This comment has nothing to do with the oil inside, but about the bottle itself.
I really like those bottles. I keep a few wide mouth oil bottles around that I reuse to hold left overs.
There are two things about this Eneos bottle design that I like.
1) the cap: The threads on mine are designed so that when you tighten it, it gets stiff when it's almost closed and then snaps almost as if it's locking in place.
It seems more secure than the other bottle designs. You also know when it's really closed.
2) It holds up. The bottles from Mobil all start to look like they are under vacuum . They all look like they are sucked in a bit. The Eneos bottle I have is at least 7 years old and still looks brand new.
At this point I'm sure a lot of people are thinking "Dude, it's just a plastic oil bottle!"
But, it's a well designed one. I don't know if the current crop of bottles are like mine but I find them very nice.
