Here's a chart I started compiling from BITOG and other sources that may prove helpful.

Very curious as to the Pennzoil Ultra and Eneos VOAs . . .

 

looks good, but where's tho Mobil1? lol b/w Mobil1, Ester, Ultra and Royal P those seem to be the 4 biggest

 

Yeah it's a work in progress.

Based on the Used Oil Analyses I have seen, I've not been impressed with Mobil 1 in the VQ37 compared to other UOAs. Probably why I left it off - I'll never use it.

 

fair enough I've used it since day 1 and haven't had any problems but am thinking of switching to Ultra on the next change to see if there's any difference

 

Nice list. Hopefully you can add Eneos to it soon. I've captured the oil changed at 5309mi interval and another bottle of virgin samples. Haven't had the time to send them in, I blame it on USPS closing too early.....

Thanks bruin. Looking forward to it!

It appears that Pennzoil is phasing out Platinum in favor of Ultra. The Platinum VOA looks pretty good to me. Thin for good MPG but with a high flash point/Viscosity Index to stand up to the heat of the VQ37. And a stout TBN for 5K-7.5K OCIs.

Walmart has 5 qt jugs of Platinum marked down from $23 to $20.50, and there's a $5 instant rebate going on as well. $15.50 + tax for 5 qts of Platinum is a steal.

EDIT - Pennzoil is not phasing out Platinum. In fact, if you go to their Oil Selector page, they actually recommend using Platinum and not Ultra for the G37.

 

Dang... might have to swing by and pick up a few jugs... thanks for the info!

 

Bwahaha look at that moly in the 300V

 

makes me wanna go change my oil this wkend...never woulda thought to go with pennzoil tho...always went with mobil 1

 

yeah the Pennzoil Team is really stepping it up with the Ultra, it's either the Ferrari or Porsche race team that is their big marketing team now

 

Ive also done a comparison which includes some other oils.



I have the VOA for Ultra as a 5w20. Im assuming its the same additive package for the 5w30 with just different viscosities.

 

That's interesting. I wondered if the Ultra was too new to make their oil selection page, but then I tried a 2009 Corvette ZR1. They list Plat as the standard and Ultra as the Premium recommendation. Maybe they're going to push this as an upgrade for cars that already 'require' synthetic oil?

Or perhaps they just haven't done testing on Infiniti with it yet.
