Below are the AMSOIL oil and filter recommendations for your 2010 Subaru IMPREZA with the 2.5L 4-Cylinder.
2010 SUBARU IMPREZA 2.5L 4-CYLINDER ENGINE CODE EJ255
Your 2010 Subaru IMPREZA packs the 2.5L EJ255 turbo boxer engine, the version of Subaru's flat-four that made the brand famous in the performance world. Turbocharged boxers have powered rally cars and street legends alike, and they respond better to premium oil than almost any other engine type.
The EJ255 runs elevated oil temperatures under boost, and it is sensitive to oil condition. Subaru's own community is disciplined about oil changes for good reason: the turbocharger bearings, the ring seal, and the valve train all depend on oil that has not broken down.
AMSOIL Signature Series delivers the high-temperature film strength a turbo boxer needs, with a robust additive package that keeps working through the full drain interval. This is the oil to run if you drive the IMPREZA the way it was meant to be driven.
The 2010 Subaru IMPREZA 2.5L 4-Cylinder requires 5W-30 full synthetic motor oil. Capacity is 4.2 quarts including filter.
Here is what you need:
You need 4.2 quarts of AMSOIL Signature Series 5W-30 100% Synthetic Motor Oil ASLQT-EA which you can learn more about here: AMSOIL synthetic motor oil 5W-30
You need the AMSOIL nano fiber long life oil filter for your IMPREZA which is: EA15K12
