Oil Analysis Thread
Here are some oils that have been shown to show the best protection for the VQ35DE based on UOA:
Amsoil 0w-30 (great protection and good for extended change intervals 10k)
Pennzoil Platinum 10w-30 (second best performer, not good for extended change intervals like other synthetics, change at 3k)
Schaeffer's 7000 5w-30 (best overall protection, recommended for the DD, not for track)
Mobil1 0w-40 (good performer, works for FI and NA, extended change intervals 5-7k, also great for all climates)
Castrol GTX 5w-30 (outperforms many of the synthetics even Mobil 1 5w-30, good for the DD who doesn't mind changing oil every 3k)
Castrol Syntec 0w-30 European Formula (hard to find, usually found at Auto Zone, great performer, 7.5k change intervals)
I did not make this list. It was compiled by a member (Resolute) at My350z. It was made after analyzing many different UOA from the VQ35DE. It is not intended to be applied to all vehicles, it is specific to the VQ35DE. It is not a comprehensive list. There are still oils that have not been analyzed yet. There are some, however, that have been analyzed are did not make it to the list. Most notably Mobil 1 5w-30, which is probably one of the most recommended oils. The 5w-30 is not bad oil, but it doesn’t protect as well as any of the oils on the list and it’s expensive. Also, Royal Purple has not shown good results and did not make it to the list. There are some very expensive boutique oils, such as Motul, and they have shown poor results especially when you consider how much they cost. Don’t get caught up in the marketing hype of boutique oils. If you really want to know if an oil is doing it’s job then get a UAO.
