A and B Service

Hello, my wife’s 2022 jazz was driven even less last year than before and now has just under 10tkm on the clock. With annual service I think about whether we want to do without the oil change or not request it in a quotation, if the car does not require it. For the guarantee this should have no effect, if the car does not require it. When would the next oil change be necessary then? Can this then also be in the middle of the year or can one then participate with the next service? I learned lastly that the time of the service itself does not set the counter back to the execution time but to the planned time – so I will not ask the dealer about this question …
