Recently brought my Rogue lease back for this 2017 Qashqai (you Americans call it the "Rogue Sport"). Unlike the Rogue which gave you the option of running 0W20 or conventional 5W30 (which was awesome because Walmart always has jugs of name brand conventional for $12CDN), the Qashqai's manual does not mention this. I do the bare minimum maintenance on leased vehicles and I'm a little bummed at having to cough up the extra dough for synthetic. Are there any relatively inexpensive 0W20 oils available that will meet warranty requirements? Has anyone produced or is it possible to produce a conventional or semi-synth 0W20?
