OEM filters all around.
New engine was because I didn't know jack about oils or turbo engine maintenance and was driving a Corolla before that.
I never checked the oil levels and was enjoying the power increase from the Corolla. Little did I know the M1 5W30 went way below the dipstick levels between oil changes. I just happened to check it one time around 40K miles and there was no oil on the stick at all. Unknown how often this has happened the previous times. 10K miles later.. tick tick tick tick...BOOM!
