Subject: 40W oil causing wear problems over 30w?
From:
Interestingly enough, 15-40W is spec correct for both the mains and genset.
15-40W lubes a cold engine sooner upon cold engine start up than 30W or 40W
oil
does.
You can hear the difference.
While that maybe true, in this case we will not be seeing low ambient temps.
And if we were to, we would change the weight of the oil.
