Noticed my normal bar oil is awful thick this morning. Got into the negatives last night now like 10 degrees F’. I do have some winter blend at our other property. Is it ok to run the normal blend in such cold weather? Only for a few cuts. After filling the oil tank I set the saw in our heated shed to warm up so the oil isn’t as thick. That was a half hour ago. Haven’t cut yet.

B&C oil... :roflmao:

I never bought a single drop of that scam product on purpose!

But, I believe here where I am "summer" blend is rated at close to 200 (160-180 or so) in viscosity while the "universal/winter" blend is 100 or a bit over.
I rarely see the "winter blend" , supermarkets and hardware stores simply stock the "universal/winter" blend.
What do u use?

I started logging appx 45 minutes west of Minocqua ;) about 50years ago and never used anything but summer blend.
Some mornings I squeezed the thick oil out of the jug like STP additive which made it difficult to fill the oil tank, other mornings I remembered to put my bar oil down near the trucks floor heater before heading to the job site.

By the time you let your saw run for a few minutes to warm up the oil should have started to thin back out, a bit of cutting and the hot bar and chain will further warm up the tank and pump, 50yrs and never an issue.

If you are talking about electric chainsaws I have nothing to say on its use in winter other than batteries will need their own attention.

Many of the TSC have summer blend oil on sale right now for $5.49 winter blend is $19.99 ;)

I also wouldn’t worry about it. Like @IffykidMn said above let the saw warm up and the oil will flow out.

I use a mix of random things on the farm for bar oil and haven’t had issues with it flowing or not lubricating properly. When it’s below 10f I’ll put some used 5w30 (gasp) in the tank if I remember but it’ll empty the saw tank about the same speed as the regular mix of gear/motor/hytrans/etc that I use so I really don’t think it makes that large of a difference as long as the saw is warm.

Winter / summer bar oil is a sales gimmick for dumb peeps. Look in the mirror and who do you see ?

Everyone with more than a few brain cells knows what oil is and can look it up some is thicker and some is thinner (the word them guys with the white lab coats call viscosity @a given temp)

However, if you mix 2 oils of different viscosities it will thin the thicker one a bit. It’s up to you to fine the cheaper oil to mix. Or pay a premium for someone else to sell you something you don’t actually need.

how does one know if the thin one thins the thick one or the thick one thickens the thin one?;) 🥴

I guess if you got on the short bus to school, then it’s a good question to ask . But as you are actually asking that question. I guess you were on the big bus and can loogle it for the correct answer 😉👍 lol…

But the shortest reply I could think of… yes your correct…”you gotta be dumb if you can’t work out “

So ask yourself , my short answer and look in the mirror for the answer
😘

I just bought 12 gallons of Bar Oil at TSC in their description it is summer oil (thicker oil) I have a gallon about 1/2 full I have been using. The next day I go out to cut I will add a little diesel fuel to that jug to thin it out some. That is about a technical as I get. I too have poured oil many times when it is so cold the oil goes into the tank in thin ribbon like folds. I don't think that is good for the oil pump so, that is the reminder for me to thin my oil a bit. I have a diesel tractor, so fuel is always handy.

If you don't ever want me to borrow your saws, use transmission fluid....that stuff smells horrible. I hated when customers would bring a saw in that was not cleaned up and had transmission fluid all over it.

I thin 25% with kerosene in cold weather: this was a recommendation from Oregon (?), or in a manual from one of my saws.

I don’t like the small of diesel.

Corded electric and battery saws don’t have internal combustion to heat up the bar & chain oil. But, because they don’t contain mixed gasoline, I can safely keep them warm, indoors, or in the cab of a vehicle, until use.

I have used battery saws down to about 20°F. The same batteries are used to power ice fishing augers, etc. Just don’t charge them when frozen.
