In my chainsaw (Homelite), the season of the year wouldn't really effect the
weight of the oil. The oil tank is part of the alum engine casting. In cold
weather, the oil regular bar oil is difficult to pump, however only a minute
of engine operation has the oil warmed up and I'm then able to pump it on to
the chain guide.

I think 30 weight would be too light and wouldn't cling to the bar and
chain. I have tired it in a pinch and it seemed like I would have to pump
oil continiously while sawing.

I am a frugal guy but I won't skimp on the bar oil, knowing what a
replacement bar costs. They wear down fast enough as it is.

I second that. I have never seen anything in any saw manual that
recommends anything but bar/chain oil. Those oils contain anti-sling
ingredients that help the oil stick to the chain. I am sure that the
engineers who design saws and chemists who formulate the bar/chain oil
are much more knowledgeable about what to use than the user. This
discussion raises it's head almost annualy on any forum dealing with
saws, IMO it is nonsensical. Go with what the manual recommends.
