Well, now i really AM confused, the Bolens ST160 manual lube chart (p1-14) says to use SAE EP90 1.3 litres and to check the resevoire every 25 hrs ??!?!??! WTF What reservoire. only one is on the hydro pump on mine. and to put 1.3 litres in there i will have to lift the mower on its back legs or take the hydro pump off, doesn't sound right to me. hmmmmmm, thought this would be easy.
