Subaru Japan now only recommends two oil grades 0W30 and 10W50

[BDK]

Something interesting Subaru Japan now apparently only recommend 0W30 for regular cars and 10W50 for WRX STI's...I know in the past they used to recommend 5W30 and 5W40...

テクニカルデータ | LES PLÉIADES : Made for SUBARU Boxer Engines Best balance & Best protection

And the 10W50 not to be used in the F series engines FA20 FB20

Woooo! HTHS of 4.5! That’s not going to be “energy conserving”!

Up in the Japanese tree house a sign says no water oil allowed.

JDM lol…a place known for its high quality PCMOs

That rock crusher they call an engine in the STI probably does need 50 weight. Everyone was running Rotella T6 5W-40 when I had my legacy GT with the EJ255 because the engines didnt like 5W-30.

A 0W30 with a KV100 of 12.18 cSt
And a HTHS of 3.5 cP

For a halo performance car that maybe one in a thousand sales...

Yes, but also a very high PAO/Ester content based on the -57.5 PP...

Anyone have a price point on this?

i guess...not meant for a typical mama-taxi to drive the kids 2 school...
unless that mom likes to drive in helmet and racing suit.

I wonder how many complaints about oil burning would go away if Subaru would spec the right oil for their US cars.

In my country Subarus dosent have oil burning issue like the US have... so complaints would drop.

What a weird name for oil.

Interestingly the 10W50 is different than the regular Total Quartz racing 10W50...that or the pdf wasn't updated (2014?).
