    Yeah, like a Noack of 30 to keep the valves clean. And since Subaru/dealers feel it's ok to way overfill the engine with oil, we wouldn't have to add any! Patent that idea Okie!

    Some super high performance engines have had water injection systems. You could install one of those, and fill it with valve cleaner instead of water.
    2016 Quartz Blue Pearl Premium CVT.

    Personalized with:
    Interior: LED lighting, auto dimming mirror, dashcam, trim rings on climate knobs.
    Exterior: Window visors, pin stripe, side molding, RokBlokz mudflaps.

    Actually the water itself is an effective cleaner

    Has anyone researched Idemitsu oil? It seems to be formulated for GDI engines and is the Subaru OEM oil. I never heard of it before recently. I have used Mobil 1 for about 20 years in all my vehicles. But, all of those were port injected.

    The zepro medalist or the D1G2 version looks good, but personally I dont really like Subaru OEM oil. It seems a bit on thin side and the oil temperature slow to come down once it heats up.

    You are lucky, they dont sell that in this part of the world.
    The best we can get is Redline SI-1 and Techron, but the Redline is much cheaper for big tank.
