I have about 25 miles on this filter and oil, Oil is Castrol gxt 10w/30 and the filter is a Wix. Current temps in Nevada are in the high 40's-low 50's during the day and close to 20 at night. I have been hearing a lifter tick noise for about 6 months and thought the oil change would help. It didn't . Thats when I heard the louder knock, and decided to try an additive. Now when I first start the Pathfinder up i still hear the lifter tick and the other knock seems to gone. After it warms up the lifter tick is gone as well. The motor is right at 149,000... Im not sure how it was driven in the past, but since I have had it it's been driven to and from work on the freeway.. But every now and then I do like to air it out.. But Im no street racer when I drive.
