Bel Ray Gear Saver 90w GL-5. Matches the Honda specs and available at most motorcycle shops.

 

Anybody use the amsoil 75w90 gear oil? Haven't heard much about it, but i know amsoil makes quality motor oil so i assume the amsoil gear lube would be pretty decent as well.

Also, I just noticed amsoil makes a "severe gear oil" in the 75w90 weight, perhaps that would offer more protection for our diffs? Anybody tried it?

I am talking about the differential too.

The following is taken straight from that link...

Diff Oil: Straight SAE 90 Weight
I use Mobil 1 75w-90 personally. I know many like LE 607, but there are 2 key things to keep in mind. LE 607 does not have the "official" API GL5 certification, so if you use this, and you suffer a diff failure, don't let honda know you used this fluid as they can easily void your warranty.

Secondly, LE607 is NOT for use in cold weather. No straight 90w diff fluid really is, as they tend to have higher pour points than say a 75w90. NOTE: LE 607 is been replaced by LE1605

1) LE-607 is GL-5 rated. Honda cannot refuse a warranty claim based on use of this lubricant.
2) LE-607 is not for arctic use, but it has a rated PP (pour point) of -11 degF. That is the lowest PP I have seen for a 90w gear oil.

 

Amsoil 75/90 severe gear oil here. I have been using it for 2 years now. Heavy duty stuff go to amsoil.com for more info.

LE1605 here

 

How can you tell if the diff is notchy in cold?

"LE 607 does not have the "official" API GL5 certification, so if you use this, and you suffer a diff failure, don't let honda know you used this fluid as they can easily void your warranty."

"1) LE-607 is GL-5 rated. Honda cannot refuse a warranty claim based on use of this lubricant."

say what?

I've been running 607 for two winters now in new england. it works fine at the temps we see here. I tore it apart after winter 1, and everything was in tip top shape.

 

Im not saying that you cannot use it or it is bad. Im simply saying that the LE is thicker than say the mobil 75w90 and it needs more time to warm up.

 

i noes. i baby her for 1st ~10 miles in the cold just to be safe.
