You guys in the USA are blessed to have cheap Mobil 1 oil sold in costco. We only get Castrol syntec at the costco in my area.... one caveat ... comes in this 12qt BagInABox trick
kinda tough to put the used oil back in the bag ... not to mention it's after2 changes
oh well can't say I didn't try to minimize footprint

Bu we are getting Mobil1 0W40 from our canadian tire shops, when on sale, it goes at approx $7 a quart. Not bad, given canadian prices are generally higher than the USA in general.
