I'm pretty sure the 'European Formula' label is just a marketing thing, it's still Mobil 1 0W-40. It's worth mentioning that Mobil 1 is not what it used to be. You can read a ton about oil on this forum, but I switched to Castrol 10W-40 so you may want to look at that. I also switched to a spin on oil filter but I was previously using the Wix/NAPA Gold 7211 Oil Filter, which seems less prone to disintegrating on the ends than other paper filters.
