油が残り少ないから買ってきてくれる？って英語でなんて言うの？

There are multiple ways of asking this question. Express the fact that the oil is running low/nearly finished. Then, ask nicely if your friend is willing to go and buy some more. Tips - say 'please' as it is polite when asking a favour of somebody.

It always depends on the context at the time, so where you are when you make this request may have a bearing on what you say. If your friend is going to the shops anyway, you could just say: 'Don't forget I need some cooking oil if you have time.'

"Can you please get some cooking oil we are about to run out?" This explains that the cooking oil almost finished so asks them to buy anything else. "We are running out of cooking oil so can you please get one." This asks her to please get some more as it is going to finish soon.

If you don't have much of something left and don't think you will have enough then you can say 'don't have much left' or 'running low' by adding 'could you buy' you are asking someone to go and get some more for you by adding please you are asking in a polite way

You can simply ask, can you fetch me some oil? This is a simple way to request that someone purchase the item for you and bring it back. You could also make a statement followed by a question. For example, I don't have any cooking oil left, would you mind buying some for me? Asking someone - "do you mind, or would you mind" - is a polite way of requesting someone to do something for you.

1. When you we ask a question with "Would you mind...?" this is very considerate and polite. 2. To run out of something is the same as the supply being low. 3. As going to the shop is an errand to be run, we could ask the person for a favor. A favor is when someone does something nice for you. It is a good idea to state that the supply is low, or why you are asking the favor of running this errand.

When ingredients 'run out' they have almost depleted and need to be replenished. We replenish ingredients by buying more at the grocery store. We can either go to the store ourselves or ask someone to go for us.

"Can you grab me some cooking oil?" to 'grab' something is to pick something up or hold something, in this context it is a very casual expression, ex. "to grab something from the shops" "Do you mind picking me up some cooking oil?" 'Do you mind' is a very polite and casual expression used when asking 'can you'.
