Really, you're heading down the wrong trail. At breakneck speed. I'm an English major, BA and MA, and I taught both English and Logic/Critical Thinking at university level. I'm a published writer, and I've edited 4 magazines. You arguing language with me is like me telling you how to restore a car. I know that I would end up looking foolish in a very short time if I were to do that.
There is no other meaning or interpretation for the word Restore.
All language is open to interpretation, as I'm sure you realize, deep down. Most disagreements are due to different connotations of words, i.e., contextually different definitions.
Therefore it is not an "oxymoron". The word "restore" has no dual meaning for how it is used.
First, yes, "jumbo shrimp" is an oxymoron. It's also a phrase that describes a real thing. That's my point.
Second, the meaning of words changes over time. This is why the Oxford English Dictionary people get together every year and decide what new words and phrases to add. So, "over-restore" may not have appeared in a dictionary yet, but that doesn't mean that it has no meaning, nor does it mean that it doesn't describe a real condition. "Cyberspace" is a made up word, and when it was made up, it described something that already existed, something that people needed a word for. "Selfie" is one of this year's new words; it, too describes something real.
So, language is what it is, it changes, it evolves to meet the needs of the times, and your blood pressure will be a lot lower if you just accept that.
Now, this ultimately started with you making a statement, and me trying to clarify your meaning (connotations, again). Alan had pointed out that you were changing the vehicle when you went through your restoration process, and your response appeared to be "That doesn't matter, because the change is invisible." There's lots of ways to interpret that (interpretations, again) but I want to first verify that that's what you meant to say
