The 2019 INFINITI QX60 3.5 liter V6 engine is equipped with 5 1/8 US quarts of 0W-20 motor oil. Oil and filter changes should be scheduled every 7,500-10,000 miles or 12 months if using fully synthetic lubricants, or every 3,000-5,000 miles or 6 months, if using conventional oil. The advantages of using synthetic vs conventional products include better lubrication among moving parts, a longer interval between service appointments and enhanced effectiveness under adverse weather conditions. An oil with a thinner viscosity like 0W-20 moves more easily in colder temperatures, coating engine components efficiently and providing better protection against friction and corrosion. Cost for a lube and filter job for the QX60 ranges between $150-$165 in parts and labor.
Not to follow maintenance schedule to change oil. The only thing she can flight against in this case is that the oil change reminder has never lit. Win or lose all depends on if there is a proof. It's going to be a tough case.
Is this a QX60 by chance with the VQ35DD engine? This engine was put into production starting in 2017 in the Nissan Pathfinde, Infinity QX60, etc.
If it is, this has got to be around 10 instances now where I've heard of this specific engine smoking like a chimney or sludged up to the point the only way to fix it is replace the engine. This is happening at low mileage as well, but I think 20K miles is the lowest I've read of yet. Most of the others were in the 30-50K mile range, but those folks at least did some oil/filter changes. If she indeed never changed or checked the engine oil in ~3yrs/20K miles, that engine, regardless of what it is, is probably toast.
I own a 2019 Pathfinder with this direct injected engine and I do know it blackens the engine oil quickly. I don't use the recommended 0w20 oil and I don't do 5000mi OCIs. I do them no later than 3500mi and I use 5w30 synthetic.
2019年买了一辆全新的日产SUV，只开了21000迈。 2021 年九月在dealer 那里换了机油。上个星期突然发现车后的排气管在起动时有蓝烟冒出后面检查一下，发现机油没有了。就自己加了一点机油，然后冒烟的情况就没有了，后来我们送dealer那儿去换机油，结果他们跟我说我这个车的发动机需要换.应为sludge严重。 不能flush。
这个车在卖给我们的时候维护提醒没有设置。所以换机油的灯从来没有亮过。因为这是我们家第一辆日产车，所以我们不太了解，我们以为还是像丰田或者是本田的车都是自动设置好的，到时就会提醒我们要换机油。 我们和dealer说他们卖的时候为什么不把维护提醒turn on。他们说是turn on 的。任何人都可以turn off。 说可能是我们不愿意看灯亮所以turn off。 这个车还在厂家的4年保修期内。
这两天我是气得睡不着觉。诚心请教大家。我们这种情况（新车维护提醒没有turn on）有没有地方可以申诉。 我们有没有什么办法能降低我们的损失。
我们已经向厂家提出修理申请。但由于我们没有按厂家要求的时间及时换机油。所以厂家很可能不会理赔。
建议你先到其他地方去flush一下。或者用机油多换几次。看看到底是不是引擎有洞了。然后再决定策略。
原来发动机里面的可能不是合成油。
因为还在保修期内，可以谈一谈，如果Dealer不全付试一试看看能不能付一半。
如果Dealer不付可以2000换一次合成油，换几次后也许会好一些，也许可以开下去
因为只有2万迈不建议flash；勤换合成油试一试
第一，service reminder 决不会卖给你时会 off的，唯一能reset的时候是它亮了的时候，谁给reset了你得审问拿过你车钥匙的人。
第二，机油少到一定程度油压会低到触发油压灯亮，你这里面的机油早已旧到成了油渣完全没有流动性了，发动机干摩擦都不知道摩了多久了，不死也半残了。
不看随车手册又一例。
因为Delear的利益不一样
我的RAM1500油压传感器需要换，保修刚刚过了两个月；Dealer开始说不行，后来他们和总部沟通同意了；
首先任何车厂都不会set to off. 就算真的off了她能证明吗？
你的车还在保修期，dealer不想用清洗（flush）的方式以免有后患说不清。你可以去普通有信用的车行，每几百哩或一千哩勤换几次，也可达到清洗作用。
是谁让你在一万三的时候第一次去换油的？在service reminder不会亮的状态下。
要修那东西就等于大修发动机了，怀疑有谁会替她修，不修就一直烧机油而且只会越来越严重。
她不说了她先生看到机油盖上有泥巴吗？那就是油泥，就是她的dealer说的sludge，所以人家也没骗她，第一次的油一万三才换的就算是啥神油都成油渣了，她这车从那时起就已经大伤筋骨了，后来那换了油的8000不过是压死骆驼的那根稻草。
悲剧一场，拉下帷幕吧。
理论上完全说不过去，叫你去换油是让你去给dealer送钱，没有车厂会不提醒你该去送钱了，我的Infiniti 只去过一次dealer他们就准忘不了email 我该去维护了，尽管我全都DIY.
我的是07，还没有service reminder.
的记录显示的 $199 换机油。 这家车厂的人看着特别懒散。可是这次换机油他们说只要65. 我们也懵了。那上次为什么是199 呢？

J是made in Japan. 日本人的QA比谁都严格，所以oil change reminder给调灭了更说不过去，除非是故意的。
合成油换油间隔：every 7,500-10,000 miles or 12 months
普通油换油间隔：every 3,000-5,000 miles or 6 months
楼主第一次换油是13000mile，里程超标。
车是2019年买的，没有说月份，第一次换油是2021年9月，至少21个月了，时间严重超标。
而且还是Street里程。
一辆车给你灌上个至少一加仑的合成油就多花了几十块，一百万辆就多花了几千万了。
还能开吗？如果还能开，问题应该还不算太大。

就算oil change light 不亮这么多的油泥也会触发了low oil pressure light.
居然没一盏亮的，难以置信都。
看看oil change reminder 是不是disabled 掉了。
It only takes one thing to void your new car warranty by any dealership: failure of performing maintenances required by manufacturer.
You can argue how many tens of thousands miles a super magic oil can last with them all day long, but they will never buy it.
都是全新买的，一辆02 Camry, made in Kentucky, 不到一年valve cover seal漏，另一辆 2016 Accord, made in Ohio, 新车机油多加了六七百cc，空调冷媒却没加夠，从来都不夠冷，去dealer查还说正常，直到我自己再加了几个安士才夠凉。
这个要看手册，不看你用什么油。
我用的滤清器，合成油专用，标注着 20k mile protection。
不信你去问厂家，肯定不会承认他们的车能坚持15k才换油。
里面的油都成油泥了，早就没了润滑功能了，valve stem 已经磨损漏油了所以才会冒蓝烟烧机油。
新车头几百公里是磨合期
