I own a 99 Subaru Impreza 2.5RS.
It currently has 154,000km
The recommended OCI is every 6,000km
90% highway mileage day-to-day basis for work.
With little short runs on the weekend.
Currently using CarQuest Premium Filter"WIX"
Using Amsoil Synthetic AMO 10W40. Seems the car feels better with this oil.
I tried using Castrol GTX 10W40, and the car felt sluggish.
It was a night and day difference when I switched to Amsoil.
So Am I ok with this Amsoil and Filter?
What OCI would you recommend?
An oil analysis kit was order a week ago, Hopefully I should receive it soon. I would like to see the Amsoil results.
