question

Me and me Dad have this discussion quite a bit. Can motor oil sitting in an engine when it's not needing a change harm the engine? Most oil changes recommend xxxxxx miles or every 6 month etc. But why do you need to change it say in the 6 months if you only have 1,000 miles on it? Does it...

So I have a question. Is it better to buy a 4k computer monitor, or buy a 4k tv and use it for your computer monitor? Can you still do that these days? Would it be better to use a computer monitor for your monitor or can you use a tv as a monitor is I guess what I am trying to ask?
