I dunno, but don't synthetic lubes gum up?
I've always had my chain lube turn to crap eventually after 10 hour inverals

The way I figure it is, I'll have to replace my chain at somepoint anyways
And veggie/non won't make a diff much in the meantime in terms of performance or wear, to me

I'd been using some graphite 'dry lube- that seemed pretty similar to the veggie in terms of performance
Seems like the bio is just as good (and a whole lot less messy/volitile so I can work indoors with it!)

On avg I probably relube my chain every 10 hours, but I also hose it down after just about every ride, too
There much be a myriad of diff. bio lubes to concoct & try!

The other half is that Im just tired of being ripped off my small quantitites and proprietary BS, that, to me,
really don't make a difference to justify me spending money on, compared to buying lube at the grocery store!
Biking is too expensive for me to be buying little drip bottles of chain lube, whether it's bio or not!
I think the grocery store might be expensive since it's regulated for consumption, though
Will have to check out other [bulk] bio lubes
