Complete Oil Specifications
Subaru’s owner’s manual for the 2024 Legacy (FB25) says to always use SUBARU approved engine oil. If that isn’t available, it lists an alternative: 0W-20 synthetic oil with an API classification of SN, SN PLUS or SP with the words “Resource Conserving”, or ILSAC GF-5 or GF-6A (Starburst mark).
Engine oil capacity is 4.4 US qt (4.2 L) when changing the oil and filter. Subaru calls these quantities a guideline.
Can I Use 5W-30?
Only to top up. If 0W-20 synthetic oil isn’t available, SAE 5W-30 conventional oil may be used when you need to add oil, but Subaru says it should be changed to 0W-20 synthetic at the next oil change.
