Vegetable oils plus STP/Lucas oil for bars

[Billhook]

Anybody bother to make up their own bar oil and would veg oil plus STP/Lucas be much cheaper?

We've been using straight rapeseed oil for years without a hitch.

I never known what is best from lidl  sunflower or rapeseed used both as think price is same,,,,

 

I did look up viscousities at different temperatures....

 

 

 

 

Dunno if it is important.....

Isn't rapeseed oil the only veg oil that doesn't cake when left for a while, hence its use?  I've used it for years without issue but haven't tried any other veg oil.

Just remmebered  its probably something to do with about semi drying and drying oils etc

Rapeseed/Canola has antioxidents naturally. So it's less likely to oxidize compared to some other bio oils, and a healthy choice for cooking with ;). Many bio oils have tachifiers added. In the UK and here in Ireland, it really doesn't get hot enough to need them unless you are averse to sharpening your chains.

I say I work on an estate, but it's really more like a cattle and fishing ranch. I try not to pollute the environs with mineral oil if I can help it. It also saves a huge amount of costs.

Going to try rapeseed oil as others seem to use it without problems, don’t cut as much as some so don’t buy oil in big volumes. Will report back my opinions in a couple of weeks ?

I've tried sunflower and veg oil neat and mixed 50/50 with bio oil and normal stuff.
It's all fine up to about 16-20" bars. After that I get hot bars. Useless for milling with as it gets really hot and smokes.
Not tried rapeseed oil.

Just make sure the oil doesn't dry or get sticky when dry. A small issue for the owner but a bloody great big one when it comes to maintenance and cleaning the stuff off.

Early bio oils were a mare.

Using rapeseed oil do you need to increase the flow rate at all ??
