At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Green Oil's Wet Chain Lube is an exceptionally good barrier against water, dirt and corrosion, seriously reduces maintenance and won't turn the planet into an unliveable wasteland. The price is good, and the applicator is well designed. There's really nothing not to like.

The most striking thing about Green Oil is the bold claim that one application lasts 125 miles, or even more. To be quite frank, I didn't believe it. Rural roads can be hell on drivetrains even during the summer, and none of the wet, dry, ceramic or wax lubes I've tried have ever come close to a mileage like that. Especially not in winter, where rides regularly end with a bike looking like it's been stolen from a cyclo-cross.

To test the claim, I cleaned the chain and applied lube as instructed – one spin round from quicklink to quicklink and it was done. A quick buzz through a rag took the excess off. I didn't add a drop more for 130 miles.

After almost every ride I wiped the chain by spinning it through a rag to remove blackened goop from the sideplates. Though I felt that was necessary, Green Oil is noticeably less sticky and grime-loving than many wet lubes, and the build-up was nowhere near as bad as some.


It has a slightly matt sheen and (after a while) an almost snotty, semi-dry consistency that really is tenacious, yet it's remarkably resistant to contaminating so badly you have to strip it all off and reapply it. A welcome knock-on effect is that you get through a lot less degreaser as well.

Even after 100 miles, I could leave the bike a couple of days, come back and spin the cranks backwards without problems. With many lubes you'd find the chain skipping and clacking as stiffened-up links struggled to bend, and you might well find rust spots too. No corrosion here.

All this makes Green Oil's Wet Lube particularly good for commuter bikes, gravel bikes, or road bikes on multi-hour rides through the worst conditions.

Low on syllables

This impressive tenacity is said to be thanks to N-Toc, which sounds like a rapper but is in fact a refined plant extract with similar long-chain molecules to petrochemicals. Obviously, there are no petrochemicals, such as polytetrafluoroethylene (PTFE) – the stuff that makes Teflon, GT-85 and many chain lubes so slippery – in Green Oil at all.

The entire product is super eco-friendly. It's totally biodegradable, packaged in recycled plastic, and your bottle can be refilled at a small (10-20p) discount by selected bike shop dealers. Even the ingredients are sustainably sourced, so Green Oil isn't simply passing the ecological impact up the supply chain.

To be clear, this test was harsh at times, especially towards the end as we moved into storm season. The Wet Lube has seen some very heavy rain, near flooded roads and also plenty of salt after some frosty mornings. The back lanes are also covered in mud that has been dragged out from the fields.

Green Oil recommends really slathering the chain if there's snow about (to protect against the road salt), but I didn't like the blackened result of the excess, or the fine grit it presumably held. Keeping it thin by wiping (especially the side plates) did not cause any issues.


This 100ml bottle costs £7.99, which is similar to the likes of Fenwicks Wet Weather Chain Lube (£8) which Jim found very impressive when testing it for our sister site

You can spend a lot more though. Wolf Tooth's WT-1 All Conditions Chain Lube is £19 for just 59ml, although they reckon you can go 400 miles before reapplying it, and Neil agreed.

The Green Oil's cap isn't secure enough for for travelling or bike packing duties. For that, Green Oil sells the 'On Tour' bottle, which is a virtually leakproof 30ml container of Wet Lube that can, obviously, be refilled from this 100ml one.


The Green Oil Wet Lube offers impressive performance, and not just from a smooth-running point of view – it's good, too, from an eco angle. It's also well priced.

Tell us what the product is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

Green Oil says:

- Penetrates

- Lubricates

- Protects

- Prevents rust

- Lasts over 125 miles per application

"Green Oil chain lube was developed in 2007, and is the country's if not the World's first biodegradable bike chain lube. It lasts in excess of 125 miles on the chain per application and has won a wealth of awards - from environmentalists and the bike industry based purely on performance.

Green Oil Wet Chain Lube has an easy to use and much immitated 'snap cap'. Simply twist and pull off in one go. It has a fantastic long nozzle, easy to get into hard to reach areas.

