I want to buy an '07 Acura MDX, but refuse to be forced into premium fuel. What are the risks of using regular

I like the new MDX, but do not want to be tied to premium fuel. Is there a way around this requirement to use premium gas?|||use regular gas at your peril.





Using regular gas can cause pre-detonation in the engine, which will make the engine run hotter and could eventually cause severe damage to the engine. Basically the octane in the fuel stops the fuel exploding prematurely, ie before the spark plug goes off. Using low octane fuel will burst into flames before the piston reaches the point of combustion, when the spark plug goes off.





You would be okay now and again but if you fill up with regular then dont go thrashing it.|||Again, if the manufacturer specifies premium fuel, use it - for optimum performance and fuel economy.





You can fill it up occasionally with the regular stuff, but you won't get as good engine performance and fuel efficiency.|||No. If it says it needs premium gas, you pretty much have to use it. The car needs the higher octane rating in the fuel.





I'm pretty sure it'll run on regular, but you will see engine problems. I'm not exactly sure of the consequences, but I do know that they're not good.





But many a times, if you can afford the car that takes the gas, you can probably afford the gas too. Sometimes just not "eating out" at that one restaurant a week can cover your gas expenses. Ask any college student: pizza... or gas... hmm... hah.





My two cents,

If you want something that takes regular, get something like a Pilot or CR-V.|||decreased fuel mileage and performance, definitely will be noticeable|||If it requires premium fuel that means it uses a higher octane reading. If you use a lower grade of fuel your computer will reset. Ultimately causing knocking in your engine, your fuel economy will alter and will not work as efficient.


I have heard that it is more probable to have engine sludge as well.


You can use a lower octane rated gas, however, these issues will become a negative factor in the life of your engine.
