All of 'em have the HG hydros... either 2800 or 3100. Not much difference between the two, but their low oil capacity and high temps make me think REALLY good syn makes sense for those .... and $$$ doesn't matter to me. I have a 5 qt. Castril 20W50 on hand and two dinky China filters ... (HG branded) ... never used 'em on my baby Scag.
Motor Earl ... I'm thinking 20W50 from Mobil/Amsoil (with added ZDDP, etc.) or the syn Kawi stuff the dealer sells...
I'll get specs and info later and compare.
Need something designed for Z-Turn (air) verses auto earls....
Earl isn't earl no mo'
Thanks!
