TheSamba.com :: View topic - Trouble Finding Moly CV Grease

Thu Jul 10, 2008 5:08 pm

I'm having trouble finding Molybdenum grease specifically made for CV Joints at my local autoparts stores. I'm in the suburbs of Chicago, so there are lots of stores around. Maybe everyone just buys reconditioned axles these days, and no one needs to buy grease? I hunted four major franchize stores and the only thing I came up with that claims to be for CV Joints is this synthetic grease from Valvoline which says it is "moly-fortified". Here are the product claims from the web-site.

SynPower Synthetic Grease is an excellent heavy-duty and multi-purpose automotive and industrial extreme-pressure grease. SynPower is formulated with a lithium complex thickened in a synthetic base oil, moly and other premium additives to provide superior protection from high loads and extreme temperatures.

Provides superior high- and low-temperature protection (-60°F to 425°F) over conventional greases
Exceptional resistance to heavy loads
Moly-fortified for increased film strength
Extreme pressure fortified
Inhibits rust and oxidation
NLGI #2 GC-LB lithium complex EP grease

What do you think?

It's not the same thing. If you can wait a day of two you might be better off ordering it http://aircooled.net/new-bin/viewproductdetail.php?keyword2=SSJ0015&cartid=0705200875809088

What do you think of this one? It says it includes molybdenum disulfide and it is black. BTW thanks for the warning about using gloves. Unfortunately I have gotten it on bare hands in the past. Anyone started a study on auto mechanics and cancer incidence?

I would sure think that living in the burbs in the Chicago area you should have a NAPA or any parts house that would carry CV grease.

The link between the chemicals mechanics come in contact with and cancer has been established...

That Valvoline one states that it is for use on CV Joints so it should work. I have never seen or used that grease though. Does the second one specify CVs? It looks like what you need but I would be hesitant if it didn't say CV Joints on it. Usually a good boot kit comes with the grease... Moly grease might be something they have behind the counter... Autozone lists this grease as being stocked at stores.

I would worry about the Moly-Graph grease, it might get its black color from graphite and not actually have much moly. I don't know that you need a grease that specifically says for use with CV joints. I have never looked for that on the tube, just the moly content or color. I usually just use Valvoline moly as that is what I can buy locally and I feel I can trust Valvoline to continue to put out a good product. I have never had a CV joint loss in thirty plus years no matter what brand moly I have used. The only problem I have ever had was with the OEM grease on my 91 Multivan, it caused damage to the joints in only 20k miles or so.

Do the sniff test. Smell grease that you know is correct, with molybdenum disulfide in it, and you will never forget the smell. Test the others and compare! The tube I have says NLGI- 2 on it and contains molybdenum disulfide on the ingredient label. Made by Citgo, named Mystik.

Way back in the late-1970s & early 1980s, I couldn't obtain molybdenum disulphide fortified grease, at any of my local car acesory shops or motor factors.

I finally discovered a second-hand carton of Valvoline molybdenum disulphide fortified grease, in a charity shop, in the suburbs of San Diego, California, during my holiday in September 1981.

Thanks for the links.

The Sta-Lube product does NOT list CV-joints in the intended uses category. The Valvoline SynPower does. Of the four different Valoline products that were on the shelf, only the "moly-fortified" SynPower specifically lists CV-joints as an intended use. It was of course the most expensive at $6.88 for 16 oz. Which still costs less than buying it by the small packet.

I called the Valvoline support phone line this morning and the tech assured me that this would be the correct product and that it does contain molybdenum disulfide, although he could not tell me the percentage of composition. He also verified the temperature range listed on the web site -minus 60 to 425 degrees Fahrenheit as being correct (the narrower range listed on the product label is reportedly incorrect).

The Valvoline synthetic grease will provide longer wear protection than standard moly based grease. Use of the full synthetic will likely be the last time you'll need to mess with the CV joints, so long as your boots hold up.
