Earlier
this weekend the recomendation for a startuo oil was for a mineral oil, 40W
minimum. Is a multi viscosity like a convetional 20W50 OK? or
should it be a straight 40W or 50W?
Thanks,
Joe
Joe;
Are you pre-mixing
2-cycle oil? I think the only advantage of a straight weight oil would be
if you use the metering pump injection as a straight weight may burn a bit
cleaner.
I used Castrol 20/50 for
about the first 60 hours with the injection system; then converted to pre-mix
and synthetic. The Castrol 20/50 is an excellent lubricant and served
well. It may be that the seals have seated in more since going to premix as I
seemed to have picked up over 100 rpm static over the last 80 hours. But
I think it’s common to get a peak in power somewhere past the 100 hr
mark.
Looking forward to
hearing about your first runs.
