I've recently brought a used car and there is oil that has already been topped up in September from the service history. I tend drive the car every weekend and will be checking the oil levels soon just wanted to check if its necessary to have the current oil drained out in the event i have to run out and purchase some oil to top up due to low levels?
Thanks in advance
As an aside, my cars moaning at me for an engine oil change and serivce, but its 18 months old and not even done 8k, can I ignore it for now? (I can't find the manual in case you're wondering) I'm not sure if changing the oil is something I can reasonably do myself or i'm best leaving to a service.
