Remotely Mazda: Used Oil as Wood Stain

[SparkYellow]

I have a few outdoor benches that I assembled two years ago and stained with used oil from one of my cars. After being exposed to the elements, the wood looks dry and thirsty. Yesterday they all got a coat of Royal Purple 0w20 with 6K miles from the CX-3. I wonder if the purple dye in the oil will leave a darker color.

Waiting for them to dry so I am sitting on a cinder block right now.

I've painted with oil that went through a vehicle, then a farm all. Very dark. Good on an out building.
I've seen driveways sprayed too, a long time ago.

Very interesting. Would there be any issues sitting on that once it dries?

I like the color it adds to the wood. A friend once mixed diesel with oil from his truck and the color is dark-greyish.

Have you noticed that used oil gets thicker after sitting in a jug? The 0w20 was very thin when drained and filled the round drain pan to 4+ quarts. After sitting in a closed container for a few weeks, it is thick like 20w50 and... I felt it was down to less than 3 quarts.

Eventually it will become dry to the touch, but when you rub on the surface, your fingers will catch dark/dust particles. Ok to sit when wearing dark colored, rugged pants. My wardrobe is now mostly black/brown because of how dirty I get on weekends.

It was therapeutic to run the paint roller back and forth. I also stain the exterior of wood wine boxes with this.

Here's a new 2*4 on the left that has been left exposed for one year. The two pieces on the right have been kept inside. Both got one coat.

This piece of tree trunk has been out there for maybe decades. You can tell that the bottom is white-greyish.
