What kind of Acura?
Yes, I have a 2004 Acura TSX with 45,000 miles on it. I used regular gas when it was $4.00 a gallon and I got worse MPG by about 3.5 and the engine was "spark Knocking". Hope this helps.
Yes, this vehicle requires the use of Premium Fuel. The use of Regular will eventually do engine damage. You bought an Acura, and should have known that a vehicle such as this requires Premium fuel.
Take it out and put the new one in.

if its regular gas
Yes, you can use regular unleaded gas in an Acura MDX, but it is recommended to use premium fuel for optimal performance and fuel efficiency. The MDX is designed to run on premium gasoline (91 octane or higher), which can help maintain engine performance and longevity. Using regular gas may lead to reduced power and fuel economy. Always refer to your owner's manual for specific fuel recommendations.

Regular.
Put gas back in it.
Never put gas in a diesel car. And never put diesel in a gas car. An engine is built to handle one and not the other.
