Good for motorcycle chain
Great stuff. Use it on my motorbike chain and it goes a long way. Chain/sprockets are wearing well with this oil and no rusting. Used about a third in a year or 6000 miles. Goes on regularly. The inbuilt nozzle helps with application.

Jimny diff oil
Used for Suzuki Jimny. Excellent cast too quality as always. Good to get oil syringe in. 5l for £25 is excellent quality (bought in May 2025). Package arrived in time. It has made a noticeable difference in the noise coming from the diff and I’ve noticed a slight increase in performance and mpg. It’s negligible as to whether it’s just be or not but it’s quieter and the Jimny rolls better for sure.
