Reka Valve Oil for Piston Valves

Reka valve oil was the oil supplied with the flugelhorn that I ordered, from the Thomann FH600 range. I assumed as it was supplied with the horn that it would indeed be well suited and this has proved to be the case. I can't compare it because I've not tried another oil on this horn (I use different oils on my cornet and trumpet), but I have no reason to switch and have just ordered another 2 of the same!
