I've owned this used car, but I don't know well about the cars.

I've three questions. If you guys know it, plz tell me what I gotta do.

What kind of gas should I put for 03 accord Ex V6 regular, super, supreme?

I went to dealer to get wheel alignment, but they didn't do it, cuz they told me my front right wheel got bent.
Is it a big problem? Does anyone know how much it cost to fix it?

Whenever I drive, brake, and only turn to right, I can hear the sound skretching like KKi~~~ from back wheels. Also the sound is not constant. Sometimes the sounds appear, and sometimes it doesn't.
anyone know what happened?

If you know it, Plz plz tell me...

 

As far as the fuel goes... regular is fine, anything more will only hurt your wallet and do nothing for performance... however the higher grades of fuel do contain more detergents and additives... so but what you like.

The alignment : First off, why do you think you need an alignment? Does the car pull one way? Is the steering wheel crooked? If you have bent parts.... wheels, suspension parts... they must be replaced before the alignment can be set.

Noise: Now it's difficult to tell what could cause a noise without hearing it, but i suspect that it is the rear brake pad wear indicator contacting the rotor. When the brake pads wear down, there is a metal piece that is designed to contact the rotor and cause a screeching sound.... so that you take it in and replace the brakes before they completely wear out.

 

when I go straight, the handle is not straight.
It leans to left about 10~15 degree angles.

I'm not sure which part got bent. they just told me the wheel got bent. That's it.

Thanks for participating with my questions.
Thax alot.

 

The car definitly hit something and bent some parts... have a good shop take a look at the suspension and see if they can fix it.... not cheap, but necessary.
