Did my 1200 mile oil change today

[kevinbonds]

Question: is the built-in oil change reminder just a simple mileage counter or is it a more complex algorithm like GM's oil life system?

I'm at 3,500 miles and my oil has been changed at least 3 times already (twice by me)

I just did number three at 5900 miles

"The Oil Control System informs the distance to oil change. Never exceed one year or the following distance between oil change intervals: 10,000 miles (16,000 km) for the VR30DDTT engine"

It will illuminate when the oil life is less than 940 miles / 1500km.

They also have alerts for Tires too, not sure if that is disabled by default or not.

This post went off the rails.

To pour fuel on the fire, I change the oil in all my cars at 3k mile intervals. I did that on my BMW (versus the recommended 12k interval) and never had issues that plagued many other owners. I also have a Hyundai Accent with over a quarter million miles that has survived daily abuse from 3 high school drivers. The internals look "new" even now (I pull the valve cover off when doing the timing belt changes... the last one was at 240k.) No deposits or varnish. That's a direct result of regular oil changes.

Extremely long intervals for oil changes (10 or 12k miles) are partially suggested because newer synthetics don't degrade as quickly as conventional oil does (and most new cars are using a synthetic oil). However, the main reason for longer intervals is that it is a convenience factor to save the end user time and money (and "help the environment") The dealer cares that the car survives the warranty period. They have no interest in long-term reliability after that.

If a person is happy keeping the same oil in their crankcase for 10k miles (or more), that is their car and thus their personal choice. These are usually the same people that dump the car for a new model once the warranty is up or the car is more than a couple years old. I, however, will not be doing that. I make the monthly payment on this car and I am the one driving and maintaining it. I usually keep the same car for 10-15 years (and currently have 2 that I've owned for 24+ years each) As such, I will use my own best judgement and experience to care for my $40k+ purchase.

Love the car talk, and the ignore feature. Use it guys.

My 1993 Miata 240k miles oil changes every 2 years whether she needs it or not. My 2002 explorer is over 300k miles, faithful Walmart brand oil changes in my home garage every 10k miles with whatever filter is on sale, auto transmission has never been touched, no issues. My 2012 Ford Fusion, 220k miles, same deal. 2021 Explorer, 91k miles, same thing. 2022 Ford Escape, same thing, 68k miles.

2023 Sentra, 14k miles, has had 3 oil changes. Mobile 1

My Z, 6,000 miles, 3 oil changes, mobile 1, will do 3k changes on it just because I drive it really hard 10% of the time. I had done 10 or more launch controls before it had 50 miles on it, I have never done a break in on any car and have never had an engine or transmission casualty and none of these cars burn oil.

I also have never messed with a differential or transmission on any of these cars, all have original fluids in them, yes even the Miata. I have owned all these cars since new.

There have been other cars come and go, the Z is the first one I'm babying just because I'm older now and have the resources and time to treasure the car. I don't consider not "breaking it in" as abuse.

Wow! I'll spare the details on my reasons, these types of 'oil' threads always gets sideways. But changing oil is always cheap insurance IMO, every 5K miles with good synthetic is plenty sufficient. Oil formulations are very good nowadays. First oil change at 1K done, and just serviced the LSD with Redline 75W90 at about 2K. On with life....

I just did rear diff fluid at 5k miles and I cannot believe how dirty it was, and the amount of metal flake in the oil. I went with Valvoline 75W90 synthetic I could not find redline locally.

For future info, most O'Reillys stock Redline, but yes, the break-in sludge/shavings are nasty! I've done mine twice already just to fully flush it all out.

I was thinking I will run the valvoline for a few thousand miles to help clean it out then drain it and move to the Redline.

Perfect plan IMO.

From what I saw with the drained gunked up diff fluid, that looks more important to replace at sooner initial intervals than engine oil, only for LSD diffs though.

1st - 1,200
2nd - 2,670
3rd - 5,311

the reason - because i want to & can…

the manual is for folks that can not think for themselves…

it’s a bad - very bad assumption thinking the manual is controlled by engineering.

Marketing \ product management controls the manual.

competition, gas mileage, EPA, emissions requirements & gov. regulations are all baked into the manual…

I won't show you guys my hyper OCD anal maintenance logs...

Can't speak for others, but personally, I thank you for not sharing your "anal maintenance logs."

 

[Neutr0n]

Incorrect. Nissan says every 10k miles. I suppose you are smarter than a Nissan engineer?

do you also believe in santa clause and world peace?

FWIW, I changed the Engine oil 4 times, diff 3 times, manual trans 3 times. Blackstone keeps telling me to go further (I'm basing it off the number of track weekends) for every single one of the above.

Engine oil will now target 4 weekends, diff 8 weekends, and trans 8 weekends. I'll just keep doubling it until Blackstone tells me otherwise.

Additional info for y'all, the diff fluid AND manual trans fluid came out clear during the 3rd change. I'd highly recommend getting rid of the factory junk. I really don't see why Nissan "Requires" their formulation for the trans, but I've yet to have a problem with some motul 75w90 in the trans.
