Oh my, that does look different. There has been a lot of discussion here about singer lube. I've read about not being able to buy it in the US anymore, there seems to be a blue tube that is still available in Canada, and Joe says the white lube is only for plastic machines.
I have 2 tubes of vintage lube..... green tube. Both tubes look exactly alike on the outside. But, one tube has a yellowish oily lube and the other one is more white. .... so I don't know what the answer is. And, I'll be watching once again to see what the experts say.
