Crawled under my truck this morning to do what I thought would be a routine, 20-minute oil change. First one for my Titan. Well, it was anything but routine. For starters, I discovered that the only way to gain access to the filter was to drop the front skid plate. No big deal; had to remove 4 screws and loosen two, and the skid plate was out of the way. I have a 4x2, by the way. So, I drained the oil and replaced the pan plug; no big deal. Then I went to remove the filter. Placed my trusty adjustable-jaw filter wrench on my breaker bar, and gave it a tug. The filter remained snug. So, I really yanked on the breaker bar, and my filter wrench lost it's grip and wouldn't break the filter loose. The danged filter was like welded on! Tried a huge pair of pliers. Nope. Finally had to run the filter through with a screw driver and beat on it with a rubber mallet to break the damned thing loose. Never in my life have I ever run across a filter stuck on good like this one. Put the new NAPA Gold filter on it-hand tight!!!-and filled her with Mobil 1. Now, the moral of this story isn't that I am b_tching about changing my own oil; I have done it for over 30 years now. I just want to let you know that when you go to change your oil for the first time, be prepared to fight the factory filter to get it off. I think some bonehead on the assembly line put the filter on without lubricating the gasket, and then torqued it to about 400 ft/lbs. As for dropping the skid plate, that was my choice. I could have done the contortionist bit by bending over the front of the truck and fighting for space with the fan blades, but I chose not to. Someone at Nissan did have a good idea; if you drop the skid plate, you'll find a small length of metal placed under the filter that acts as a drain trough when you break the filter loose. Saves making a mess and having oil all over the engine side of the skid plate. Anyway, I just wanted to share my experience with y'all, so that you will know what to expect.
