Mixing grease
I’ve got a 31 pickup I’m about to grease everything that has a grease fitting. I like the Lucas “red sticky grease”. Are there any compatibility issues with using that grease with grease that gas been in the car for 90 years?

It's hard to imagine that a car has never been greased in 90 years! If that is really the case, every kingpin, every tie rod end, etc. is either worn out or seized and in need of replacement, in which case just use the grease of your choice. Otherwise, just grease away! The new grease will push most of the old out and what's left won't matter. |

Re: Mixing grease
The old greases (chassis) may have been calcium, sodium or soap based while many of the new ones are lithium or Moly based . BELL PERFORMANCE has a good article about compatibility issues as you state. If a concern, track down some grease that is non- lithium based, such as Valvoline General Purpose grease for chassis not subject to high heat..

Re: Mixing grease
Grease compatibility is very important. I learned this the hard way. Check with Lucas to see what kinds of grease theirs is compatible with and go from there. If you can't verify what grease is in your joints, you may have to flush it out. https://www.machinerylubrication.com...-compatibility

Re: Mixing grease
Many use mystic JT6 long strand for wheel bearings and anything else. Thick stuff that clings. Look it up to check it out. Search here and the internet.

Re: Mixing grease
Wouldn't comparability become more of an issue when something like a wheel bearing is packed with grease which I would hope they would be cleaned anyway? If you get your car lube back in the day or now, they are going to pump if full of what they sell, which may not be what is in it now. Most areas you would be flushing out the old grease and more then likely the u-joint housing is mostly dry anyway.

Re: Mixing grease
Pump enough new grease into the joints to drive out the old grease and stop worrying.

Re: Mixing grease
[QUOTE=The Master Cylinder;1949919]And why is that? Where does the grease go? [/QUOTE
1 because it was never filled or under filled in the first place and 2 because it leaked/forced out. The u-joint housing is not completely sealed and grease can get forced out by spinning u-joint. I have worked on a number of A's that might have had a pump or two in the housing and that was about it. Could get washed out when 600W gets forced thru the rear bearing (not every transmission has newer sealed bearings installed) or bad seal on driveshaft allows it to move down the shaft. I saw the smile faces after I posted this! LOL
