JCB Blue lithium waterproof grease.
Was the only thing that kept my Landrover wheel bearings alive when I did a lot of off-roading.
For bike stuff I use the cheap and cheerful Comma stuff in the tub in eyerideit’s post.
One tub lasts for ages.
I also have a tub of Comma copper grease for anti sieze applications.
There is a lot of bullsh*t spoken about grease and lubricants.. for 99% of bike applications, cheap and chearful automotive grease works just fine…
However I’m an Engineer, who does a lot of work with mechancial lubrication (on Navy ships and Submarines) – I’m sure the Park Tools salesman knows better.
