or void the warranty I would love to have it. Any definate answers?

Hard to say and make you a Promise. Most Computers will adjust for the Octane. AND, I know it will not hurt the engine, or, I have never seen it happen. What may happen though is you may get the Proverbial Ping/knock noise going up hills and in a fast acceleration. My Truck like the high octane, but, I use the cheaper. It has a Knock sensor to compensate for the Ping/Knock. True any car will perform better with High Octane. Just ask someone who races cars if they use a 89 Octane and why. Look at the Owners Manual to be sure, it, may not ask for the 91+ That about all I know to tell you. Good Luck.

THE BEST WAY TO TELL IS LOOKING IN THE OWNERS MANULE IT WILL GIVE YOU OPERATING REQUIREMENTS THAT NEED TO BE MET BUT I BELIEVE YOU CAN RUN LOWER OCTANE FULE WITH NO NOTICEABLE DIFFERENCE IN PERFORMANCE YOU MIGHT EXPERIANCE A LITTLE SPARK KNOCK OR WHAT THEY CALL DETONATION UNDER HARD ACCELERATION AND IF YOU DO GO TO THE NEXT GRADE OF GASOLINE

If the manufacturer calls for 91+ octane, you must use the higher octane rating to minimize engine knock.The reason for the higher octane numbers is to reduce what is known as spontaneous ignition. For a car to run optimally, a flame front needs to be in the proper direction. Typically the flame front is in a radial direction away from the spark plug.However, with high compression engines (to get more power), gasoline in the cylinder can reach temperatures that will cause spontaneous ignition in various places inside the cylinder. These other flame fronts will collide with the flame front coming from the spark plug, and usually results in what is commonly known as Engine knock. This is the sound you hear then the flame fronts colliding with each other.The shock waves generated WILL cause engine damage and excessive wear over time.If you can afford a new 2006 Acura TSX, then the gasoline cost should NOT be a factor. Considering that 91 octane is typically only $.20-$.30 more per gallon, in a car like this, it will only amount to $3-$4 to fill up your tank as opposed to the lower octane gasoline. If it's the car you want, this additional $3 cost should not be stopping you. Even if you fill up once a week, you're only looking at $12 more a month?Get the car, put the good gasoline in it. Lifes to short to be cheap.OK, went to Acura site, it says recommended 91+ octane, performance lower when using lower octane. So this vehicle has a knock sensor to delay when the spark plug ignites ( retard spark). You can put what ever gas you want in it, it will just reduce performance but not harm the engine
