It seem like you can only purchase 12x1L packs of Mobil Delvac 75W90 gear oil in Canada. The tranny takes 3 litres so its a bit of an overkill. I called the Porsche dealer and the quoted me $50 a litre for their lube. The delvac stuff is $240 for 12L. Does anyone want to split a purchase with me? Better yet, does anyone have some fore sale around GTA?
