Thank you so much for the clarification. It makes sense now! And yes I will make sure to check it at least once a month.The oil light is a low oil pressure light. It’s not a low oil level light. It only comes on when you have low oil pressure and you don’t want that.
Once this is sorted and you (hopefully) have a new engine, it would be a good idea to start checking your oil with the dip stick at least once a month. Check it on a warm engine that has been turned off for about 5 mins to allow oil to drain back into the oil pan. I check mine after I pump fuel.
