Amsoil 'Dominator' Synth Grease Oil Separation

[infinityshock]

I have two tubes of amsoil 'dominator' synthetic racing grease in two different grease guns. both guns are leaking severely to the point of leaving a large stain on the wood and concrete surfaces they are stored on. one of the tools i use the grease in is a jackhammer and the joints in the grease housing cover are 'leaking' a fluid. there has never been any sort of leakage with other grease types ive used.

I sent an email to amsoil asking about this issue and their reply was that separating oil is within design specs. Looking at the spec sheet, it calls for about 2% separation per 24 hour period, meaning in less than two months all the liquid oil will have leaked out

I started using the amsoil grease after reading good reviews of it on the internet however i havent heard any mention of this before. even if this stuff is the best grease out there it is impractical to use if its going to make the grease gun so slippery to be unusable

does anyone know how this oil separation will affect the actual performance of the grease and if this sort of thing is normal?


My experience with grease:

- grease gun filled with some unknown grease i purchased at sears in 1994: never leaked, and the grease is still 'greasy.' the small grease gun is sitting in a tool box so any leakage would be visible
- 'coastal' grease in small cardboard tub purchased in about 2003 where the cardboard appears to have absorbed some oil. the tub is sitting on a metal shelf where any leakage would be obvious
- ive used multiple tubes of assorted types of 'lucas' grease in small and large tubes and never had any leakage of any sort from either of the guns or machinery it was used in
- 'hitachi' grease which is very thin, has never shown any degree of separation or liquid leakage

I have had this happen on their Series 2000 grease, which I believe is the predecessor to the Dominator grease. Very frustrating making a mess dripping out of the grease gun while trying to be neat about stuff.

This happens to me with all grease. Ive stopped greasing stuff for the most part because of it. I just pack a little into a device, use it seldomly, and then keep everything apart and empty.

Did you ask tech services if there was a better choice, like their heavy equipment grease?

Racing grease isn't made to last long, it's made to have the least amount of friction possible.

I experience this when I grease the steering head bearing on my Harley Davidson Street Glide motorcycle on hot summer days. Oil from the grease runs down the forks.

2%-6% separation is typical of lithium based greases and many other thickeners - you can try mixing it back together, but it usually doesn't work well. Generally this doesn't affect the grease performance as long as you maintain an appropriate greasing interval. As far as it running out of your grease gun, again this is typical, if you leave the grease in too long, you are right about being concerned that as the oil separates - it could lead to excessive grease hardening. This usually takes years, and hopefully whatever you are greasing is getting new grease more regularly than that.

If you are really picky about oil separation, there are other types of thickening agents which are much better and can have less than 0.5% separation (aluminum and some calcium sulphonate thickeners) These greases typically cost 2-3x more than a cheap lithium grease though.

Yes, their (Amsoil's) Off Road, Polymeric HD grease has NEVER separated/run on me yet, either from the gun, or out of the suspension components I use it in.

The reason I went to this viscous grease, from either Red Line, or Amsoil's series 2000, is BECAUSE of the way they ALWAYS separated and ran, and also to quiet down noisey Roto Joint suspension ends which always 'pounded out' ANY other grease in no time.
