Does anyone have any experience using the Honda 80W/90 Diff Oil which is in my 2005 S2000 at the moment (last changed at a Honda dealer)? When I googled the product it came up under a Honda ATV website! From what I've read Amsoil, Redline or Mobil 1 are the preferred choices.

I bought 75w-110 amsoil from the local supplier (kanata rims).

OEM is 75W90 GL-5. I guess to them 80W/90 is close enough so they probably just use that because its cheaper for them to order in bulk or something along those lines? 80W has a different flow rate at lets say -25 Celsius its thicker in colder temps so I hope you aren't driving it in super cold days in the Winter? Did they use synthetic and I hope it at least hope it has the GL-5 rating?
