i simply buy the cheapest oil i can get my hands on at walmart or autozone or where ever, then i put that in after draining the old oil out. Then i drive the car normal for 5 mins then drive it hard for another 10 mins. Bring it back home.....drain it out while it's still hot and put regular oil i use/new filter in. I do this every 15k miles and when i go a good bit over my oil life. Everytime i do it...i can feel the difference...engine running smother.
