A bit of a daft question on grease for the kingpins...

So far I’ve been using Castrol LM grease, it’s what I had and seemed to be ok for the application.

But I’ve now run out of it so have ordered on line some Silkolene RG2 red lithium grease.

There is still some (maybe a third) of the reservoir on the Wanner grease gun that’s still got LM in it.

The question is- Can I just top up the gun with the Silkolene, and of course have a mix of grease types in the kingpins, or do I need to use up all the LM first and then just charge the gun up with the RG2? I’m guessing it will be fine but I read somewhere about “purging the old grease out if you change the grease type” . I’m not sure if this is sound advice, a theoretical ideal that nobody does, or just someone on another forum who actually knows nothing.

Personally I think it would be a theoretical idea but mixing won’t cause any problems in reality..

Thoughts from the learned collective awaited please!

You might be over thinking this. I would opt for any grease rich in molybdenum disulfide.

Mixing grease in a low temperature environment like the King Pins should not be a problem.

If it was going in to wheel bearings I think I would clean out as much as I could but would not bother on the King Pins.

I cant see an issue if they are similar products.

I switched from multipurpose lithium based grease to lithium moly about a year ago with no ill effects.

Both lithium based so they will mix ok.

Not sure whether your Silkolene is Lithium based.

I did remove most of the old grease from the gun but wasn't too fussy with it and certainly didn't clean the old grease out of the stub axles.

I'd be very surprised if you had a problem.

I doubt if mixing greases will cause any issues at all. I've mixed grease with some 90 gear oil in the past and its a better lube if you can get it to stay in the right places.

I'm using red 'n' tacky at the moment.. seems good stuff and they do a green version for hubs. Much better in my view than LM.

Thanks for all the replies.

I’ll just top up the grease gun and crack on, as Griffo says, been over thinking this one smile


And while typing this, postie has arrived with said grease. Only ordered it yesterday through the Bay of E..

Grease is not just grease, in my opinion get some XG 279, Fuchs do it. It is used by the FAA for high wear applications on the Helicopters I've flown for thousands of hours, and the Pongoes use it on their artillery pieces ! Sorry, if you've not been in the military, you won't understand the banter. Cheers.
