    Jeep and Subaru likes it
    By  JUSTIN,  a  Verified Buyer  from  Calgary AB  on  June 02, 2026
    I switched from the 0w-20 on a Jeep 3.6 and Subaru 2.4l turbo last fall, both motors sound quieter on start-up and when the oil is at max temp. I have seen no reduced MPG after making the change. On the Subaru turbo motor, the oil temps under higher boost/loads are 3-4C cooler and on the 3.6l it has a couple more PSI of oil pressure during low speed high load off road conditions.
    Bottom Line
    Yes, I would recommend this to a friend.
