How about another oil thread? Everyone drink up, open the windows, and piss off the neighbors.
Puch maxi. Stock clutch.
Switched from type F fluid to rotella t1 straight 30wt this summer and kinda like the grabbier clutch and extra smooveness (higher vis than type F seems to make the old gears mesh a little more happily). Reportedly...Rotella being a diesel formulation it lacks the "friction modifiers" anathema to wet clutch use. Here-say. Surely.
Draining it I think it looks dirtier than the used type F. And then i wonder. Could rotella be less friendly to the clutch pad composition? Who knows? I often wonder if anything at all out there that isn't specifically labelled "for wet clutch use" risks fkkng up the pads prematurely. But I have a few gallons of t1 laying about. And it's a moped.
I'll never learn. (edited)
