My wife's daily grocery getter. Some short trip, some highway, nothing unusual. Used the Subaru oil because she got a coupon for a cheap synthetic oil change at the stealership. Blue Subaru oil filter and OEM air filter.
The universal averages may include cars with low mileage that have very high Si during break-in, which would push the average up. UOAs on the factory fill on Subarus are typically 200-500 ppm. I'm not sure if Blackstone includes these in their averages or not.As Javier pointed out the silicon is higher than what you'd typically see but the universal averages shows it is perfectly normal for these engines so no worries there.
They say they do not. They only include "healthy" reports from engines that are past break-in. This was a question they answered on their podcast.The universal averages may include cars with low mileage that have very high Si during break-in, which would push the average up.

Proven by only one Blackstone UOA? I wonder why Subaru Japan allows up to Euro 0W-30 in the FA24DIT and even 5W-40 in theMy long term beliefs that heavier oil produces less wear than lighter oil has been proven to be incorrect in Automobile engines. I used Mobil 1 oil in my '22 Forester and '18 Forester Turbo. I will be going back 0w20 IN BOTH EVEN THOUGH 5w-30 IS RECOMMENDED FOR MY '18.
Hardly. Changed my mind in the last 6 months.Proven by only one Blackstone UOA? I wonder why Subaru Japan allows up to Euro 0W-30 in the FA24DIT and even 5W-40 in the
FA20DIT?
People post things they don't understand and make completely unwarranted conclusions from them all the time. This is no exception.Proven by only one Blackstone UOA? I wonder why Subaru Japan allows up to Euro 0W-30 in the FA24DIT and even 5W-40 in the

If you are referring to me (which you may not be ) You (should) know. It takes me a while to change my opinions.People post things they don't understand and make completely unwarranted conclusions from them all the time. This is no exception.
Yes, there have been a few times I’ve worked with the owner, Ryan, on gathering several hundred samples for a given engine, and he told me that they filter out “known” failures and severe outliers. When I got the raw data I did a similar thing, and excluded any data points that were >3 sigma from the centerline of the data.They say they do not. They only include "healthy" reports from engines that are past break-in. This was a question they answered on their podcast.

My UOA'sHow is this being determined?
In your “oil is oil” thread you state you can’t differentiate one oil brand from another of similar approvals. But in this thread you claim you can differentiate a 0w-20 over a 5w-30 of similar approvals. I’m a little confused…My UOA's
