Another strange thing you never knew you needed before getting into 3d printing.
for Seasoning your e3d hot end I assume?
@Christopher_Benjamin for mature complexions of course 
For mature complexions…and printing avacados?
Inner skincare or seasoning if you like my e3d
Ah, interesting… didn’t know you seasoned hot ends like you do steel cookware… good to know!
But then, shouldn’t it be peanut or coconut oil to prevent the oil from going rancid and to resist higher temperatures without smoking? 
Canola works for a high smoke temp oil at abs and pla temp. Avocado is better at nylon temps. I am going to get some of this soon. Thanks for the post.
Refined Avacado oil have a smoke point of 271 C http://en.wikipedia.org/wiki/Smoke_point
How are you seasoning it?
I took the filament and dipped in oil and ran it back and forth through the heatsink and heat break of the e3d. Then I reloaded with clean filament, brought it up to temp, and extruded 200 millimeters to purge excess oil. Then I was ready to print.
In theory you’d need to heat the oil to its smoke point in order to get it to oxidise and form a patina on the heat break.
Ah, smoke point us 204C.
Unless it’s a new heat break, it would be worth cleaning it out with some nylon first.
@Tim_Rastall I see your point. All I know is canola oil made 10x improvement on my pla print consistency. I made no other changes and the oil did the trick. Trust me… I have a wall of failed squirrel prints to prove it.
I came across this recently. Seems relevant:

@Eclsnowman oh, no doubt. I did say “in theory”
ohh, nice article @William_Baggott
I use Avacado oil to make Paleo Mayonaisse. haha
