Bar Oil

[Lnewman]

When cutting at a temperature around 40 degrees should you use summer or winter oil?

 I would use summer if I had it!

Just to throw a wrench into the works,I keep a jug on the shelf in my OWB to keep it warm in the winter time.   ;D  I do have some poulin oil that I brought at walmart years ago. When other places were $8 they was selling it for 5. That stuff is some thick. I still have a few gallons left, That stuff I only use in the summer months.

in the mid season- mix it half winter and half summer weight

You can use summer weight all year round but should not use winter weight in the summer. It is to thin and when it gets hot it will not stick to the bar very well. The only reason for winter weight is to make it easier to pour, it makes no difference in the saw.

Once the saw warms up, the heat from running the saw will keep the oil flowing very well at temps below freezing with no problems.

If it is considerably colder than freezing out, keep the jugs of oil in the cab of the truck in a 5 gallon bucket, so if the oil jug springs a leak you don't have nasty bar oil everywhere.

Make sure the bar groove is nice and clear and you should be good to go.

Good luck

I guess you guys haven't run a saw in Manitoba or Minnesota winters ;)
Out here we have heavy, medium and light. With a saw sitting overnight in -25 F or colder heavy summer oil will be petrified solid in the oil pump. Fire that saw up and you could take out the oil pump drive.

I can't say I have seen winter temps that low here, -25 F is an extreme thats for sure.

Do you leave your saws outside or in your vehicles at night when it's that cold?

All our equipment stays in an unheated, insulated shop, average temp is 45, so over nights or when we are not working, things are inside out of the elements, temp extremes are kept to a minimum.

I picked up a couple gallons of winter weight bar oil a few years back, still have not had a need to use it in our winters

Myself  as a self employed  arborist operating a tree service company, I can now afford to take the coldest days off. But back in the day when I was a logger on a company payroll I had no choice but to work those coldest days.
Back then winters were much colder for longer periods of time. -35F didn't stop us, run the saws and skidders 8 hr a day, at the end of the day bore cut the saw into a tree and go home. Next day 7:30 am again -35 below, pull the saw out of the tree and 5 pulls the saw is going again.
