The invoice seems to be correct.1WPE-14-302 is the correct oil filter. 9956-41-400 is the correct aluminum drain plug washer. 5 liters of synthetic 0W-20 bulk oil part # 0000-23-0W20-CA by Petro-Canada looks good too.
Good thing it's the correct oil and filter. Thanks for confirming.
I will make it a habit to check the oil frequently.
I will be more informed next time I visit the dealer.
