They definitely don't.

So does anyone know which PureONE filter to use for the x sedan?

 

Amazon recommended me the 14612 for my year/model. According to purolator's site, the PL14612 is the size to use for all G37s -- coupe, sedan, X, base, sport. Some people have tried the 14610, which they say fits also, but that's not the "official" size to use. I guess the idea is the slightly larger filter may filter better, or last longer -- but personally I wouldn't want to risk the other size having some kind of unintended effect on the oil pressure or something like that. So I stick with the recommended size.

Again, PL14612 for the G37 and G37x sedans.

Ok cool... I couldn't find anything regarding the X. Thanks for the info!

 

Good call, I can have that site price match the price you're getting. Thanks.

 

 

So, how's it been running on the Ultra, OP?

 

So far so good for me at least. Should be going to the track in the next month or so. That should really but it to the test.

 

Don't use PU...

 

hmm interesting. Waiting for the oil experts to chime in.

 

Ouch. Others have posted good results with this oil.

I'm approaching 4,000 on my PU oil, will do an analysis as well.

 

I wish they would have been more specific and said what was better to use, rather than keep us guessing with what not to use. But I imagine they have some ethical obligations to maintain objectivity and don't want to recommend anything.

 

I agree with you shadowman. I did email them some questions and here is their response:

Rick,

Thanks for the email. There's a lot of confusion right now about Nissan's new 3.7L engine and the oil type needed. We are aware of Nissan's recommendation, and you can't go wrong by sticking with that, but it is expensive. For now, try going back to the Mobil 1 since bearing wear looked a lot better then. Also, I amended the report to include the TBN information. We would probably stick with 3,000-4,0000 miles on the oil next time to see how the bearings react. If lead is still high, try Nissan's oil once and see how things look. For now, the jury's still out on the type of oil this engine needs. Hopefully, we'll get a better idea as more samples come in.

 

I just mailed in my first Ultra UOA yesterday. I guess we'll just have to wait and see how it goes. Had about 3500miles on the oil along with one track day.

 

I recently mailed mine in too, Tuesday. It's with Pennz Ultra, right at 4,000 miles on the oil, 13K on the engine. Will post when I get the results.

 

I still have to send in my Motul 8100. I pushed it to 5k miles
