use for waste oil - replacement for creosote, etc?

[trevor saxe-coburg-gotha]

My supply of used 10w40 has been building up - I was wondering if it can be used effectively to as a wood preservative? On e.g. fences, etc.?

One possible problem is it's pretty thin - perhaps too thin to paint on. Could it adulterated with something to thicken it? Secondly, is it too hazardous and toxic for t'environment and might it poison a stray kitten's face and gonads?

IMe it produces a long-lasting effect, but can be smelly for longer than normal creosote. I wouldn't use it where anything human can touch it often, but cats don't last as long as people, and I doubt would like touching it anyway. You could try a drop mixed with "creocote" say 50:50 (which is quite thin itself - about half diesael fuel).

Mine gets recycled through my scottoiler.

Excellent stuff for wood fencing and shed preservation but decidedly eco-unfriendly.

If you're putting wooden posts in, soak the lower section in a bucket of old oil. Kills the planet but it's free!

What about making a waste oil burner/shed heater?

I've used it thinned with white spirit on my sheds for many years, to be honest the last one I painted hasn't needed a new coat in 7 years or so, it's still like new compared to the shed my Dad gave me that has some modern crap on it that peels off after a year.

Get rid and recycle it, nasty stuff.

I don't understand why you would want to thicken it up. If you want to use it as a wood preservative you need it to soak into the wood. Mix it 50:50 with creocote and it works well. I've done fences and sheds with it. Mind yourself with the shed though, as it'll take weeks to "dry" off and you could end up getting a bit oily if you're lent up against it admiring your garden / spying on the neighbours.

It will not dry as creosote does. Creosote has an evaporate content so not everything you apply stays there. Most of it should soak into the wood. (Not as penetrative as most think. Real wood preservation requires a vacuum/pressure/heat process.)
So even creosote treated (diy) wood can eventually succumb to rot.

You, as a dedicated horticulturalist, would be advised to err on the side of caution.
Old oil will not penetrate very deep due to its viscosity and will probably just wash off by the rain over time.
Soak into the soil and hamper the growth of your precious brassica and prize leeks. 🤣

Creosote has a high content of phenols and creasols that act as a preservative, i'm not sure modern engine oils are much use here. Neither do you have solid components (i.e. bitumenous tar) dissolved in a light solvent that will carry the slute into the wood and then evaporate.
Neither do you have a polymerising catalyst to get a result like linseed oils and similar produce, forming a plasticised layer both on it own as a surface finish and in conjuction with the penetrated wood forming a composite akin to fibreglass.

"Recycling" turns it into marine fuel oil, i'm not sure it's a good idea to use as domestic heavy fuel oil though.

I use old oil for chain lube. depending on miles, once or twice a week. I can't go through as much of it as I get through with oil changes though.

I don't use a Scottoiler, they're annoying. I pulled the one off the VFR that was on it when I bought it.