Green Oil Wet Chain Lube now contains N-Toc, a special refined plant extract to increase durability, increasing the length of time between applications.

Green Oil can also be used for cables, brake leavers, bike locks and for other lube applications. It's versatile.

We don't want to encourage too much flying - climate change being a problem of course, but if you do need to take a plane you an take Green Oil with you. Green Oil is within the 100ml fluid limit, so you can even take it in your hand luggage (for a cheeky bit of on plane bike maintenance perhaps!).

Why use chain oil?

A chain can be over 99% efficient in transfering energy from your pedaling to kinetic energy to drive the bike forward.

Friction occurs between links, and lubricating the chain reduces this - increasing efficiency.

Also, your bike chain is exposed to the elements: water + steel = rust.

Rust = reduced efficiency.

Rust and wear due to friction of course make cycling more difficult, but also reduce the life of your bike chain. Green Oil chain lube reduces both, extending the life of your chain and reducing friction, for a smoother ride."

I think it's a great lube that is easy to apply and copes well with rubbish weather.

Tell us some more about the technical aspects of the product?

From Green Oil:

How is Green Oil green?

Other chain lubes out there contain PTFE and petrochemicals. They don't even bother with proper recycling information! This is crazy, as every fluid used on a bike ends up in the environment, and usually on a mechanic's hands. And your hands, and in your garden. Most street drains lead to rivers too.

- PTFE creates a carcinogen in its production.

- PTFE accumulates in the food chain, after your bike chain. We don't use PTFE

- Petrochemicals often do harm in the environment and aquatic life

We therefore don't use PTFE or petrochemicals, only natural ingredients.

Green Oil Wet Chain Lube is 100% biodegradable.

We don't use palm oil - all our ingredients are sustainably sourced. We use plant based ingredients, natural molecules with similar long chain molecules to those found in petrochemicals. The mixture used is sticky enough to stay on the chain, but not so sticky excess dirt sticks to it.

Every Green Oil bottle is made from 100% recycled plastic - so don't be surprised if the bottle is a curious colour!

We also provide 5 litre cans of Green Oil Wet Chain Lube to selected bike shops and workshops. This aids the re-filling of bottles, and reduces packaging. Each comes with a giant hand pump, making re-filling easy.

The holding box design is based on an old Schweppes bottle deposit box found in a skip outside a pub, which was renovated and we still have in the office today! These holding boxes are made from British reclaimed pallet wood.

It really is good stuff. Used on customer's bikes (and my own) for 18 months and had no issues at all. Customers also love the 'plant-based' angle, which on it's own wouldn't be enough to choose it over the Fenwick's used previously (and currently for certain applications because they're also excellent) but as it's so effective I'm happy with it being our main lube for the workshop, along with their EcoGrease which is also excellent. The business owner (Simon) is also a top bloke and they really do walk-the-green-walk rather than just dusting eveyrthing with eco pixie dust for covenience's sake.

Is there a list of shops that offer refills? I could not find anything on the Green Oil website.

I have never seen any offering it. If you look on the website of their UK distributor i-ride there are very few shops even listed as stockists. I bet it's a bit of an uphill battle with the proliferation of brands in this sector. My LBS already carries several other well-known brands so I wasn't surprised that they were not interested in adding Green Oil to the shelves, despite (or perhaps because of) its USP.

I buy mine direct from Green Oil's own online shop, I've been using it since the first review.

Rust and wear due to friction of course make cycling more difficult, but also reduce the life of your bike chain. Green Oil chain lube reduces both, extending the life of your chain and reducing friction

I appreciate that friction would be difficult to measure, so you can only give a subjective assessment. But chain wear is easy to measure with a ruler. Did you find any evidence for the claims about chain wear? For me that's the biggie, is my drivetrain being quietly ground down and worn out?

Also, the review seems to imply you maybe only tested over 125 miles in total - to check out the manufacturer's 125 mile claim. How far did you test on total?
