One for Bruce and Mola.
How comparable are Industrial gear lube specs with Automotive ones ?
Would this particular lube (Alpha SP220) http://www.castrol.com/liveassets/bp_int...ange_eu_tds.pdf go the distance Ok in a centreline spiral bevel and a hypoid diff ? (both require xW-90 lubes, and at least the 220 meets that)
Is there enough anti-foam/silicon in an industrial lube for diff use ?
Do the EP levels meet/exceed GL-5 levels ?
thanks.
