Cheap supermarket oil for a few miles, repeat, fill with correct oil.

Would running engine on idle for 5 mins be enough, or do I need to drive it. Also am I correct to think you don't think I should add any type of flushing agent as well?

Pretty much any multigrade will do. Best to change the filter when you put your good oil in.

Because engine very contaminated with sludge I'm going to use cheap oil and flushing agent.. And yes will also change filter with final oil
