In the manual for the S it specifies, "A brand name Hypoid 90 Gear Oil to API class GL5" .... In the little service booklet it says 80 / 90 or 90.

So going by the proper manual and knowing the S's reputation for the bevel box spitting it's dummy out, I thought I'd change the gear oil for something decent. It's got shitty "Carlube" stuff in there at the moment! (it's only been in there for a couple of weeks)

I've spent best part of today trying to find Castrol Hypoy 90 and nobody local sells it. I can pick up any amount of cheap crappy stuff, but Castrol, Shell, Mobil.....Nope!

In the end I turned to the trusty internerd and found this place

They take Pay Pal which is handy!

I've used both of these with good results:

Castrol MTX Synthetic EP 80/90:

Mobilube 1 SHC 75/90 Fully Synthetic:

The Castrol stuff is generally available off the shelf from Halfords, in the Motorcycle section.

Halford no longer sell Castrol or any other EP90 gear oil...it was the first place I tried. TBH knowing the R1100 / 1150 reputation for self destructing it's bevel box, I'd rather stick to the heavy 90 oil as specified by BeeEm. Synthetic is just too thin and the oil changes too infrequent for my liking. The box only takes 1/4 litre of oil and even after only a couple of thousand miles it gets pretty contaminated. It's usually the large single wheel bearing which fails first - I believe - due to small particles from the wearing process of the hypoid gears getting into the bearing. After a bit of reseaching and talking to 1100 /1150 owners who have had bevel box bearing failure it has always been the case that the oil has never been changed. Where it has been, the wrong grade or poor quality brands of oil have been used. ..........or the bike has been serviced by the dealer!!

Darth,always buy my ep90 from halfords....trust me;i go through a little bit of it!

Asked 'em last week at my local store in Wigan and again yesterday at the Warringtion store. They've stopped selling it according to the sales staff there, they only do EP80/90 and EP70/80 now . I can only assume that if you're still getting EP90 there it's old stock not yet sold......or the sales staff up here are the usual useless a'holes and can't be arsed ordering it!

You could try your local H0nda dealer

I bought my gear oil from halfords recently it's packaged as GL5 IIRC.
