Yamaha gear lube?
I changed the gear oil in my F150 last month. I noticed that there was a green/blue color oil that came out but the new Yamalube I put in wasn't the same thing. I checked the container again and it says for use in all Yamaha outboards.
Whats got me thinking is I read somewhere that the consensus was that Mercury premium was the best gear lube to use and that a lot of Yamaha tech's use and recommend that product. I just want to use the best product available for my motor. I'm wondering if I should change to Mercury Premium now, instead of waiting until the next scheduled service? If what came out of it was synthetic and I've changed to dyno, I need to change back to synthetic, now and not wait, right, or not?
