Zack--

Do you think your engine is using the dual oil filter? I forget what year you put in your truck. They seem to have changed from the single full flow filter to the dual filter in '82 or '83. All of the engines that I have seen with the dual oil filter also had a stainless steel oil cooler whereas the earlier engines had a plain steel cooler painted black.

If you are using the earlier filter, that would help explain the good price from Nissan.
