No it's 0w-20. I just use whata the owners manual says. There's clearly a reason for the weight difference
But they can't "void" anything from using an aftermarket filter as long as it's equivalent/right one.As long as it is in warranty I would use the OE filter. Knowing someone who is a tech as a Subaru dealership here in DFW I know Subaru looks for any reason to void a warranty claim. I hear the stories. But you've made your choice with Amzoil so my point is moot.
Did the base plate and threads match? Sometimes there are some size consolidations.so the amsoil filter came in because on their website you just type in the make and model of your car and it generates the oil and filter you need. well the oil is wrong as it suggests 0w-30 and the oil filter is model# EA15K20. I went to change my oil today and the filter looks awfully smaller than the OEM filter on there already. it even specified 2.4 FA24 engine. but when i looked up the oil filter graph subaru isnt even on there.
OK, so, if I use FRAM's cross-reference for that filter, the EA15K20, it crosses to the FRAM PH9688, which does show the 2022 WRX 2.4L as an application:I couldn't get my drain plug out as the oil was still hot so expansion but just by eyeing it. It looks too small and I looked up the filter model on the website and i didn't see subaru listed
