Premium Fuel by autowrite

The use of premium fuel is used where it is warranted by the engines. If it's a high performance type or not and/or the manufacture states that premium is nessary to not deteriate the engine. Using the wrong octane can damage the injectors.
The Society of Petroleum Engineers has more information.

What does the octane rating of a fuel have to do with the injectors? The octane rating only affects the detonation of the fuel within the cylinder due to compression ignition, also known as engine knock.
 
I would also suggest that you use the spell check before posting message.

I suggest you read up on using the proper octane before you start making claims too.

Thank you for your concern with my answer. Now if you would care to explain what I said that was wrong I would appreciate the information.

On the base engine the fuel injectors are in the intake manifold so using lower octane fuel will not harm them (but poor fuel quality might plug them up).
 
The fuel injectors on the direct injection V6 are located in the cylinder and lower octane fuel than recomended can cause knock, which may harm the insides of the cylinder including the injectors.

Im glad i am not the only one to have had the fuel pump replaced. Parts are hard to come by right now. They took the fuel pump from the Loaded Red CTS In inventory rather than hold me up for 10 days. I get nothing but compliments on the look at of this car!!!!. The performance package with the 18 inch wheels make this car look complete.
