    I ended up getting the transmission fluid.
    By  Pat,  a  Verified Buyer  from  Ohio  on  June 08, 2019
    I initially ordered the transmission fluid and accidentally got the engine oil. After returning the engine oil and receiving transmission fluid signature series, I must say how pleased I am. I noticed the few MPG improvement after changing the transmission fluid which had 43K on it. The engine shifts through the gears more smoothly.
    Bottom Line
    Yes, I would recommend this to a friend.

    Peace of Mind
    By  Jeff,  a  Verified Buyer  from  Ontario, Canada  on  June 06, 2019
    When trying to go the full 8000km between oild changes typical synthetics do seem the break down around 6000km, You can tell but the return of valvetrain chatter even faintly after startup. I've noticed the Signature series holds up and I no longer hear that return as the miles / km's increase. Great Product!
    Bottom Line
    Yes, I would recommend this to a friend.
