A calcium complex grease should shouldn't give you any problems in a chassis lube application, just try and push most of the old lube out when you make the switch.
Okay...my research is complete...Here is what I can say about both MYSTIK JT-6 greases:
It is true that the standard "vasoline-looking" JT-6 Calcium grease is good against water; in fact it is less than 1% water wash-out!!! That is better than
ANY MARINE grease I compared it to, even though it is not claimed to be a marine grease. But, I was looking for a "one-size-fits-all" grease, and based on that, I had 3 issues with this Mystik standard Calcium non-hi-temp grease.
1.) Based on a compatibility chart I saw, it is not compatible with one of the current greases I have in service.
2.) It is not as good for cold temps and in winter here it can get as low as 0* on rare occasion but mid-teens are normal and the grease would be like clay in those temps LOL
3.) It is not a hi-temp grease so when I needed to pack disc brake wheel bearings, it would not cut it.
As for the answer to my quest...I have selected the Hi-temp Red Mystik JT-6 no2 grease as my default grease for all applications. My reasons & findings are below:
1.) I looked up the specs on comparable greases as well as various Marine greases and in almost every case, This Mystik Hi-temp multi-purpose was superior. Again, there was at least 1-2 calcium or aluminum marine greases maybe with
slightly better water wash-out resistance, but I HAD to use a Lithium-based grease for compatibility & wanted the better temp range also. Some of the brands of greases I looked at were Valvoline, Sta-lube/CRC, Mobil-1, Supertech, and Exxon...I did look at a few Castrol options, but did not take the time to compare them because Castrol Grease in the 14oz tube is hard to find here except the blue non-lithium kind. Also, I considered Lucas, but I wanted matching grease in tub & tube and Mytik was easier to find both ways so I did not consider any grease that I was not going to be able to go & buy.
2.) The main stuff I compared was operating temp ranges, Timken Load tests, drop point *F, vicosity & water-washout resistance. There might have been more, but those seem like the main ones. Suprisingly, this Mystik grease outperformed everyone; even against some greases that were more application-specific. For example, at one point, I was thinking I would use Supertech Marne grease for everything because it seemed to have a decent op-temp as compared to other Marine greases, but the Mystik JT-6 Hi-temp beats that ST Marine grease in water-washout!!! The ST is made by Exxon BTW, and I had to use Exxon branded grease specsfor the ST because Wal-mart did not have them posted & the MSDS was incorrectly linked to Min-wax stain LOL. But I figure the ST is close to or the same as the standard EM Marine grease specs & the Mystik shows to be better if their tests are true. Heck the Mystik was better than the Mobil-1 synthetic grease in many categories!
3.) I DID NOT compare to any moly greases because I wanted to make the switch from one of the current greases I have in service that is moly and I do not want moly for my one-size-fits-all grease.
I am sure there is more I am leaving out, but the point is, for those of you who also want something to use in boat-trailer bearings, chassis points, disk brake wheel bearings, and regular trailer bearings, the Mystik JT-6 Hi-temp grease appears to be the best choice among the greases I investigated. I went soley off the data sheets and some posts I read, but on paper it is the winner. Again, I would like to run the lower-temp vasoline-lookng Mystik for my chassis & marine apps, but I do not want to have 2 seperate grease guns nor do I want to have to clean out all the old non-compatible grease; I wanted a grease to use that would mix right away with no hassel. And the fact that it will still resist water washout to 2.5%, that beats most ofthe others I looked at(including Marine grease), so it should be good enough for marine apps & deep water crossings in the Jeep. Only Ford seems to require moly in their chassis so I am happy to be able to switch since I do not have any Fords
I hope this mess of a post helps anyone who also was looking for a one-size-fits-all grease...again, I kinda wish it was the ST (supertech) Marine grease, but data shows the Mystik to be better and it is only a few cents more per tube and can also be bought at wally world. As for the 1lb tubs, I got those from Tractor supply so I am set.
I am sure there are better greases out there for specific apps, but I did not have time to look at them all and I have always trusted the Mystik name, even though they are not made in my state anymore
My main challenge was finding something that was compatible with ALL of my current various greases in service, and something that could be used for boat trailer bearings & resist wash-out, as well as hi-temp bearing apps & chassis.
