if you boil it down and step back for one moment. isn't is kind of absurd to think an engines longterm survival comes down to a type of oil filter used!

Yeah, as I've mentioned elsewhere, the Garrett turbos are made of glass, and the VR30 engine is made of tempered glass - both will break, just one breaks easier than the other.

5k OCIs, Valvoline ME 5W30 oil, and "big" Nissan filter - the engine internals looked great when Infiniti pulled the engine out of my '17 Q60 @ 33k miles on the count of a whistling turbo, which they judged could have contaminated the engine with metal bits, so out it went!

After the engine & both turbos were replaced, I quit while I was ahead and traded-in my Q.

Major League. Jobo was the idol that Pedro Cerrano prayed to, and he had a shrine for Jobo in his locker. I thought the movie was funny in a sophomoric way.

*Jobu. He is the reason for my turbo health.

You need to pour Jobu some rum to ward off evil turbo spirits.

Your Q50 is having problems - “Should have gotten a live chicken!”

I feel I have a false sense of confidence because I have a ‘23 Q with updated turbos. Are there any accounts of failed turbos and block issues past ‘21 (yet)?

my engine blew at 70K with the M1-108A filter...I know it was not the cause, but I have never used that filter again. I have been using the cheap wix filter which has great everything same filter I put on my Subaru suv. Blackstone says specifically my oil has great filtration at 125k on the vr30 engine...point is overthinking filters is fun but not productive. Worried about oil pressure? Get a gauge, it's what I did!

You guys are way overthinking bypass pressure. Again, it has absolutely nothing, zero, zilch, nada to do with engine oil pressure, other than rpm based pressure.

The internal bypass is about differential pressure, that means the pressure entering the filter must be greater than what's leaving the filter in order for the valve to open. That difference in pressure is the PSI rating that you see.

If you have cheap **** filter media that does not flow as well, you will need a higher bypass pressure in order to keep more oil passing through the filter, but this reduces flow. Synth media has a lot more flow capability than standard media. That means there will be less pressure drop by default. Because there is less pressure drop, you do not need as high of a relief valve because the filter is passing more oil through it, there is more flow.

The change to that filter is restricted to that filter specifically, not every filter that you will buy. Most aftermarket synthetic filters are Head and shoulders above OEM filters, which are on par with the standard offerings you see at parts stores. There is nothing special about an oem filter, literally nothing.

Using that filter is not going to prevent your turbos from failing, end of story. Stop wishing, stop hoping, that's just not going to happen. Look through the failure thread. There is nothing anyone here can do to extend the life of the turbos. You can baby the car, you can change the oil viscosity, you can change the oil more often, you can change your driving habits, and literally nothing will prevent failure. The issue is that these are little turbos that spin over 200,000 RPM, and they either don't have good QC or they are designed with more tolerance than needed. That is the failure, not oil, and certainly not a bypass rating on a filter.

Agreed. Racebox put out a definitive maintenance guide, why would the GTR oil filters and Wix equivalent be a problem? Just another issue of poor design on Nissan/Infiniti's part.

I've stayed out of these threads intentionally lol. It's all over the FB groups too. 9E01A is fine.

Oil filters and oil viscosities are a source of endless debate here. I stay out of them also.

theyre not a problem per se, but there are definitely other filters that both filter better and hold more contaminates while also have more flow capacity, all at the same time. while changing oil more frequently is never a bad thing, changing it every 3-5k is not going to stop a turbo failure. look at our failure thread for the evidence. that being said, no engine in history ever failed because the oil was too clean.
