Would You Mind VS Do You Mind?

ould you mind" refers to a more hypothetical possibility, and may also be considered more formal than "do you mind" (I'm unsure about this, though). But I don't really think there is much difference...

Normally, when you use "do you mind", you are referring to something you have planned that will happen, or something that will probably happen. However, in that case, maybe you should use "will you mind".

"Will you mind if I sit here?" could mean "I was thinking about sitting here. Is that OK for you?".
"Will you mind if I call you late?" could mean "I was thinking about calling you late. Is that OK for you?".

In contrast...

"Would you mind if I sat here?" could mean "Suppose I decided to sit here. I don't know if it'll happen, but suppose it did. Would that be OK for you?".
"Would you mind if I called you late?" could mean "Suppose I decided to call you late. I don't know if it'll happen, but suppose it did. Would that be OK for you?".

But pay attention! If you use "do you mind" or "will you mind", you must use the verb in the other clause in the Present Simple. If you use "would you mind", you must use it in the Past Simple.

I use "would." But I have heard, "do." To me, "would" is more polite.
By the way, there is one repeated and consistent error in your post. Can you find it?

Yes you mean "I" you're right I should have used "I"
So is it possible to use "would you mind if I..." instead of "do you mind if..." always?

ffarshaddis it possible to use "would you mind if I..." instead of "do you mind if..."

Yes. It's preferable!

Really? Oh... I doesn't sound bad to me, so I thought it was acceptable. I just thought "Will you mind if I sit there?" would sound better than "Do you mind if I sit there?". But maybe I'm wrong...

In that case, I think using "would you mind" is really the best option.

Yes. It is polite. Here is another common phrase with "mind"

May: We are going now.
Joan: Where are you going?
May: We're going to the new shopping mall. They have a lot of opening day specials.
Joan: Mind if I tag along?
May: Oh no, please join us. The more, the merrier!
