I was wondering if someone can confirm that the newer Synthetic Lower Unit oil is ok in some of the older motors. I recently purchased OMC - HPF Synthetic Gear Oil from my local dealer. He no longer carries the older "Hi Vis" oil. I noticed when I filled the lower unit it is much thinner in consistency. Any comments ?
