The MY18+ Crosstrek has an FB20D; the previous gen (MY12-MY17) had an FB20B. The FB20D has DI and a higher compression ratio, among other changes.

The first UOA was the factory fill (see thread here), and the second UOA was the "Advanced Moly" version of Zepro (see thread here). Nb. that NAPA's contract lab continues to drop information that I filled in on the slip, including top-up oil added. The car drank more oil this time, about 1.5...

Is the built motor the original EJ257, a donor FA20F, or something else?

If it's of any use, I've got two UOAs from my '18 Crosstrek, which I factory ordered as you did with your '19: #1 (factory fill, factory Tokyo Roki filter) #2 (Zepro AM, blue Subaru filter) So far the FB20D seems like it's pretty easy on the oil, but then again I'm only going 6k miles between...

What's the deal with the engine nomenclature, btw? I've seen the same engine called the FA20F and the FA20DIT in different sources, and the OP listed both in his title. Did Subaru change their minds about what to call it at some point? The FA and FBs seem inconsistent generally - the turbo 1.6L...

They announced the new Legacy is getting the 2.4T in lieu of a 6-cylinder boxer as the upgraded engine option for MY2020. I believe it will be further de-tuned compared to the already-not-high-strung FA24 in the Ascent, but it's a twin scroll design like all the FA and FB turbos so it should...

I don't doubt that the Subaru OCI is very conservative - they switched from 7.5k to 6k at about the same time the early FB engines started having oil consumption issues. I don't know how close a kV100 of 7.1 is to the 'bottom' end of the 0w20 grade spec, but as you noted the TBN shows there's...

The previous OCI was the factory fill. No top-up oil was used during the first OCI (UOA thread for the first OCI is located here), while about 0.5 quarts were used during the second OCI. Oddly enough, dipstick readings showed the sump as being very nearly full until about 5000 miles in, when I...

I'm curious why some folks here prefer mechanical pressure gauges.
