Chain Saw - Chain oil

Some guys I know who do a lot of chainsawing don't buy the expensive chainsaw oil but go to Bookers Cash and Carry and get a 25 litre can of vegetable oil to lubricate the chain . Big saving.

i've heard about that as well, does it do the same job i wonder. I bought a new chainsaw last summer and i think i'll stick to the proper stuff

Ahhh The amount of dangerously worn and ***** chainsaw chains that I have seen because people have taken the cheaper option.

Chainsaw chain oil is expensive for a reason; It's designed, engineered, made and blended to lubricate a fast moving chain in high friction environment.

I've seen it all used; old engine oil, engine oil/gear oil blend, veggie oil, even washing up liquid and none of them will maintain anything like the correct lifespan that a properly lubricated (and sharpened) chain can achieve.

A poorly lubricated chainsaw chain will wear excessively, and quickly, and will sooner or later break: maybe you could use the Loctite your stick  limbs back on.

it will be thrown off - its not viscose (spelling) enough.


not only will it beggar your chain as Gareth says- it will over heat the bar and stuff the bearings at the end in the process if you are using it for long periods.

My OH says only use the proper stuff, as the cheap option will wreck it. also goes for using correct stuff for hedgetrimmers etc.

What you need is a thixotropic liquid, one that thickens the more you move it. Stihl bar oil will rise up a turning whisk as it clings to the moving parts.

So its thin to go through the pump but thick on the chain / bar.

I have heard that veg oils leak out during storage as they are so thin they pass through the pump unaided.

I know some Thixotropic people

I agree. I bought a chain saw a year ago, and my local agricultural engineers recommended a special chain oil that is very thick and sticky; so sticky in fact that it makes a paste with the sawdust and I have to take off the chain and bar and give it a good clean with paraffin every so often.

Still, that's better than having it break down or wear out quickly.

We used to fell trees and cut them up, now just get logs in and cut up 40ton this year and go through lots of chain oil, 20litre containers. My son is a mechanic and now works at chainsaw and hire place he said "keep up using other oils as thats what keeps them in work" for reasons already given. Our bars and chains last a very long time. To do a test get a piece of steel dip in oil see how it runs off then stick it chain oil see how it is much slower to run off

As someone who makes a living from my saws, I wouldn't dream of putting anything less than Bar Oil in them. I use 2 types. Thick for summer and a thinner one for winter. There are however, times when i have to use Bio oil.(Veg oil especialy blended for chains and makes you hungry as all you smell is Doughnuts!)Usually on conservation sites,water courses and SSSI. But the cost goes up due to the poor peformance of the Oil and undue wear on bar and chain.

I notice that whilst everyone gives strong advice we don't have any first hand experience of the effects of using veg oil long term by some one who knows what they are doing (I am interested in Gareth's comments but then we don't know what caused that damage, blocked oilways? amateur saws are notoriously poorly maintained)

I switched to using only bio oil about 15 years ago because I didn't like the idea of spraying that much non biodegradable oil around the woods. Soon after I tried sunflower oil which before everyone started putting it their diesel cars was a little cheaper than bottled water. So more than 10 years on using profesional saws hard for extended periods, I have gone through 3 stihl 020ts 2 Husqvarna 362s and a Husqy 3120.

I have never had a chain show any sign of excessive wear before the teeth were worn down, I have not had bars show any more wear than with any other oil. The place the wear would appear would be at the bottom of the drive link where it runs on the bar it is easy to see.

The only downside as far as I am concerned is the oil does tend to go gummy if you spill it around the filler cap so your saw ends up looking a bit gross if you don't clean it often.

Of course I am not advising anyone else to use sunflower oil in their own chainsaws just letting you know that I do in mine and am perfectly happy with the way it works.

Robin wood  thanks never thought about using sunflower oil must check out prices as for spraying oil around I see your point but I just feel using two stroke is as bad. Chain bar oil makes dust stick too ha ha so saw becomes a sawdust pile. We found same thing as you we used to pick up used cooking oil and run our tractors on it now people buy it and it just isn't worth doing.

I do the environmentally friendly things that I can that are easy and seem to make a bit of a difference. 2 stroke oil may be bad but it is mixed 1:50 into my petrol and the saw won't run without it, not an easy one to change. For chain oil there is a choice, an easy cheaper alternative that is biodegradable. It works well for me. As someone who is into conservation to be going round spraying gallons of oil around the place just seems wrong.
sod

Robin I agree with you   but Ive never seen it here used for chain oil, one of the reasons we got into used vege oil was it was being dumped and it was a second use of it
Diz

Hmm, sunflower oil.
The first time i used bio oil was on a contract which stipulated the use of it. It was Husky branded. It was put in a brand new 357. After 80 hours the bar had blued and worn badly on the nose. This was put down (by me) as a poor bar. By the Manufacturer as user abuse after some poker face expresions when informed of using there own brand bio oil. The bar and sprocket were replaced at own cost. Another isue arose with it,(not connected to the bar or oil)with  over reving. This was also put down as user abuse. The poor dealer was not having a good month having to play piggy in the middle. So first (and lasting) impresions with bio oil were not good.
Your expirience with sunflower oil seems to have paid off Robin wood. Might be worth investigating further the next time bio is needed.
