Synthetic grease ?

Any good/bad experiences with using synthetic grease on driveline/steering/clutch lube for a (mostly OEM) '86 CJ? Valvoline non synthetic is listed as -10F - 400F for working range. It gets colder than -10 in WY and I'm thinking of switching to synthetic which is listed as -60F. The Valvoline synthetic is lithium complex with 1.5% moly. This apparently meets Jeep and GM specs for lithium-based lube, but does not meet Ford specs for moly-based lube. Thanks for your input. -Joe

Re: Synthetic grease ?

I use synthetic for everything in my 74, except engine oil

Re: Synthetic grease ?

I use Valvoline synthetic in mine and it works good but then again, it only gets down to the 50s here. Where do you live in Wyoming? I grew up in Greybull. Definately colder than -10 in the winter.

Re: Synthetic grease ?

Hi Mobdawg,
Laramie. A few times it's gone down to -40s. As you remember, the axles and driveshafts get very "stiff" and it's difficult when it's that cold to get a vehicle moving. 50's? It was colder than that this am!

Re: Synthetic grease ?

I bought some Mobil 1 synthetic grease for suspension/steering. It works fine, but it seems to "seperate" after it sits in warm weather. Oil drip out of the grease gun and runs all over the place the second time I use it. It makes a messy job messier. I also notice some oil dripping out of the grease boots on the tie rod ends. Doesn't get that cold around here, so I can't comment on cold weather performance.

Re: Synthetic grease ?

I've noticed the phenomenon the separation of the synthetic grease as well. I was buying Canadian Tire's synthetic grease, and I notice when I open up the ends of the cartridge, oil runs out. Their grease is red in color, manufacturor, unknown. Not sure if this is an actual problem.

Re: Synthetic grease ?

I have noticed that with non-synthetics too, especially after the grease gun has been stored in a hot garage. It has happened with Valvoline and Lubriplate greases.
