Oil Filter compilation

[KyleWI]

Kinda what I'm thinking... Change the solenoid periodically and still realize the efficiency benefits when just cruising. How hard was it to remove? Sounds like it should be pretty easy, but I've never looked/tried (I will next time I'm due for an oil change).

RaceBox told me not to worry about it when I got tuned as long as I run quality oil and change it more frequently than the factory 10k mile interval. They said their experience with failures has been on higher-mileage used Q50/Q60s that come in.

From what I hear, MT is easy, Auto is a pain.

Good to know. With my car technically being 5 yrs old next spring, may not be a bad idea to pull it to at least inspect. It sat around most its life until Nissan finally sent it off a year ago, when I picked it up @ 550 miles, which is when the warranty clock started ticking.

I did not personally replace it. Fortunately, I have a very capable technician to do that for me. I don't know exactly how long it took him but he charged me one hour for the job on an automatic. He did the oil change and solenoid at the same time.

As I sit here thinking about things, I may have figured something out...

All the Q50/Q60 failures you hear about are around the 60-80k mile range, which is also when you hear of the factory turbos going bad. Most the guys modding the Infinitis seem to be buying them up used before clapping them out. Chances are they were owned by IT bros and Karens getting only the bare minimum of dealership oil changes every 10k miles. What oil(s) are the dealerships using? Unknown brand syn or syn-blends that meet the bare minimum Nissan spec? Dealers have also proven they'll use the incorrect filters with wrong bypass pressure, which in Nissan's words will send dirty oil to the turbos. At 10k mile intervals, I see this being likely as filter media gets loaded.

My new theory is that its these sludged up solenoids taking out the turbos as well, with the incorrect oil filters likely exacerbating the problem.

For us enthusiasts running top-quality synthetic oils with more frequent oil changes at <5k miles intervals, I really don't think there's anything to worry about, which aligns perfectly with RaceBox's comments to me.

Racebox wrote the same thing to me. Said @ 5500 miles not to worry about it. If something were to go wrong (in the future) car would go in to limp mode. Of course, being the paranoid type, limp mode is something I'm trying to avoid. My next move was to purchase the block off plate. You might be right about the Karens and the IT Bros. but isn't GM running into similar issues on their new engines? All of this just to appease our MPG overlords

GM's issue is poorly machined and undersized crank bearings. Before that, it was failed cylinder deactivation lifters and valve springs. Their BandAid fix was to move from 0W-20 Dexos to 0W-40 Corvette oil, but that solved nothing and the failures continued. Just this week they already released yet another notice on the warranty replacement of 2027 model year V8 engines. Add in all their 8-speed, 10-speed, & DCT transmission issues, and there is not a chance I'd touch another GM vehicle. Just ask Mary Barra (CEO), GM is no longer primarily a vehicle manufacturer, they're a data collection & marketing business.
