Posted: Thu Nov 25, 2010 10:38 am
I just changed my oil [V6 automatic] LE 63,000 oringinal oner miles on it .I used penzoil 10x 30 weight and for the first time changed to Castrol regular oil 5x30 weight ,its recommended all over the owners manual to use 5x30, I also use only Nissan oil filters ,when I parked in to drop the wife off I noticed a slight dampened knock sound on the right engine bank for the first time, it goes away when you ride or rev it up a little. I used my stethoscope and couldn't really hear any unusual noises from the top of the engine, could it be a bad filter or a knock sensor? or whats your opinion.
