...is there such a thing?

And if so what's available other than Green Oil? I currently use a dry lube and Green Oil is a wet lube so is less than ideal, so are there any other biodegradable lubes I can use?

I've heard of a chain lube that when applied to a clean chain, the chain never needs to be cleaned again, just the lube re-applied. Does anyone know what that lube is called?

Hype. A chain must be removed from the bike to be properly cleaned, otherwise you wash the fine crud down into the pins and plates making grinding compound.

there's a huge amount of lubes produced that are "green", but it's harder to find those that are "sustainable."

i personally use my old kitchen fat/wax and it works quite well.

Why worry so much about the lube when your bike has amassed so many non green miles/ non eco friendly grams of carbon ?

Alice in wonderland oil. Much of what makes a decent lubricant, also makes it attract and adhere dirt. Even the cleanest lubricants need at least a dry wipe before re-applying. There's also the effect of wear by product (steel dust) which accumulates within the chain, so there's no magic answer.

As for biodegradable oil there are a few, and they're OK, but in my experience the fact that chains are exposed to weather might make them problematic because of things like rancidity, or low resistance to water wash out. Dry biodegradable lubes are tricky, since most so-called dry lubes are teflon or something comparable and a volatile solvent, and other than water there aren't many green options.

I expect that we'll see more choices, and greener lubes every year, but in the meantime, other than the solvents we put into the air, the environmental impact of the few drops of oils used on bike chains is miniscule.

In fact, it might not make sense to use a "greener" lube if it shortens chain life, since the environmental impact of making a replacement chain and disposing of the old one sooner than necessary could be far more material.

Semen.............................................it's called semen.

It's more to do with the disposal of the chain-cleaning fluid which will contain some lube - I want to avoid dumping potentially toxic chain lube into the sewer which ultimately ends up in the water supply

A bike that smells like Bacon. Have you had any dogs following you home?

they sell the stuff here in finland as chain oil, same as motorcycle chain oil.

Well I run my car on WVO, and I opened the container of bio chain oil and I think the smell is dead on!

it is also excellent for bar chain oil on the chainsaw!

It might be biodegradable when new,it's not after you use it......Unless your going to wash your plants with it.

Biodegradable in what time frame? I don't want my chain lube to start falling apart while it's in my chain!

I had high hopes for 'Squirt' but in my estimation it's the worst 'lube' I've ever, er, come across.
