-Hi. - A newly made neighbor in the garage turned to me.
- Please give me some oil. I bought a garage. The hinges are rusted and there is nothing to lubricate.- A young man of about 25 spoke.
- Yes, of course, standing in the corner, take it. I pointed to a bottle of sunflower oil with my hand.
This oil has been in my garage for a long time. He used it for cooking bait, fishing. Prepared for discard. And then the young man drew in, just to his advantage.
ABOUTn not suspecting anything took a bottle of old vegetable oil and went to his garage door. Lubricate the hinges.
But at this moment I could not resist and went to him and began to explain:
-Do not lubricate door hinges with sunflower oil. As well as any mechanism with friction units. - I explained to the young man.
- Why did you give me this oil? - A neighbor turned to me with surprise.
- I made fun of you, but it will be a science for the future. Let's go give me some engine oil, you can pour it as much as you like. There was bewilderment, anger and a sense of gratitude in his eyes.
In the process of communication, I explained to him why sunflower and other oils cannot be used:
Outdoors with oxygen, organic oils such as sunflower, olive, flaxseed, etc. They oxidize, from a liquid flowing state they turn into a thick "porridge" or even dry out. In this case, the lubricating property disappears. Conversely, this substance becomes sticky.
Inside the hinge or locking locks, the liquid oil turns into a weak adhesive, causing the mechanisms to jam.
That's how I met a new neighbor and got him to mind.
