I paid $20 last time, Plus 4 liters synthetic oil and a filter. That ran around $35. I had to order the oil on Amazon because I couldn't find 0W20 locally. Well I found it at AutoZone for twice the price of Amazon. In these parts AutoZone and Home Depot are the most expensive shops going. You go there if you have no other choice.
Good for 10,000 km. About a year for us.
