Engine oil MOTUL or AMSOIL

Amsoil is just an above average full synthetic oil. It's nothing magical. It has a higher than normal "Total Base Number", which is what allows it to go longer between changes without going acidic.

Motul X-clean efe for my 2016 WRX! 5w30. Hands down the best oil for the turbo FA20 engine.

I use Amsoil 0w40 or Eneos 0w50 in mine. For sealing and shear resistance for metal to metal contact, thicker is better.

I've had good results from Blackstone with running Motul X-Clean EFE 5w30. It has a high HTHS value so it keeps it's viscosity over time, from what I understand.

I run amsoil Signature 0w20.

Personally I use Motul 8100 Ecolite 0W-20.

I ended up returning the Castrol Edge 5W-40 and got AMSOIL European Car Formula 5W-30 Improved ESP Synthetic Motor Oil instead, which is VW Approved and 504 spec. Its quite pricey though, $180 CAD for 12 x 946ml.

Amsoil XL 5W-30 in my 2016. Swapped with a new OEM filter every 6K.

Oil and filter change, switched to motul 4100 15w50 (thanks Bernardo on the recomendation)

Been using motul 8100 eco
