Thanks for the analysis. I'd love to use this in my FA20F when my car reaches 60k miles and is no longer under warranty. The only problem is that it only comes in a 1 gal (4 QT) jug size instead of 1.25 gal (5 QT) or 1 QT bottles. I end up buying extra oil anyway to fill my engine up to 5.5 QT...

Originally Posted by WRX12tt Your copper spiked quite a bit higher than mine. Glad to hear that it doesn't seem to be a huge concern. Your UOAs on GF-5 oil look good, any track time or extended spirited driving with some high oil temps? No track time or autoX. The only "extended spirited...

I've had that weird copper spike too, although at 27k miles. I've read that it is quite common, but nobody knows why...for what it's worth, it seems harmless. Here's my data: https://www.bobistheoilguy.com/forums/ubbthreads.php/topics/5035185/

Is there any data on: 1) Oil spec ? 2) Price ? 3) Ease of obtainability ? 4) TBN ? If i had to choose one based on the above data, I guess I'll go with "Oil A" simply because it's the first choice and my horoscope today says that I should be impulsive and make quick decisions when the moon is...

Originally Posted by FA_WRX My 2015 WRX has never had oil temps above 212ish F. from what I recall. Generally during open highway driving. Similar for me. In the winter, the oil temp gauge's highest reading was 209 F (98.3 C) and that was in 3rd gear at 5.5k-6.5k RPM with ambient temp of 30F...

Looks like PUP's additive package has finally caught up with every other SN+ oils. Lower Ca, and boosted Mg. Elemental analysis is not that much different from regular Platinum now. https://www.bobistheoilguy.com/forums/ubbthreads.php/topics/4573299/1 .. or any other SN+ oil.

I own a 2016 wrx, same engine as yours (FA20 DIT) and live in New England (so it gets cold here in the winter). My first two oil changes (6k and 12k miles) were free from the dealership, so it was the Subaru 5w-30. From then on, I've used Pennzoil Platinum exclusively (but I have no doubt other...
