Just wanted to share a UOA. Been browsing this forum for years and finally got a UOA done on my 21 year old Maxima.
About the oil used: Typical 10w-40 Api SN Chevron Supreme. Car has mostly seem this and Pennzoil for most of its life.
This Maxima has 246xxx miles, original engine even with the original chain guides and tensioners. Oil has USUALLY been changed every 3k miles. Also, since ive owned the car since 194xxx miles...I have used mostly Fram Tough Guard oil filters as well as a 10w-40 oil.
Driving conditions on this oil run were somewhat severe. One 60 mile mountain climb, 100 degree weather running at 3500rpm 4000rpm. Mostly short trip city driving under 20 miles long, commute has lots of hills and im usually running the engine in 3rd gear. With AC running most of the time. Car still has its original automatic which works flawlessly.
For 246k miles I am extremely impressed with this car and this oil report. Its known that the nissan vq engine can be hard on oil but this oil held. The TBN was starting to get somewhat low but thats fine with me. I wont ever let my oil get past 3k anyway.
