Green Oil was created, because nothing similar was available. Simon Nash, the company founder was riding his bike through the river Quaggy, near Elmstead Woods in Bromley. He realized his chain was in the water, and lots of rides involve a river crossing at some point. Looking for an alternative to a petrochemical polluting lube, nothing was available.
Most brands available at the time were imported, and didn't even bother to have recycling information on. Many had the 'Dangerous for the Environment' dead fish and tree logo on. 'No one should make lube like this' he thought. Of course, every fluid used on your bike ends up in the environment. PTFE accumulates in the food chain, and petrochemicals pollute rivers and wildlife, so what's in your chain lube is important.
In his last year at University, Green Oil was developed. It utilized only plant based, and sustainably sourced ingredients rather than petrochemicals. Recycling information was clear, and sustainability incorporated from the beginning. The first bottle sold to the public was to a man in Trafalgar Square, London as cyclists gathered to watch the Tour de France, which in 2007 started in London.
