Is it in any way unique? Or will any 2.5wt sus oil do?

I’d like to know also. From what I’ve read about the Reverb, the early versions came with a bottle of 2.5wt suspension fluid. Now, they come with a bottle of Reverb hydraulic fluid, which could well be their pink mineral oil, or it could still be the 2.5wt suspension fluid. Printed on the side of the post is ‘Reverb oil only’ near the bleed port. So it could be either. I suspect, RS want you to buy a tiny bottle of the expensive stuff and not a litre of the same stuff at the same price. So, in conclusion, dunno!

I’m going to take a guess that it’s Torco RSF Light (2.5wt), based on the fact that RS used Torco oils prior to switching to Maxima (and Maxima do not produce a 2.5wt oil).

Srub my last post!

Just seen that Maxima also produce Racing Shock Fluid in a ‘Light’ variant, so I’d guess it is this (again, based on the fact that all the Pitstop oils are sourced from Maxima).

2.5wt fully sythetic oil is fine, have motul in stock 😀

Also interested in this – as the bottles seem to leak when left on their side in the box, so I now have two Reverb oil-impregnanted cardboard boxes.

I’ve recently used just 2.5wt oil, worked fine. Then of course the typical air loss problem happened and the good guys at Fishers warrantied it.
