ALWAYS change your filter with each oil change and I personally never go over 3000 miles between oil and filter changes. It is the cheapest insurance for the health of your motor. Use the oil weight specified in the manual too.jfairladyz wrote:i got new wheels 19 by 8.5 in the front and 19 by 10 in the rear. i want to know what is the biggest i can go with tires that will fit and lok good. also i want to know about the oil filter on the z33. do u change it every time u do an oil change. i went to this shop to get my oil changed and they told me the car has a filter that doesnt change.
