which is it noob?

 

is the gas mileage significantly noticeable?

 

no i just feel the car runs smoother, and is really only worth it during cold winters when most engine damage occurs!

 

well any oil change in my opinion makes the car run like its just been tuned up. tell us how the oil is after 3,000 miles. if you had to add oil, if its really dirty on the dipstick. this is on a k series motor?
