i dont know if i would change the fluid that often...probably wouldn't hurt but the fluid is supposedly made to last 15-30k miles i believe...its your car and up to you...changing that often though may wear out the drain plug
as far as the power flush goes i thought it was a great idea....til i did it and my tranny went...a few others i believe have had trouble show up after using the powerflush...the suggested way i've heard to do it safely would be to drain, fill...drive for a short time or a day or so then drain and fill again
whatever u do dont let jiffy lube touch it
