Motor Oil W/Molybdenum

givette
In your travels, has anybody seen "off the shelf" motor oil with moly (molybdenum) additive in it? I'm interested in a walk-in purchase at some store. Sears? K-mart? Wallmart?

Thanks in advance. Joe

    Yes. Spelling may be off. I'm looking for oil w/moly additive [molybdenum disulfide]. Thanks. Joe.

    EDIT: I don't want just the additive. I can get that. Can't seem to find pre-mixed motor oil with it in it, thats all. Joe

    The closest I ever found to it was the old Arco Graphite - now discontinued for maybe 25 years.

    I used to buy Molybdenum Disulfide in a colloidal suspension, in gallon jugs to add to my motor oil in a 4:1 ratio. I think I may still have some buried in the barn.

    When the first synthetics became available (Mobil 1) in widespread distribution, I did some head-to-head comparisons, and found the synthetic to be better than my cobbled up mix.

    What do you want to use it for ??

    Hi, Doug: My goal is to cause a molecular build up of the moly in my engine on all friction surfaces. Decrease tolerances, to use another phrase. I haven't found a non-moly based oil that can reduce engine tolerances. Only aid in lubrication. And yes, I can remember moly oil years ago. My quest continues. Thanks, Joe

    Don't know if it would work in your qpplication, but Honda markets a Moly oil through their motorcycle dealers.

    That was part of the reason I used it. Based on compression tests I did on a small-block Ford - 302 - on a new engine, the moly raised compression about 15 pounds, and extended the lifter pump-up range a little less than 500 RPM. This was after 1,000 miles from adding the moly.

    When I was buying it - mid '70s - it was $85.00 a gallon, wholesale. That was good for four oil changes.

    What is the engine application. Old one or new one ??

    I don't believe you will find any SAE rated oil with moly in it, today, any where in the world. By the way, you might check the SAE website for recent testing and current products using it.

    Did you know that, in addition to its' property of bonding to metal, moly is the slipperiest substance known to man ??

    Thanks guys. To Doug...older toyota w/dohc. No hydraulic lash adjustment. (Tappets). I'm getting to the point that the engine will benefit from tighter tolerances. My valveguides and cam lobes will tighten up by going the moly route. My cam lobes interact directly with the valve stems via shims. Starting to hear the "tickity-tick". No oil by-pass yet. My goal is to "freshen up" the engine this side of a tear-down. Best to all of you who responded. Joe

    EDIT: to Tomh...unfair question, but do you know if the motorcycle oil is high detergent,(street) or ashless dispersant(racing/aviation)?

    The only oil I have seen with it lately is the Honda oil
    like tomh mentioned.

    Don't know about Moly.. but oil with teflon in it worked wonders in my first car.

    Don't quite recall what it was called, but it suddenly ran smoother, started easier and could idle at much lower RPM's.

    Molybdenum is one hard (brittle) metal that oxidizes from other experiences. I never noticed it as an oil additive. If you come across electrodes or bars of it, molybdenum can be very profitable at the recyclers. My guess is molybdenum is an expensive oil additive.

    Check out 'Molyfusion' on shootersolutions.com. It will not build up the walls but it has worked for me to get about a 30% increase in mileage. My wifes Yukon (2005) gets 19 average between city/highway and that's a big improvement.

    The directions look like they were written by a monkey but the product works even past an oil change. I have my own directions instead of the 10 pages of WTH did that say. They are: change oil leaving 1 qt out, pour Molyfusion paste in oil port, Pour in last qt, CLOSE oil port. Drive. That's it.

    To all: thanks for the responses. To Capt. yes, it's expensive. The undiluted additive is approx $2.50 per ounce. Approx. 4 ounces needed for average crankcase volume. It requires 3,000mi to take a "set" in the engine internals. I have come to realize that the moly particles are engineered small enough to pass through an automotive oil filter. Clogging is minimal. Best, Joe

    PS...going to Honda, to see what they have to offer...and checking molyfusion. Again, thanks. Joe

    I have that stuff at work in spray cans.It comes out like whip cream and turns to a liquid when it hits metal.It is used for chain and cam lube on our forklifts.I have used it to break in camshafts on rebuilt engines.

    I use this stuff, my cousin has used mobil one ever since it came out, he adds this stuff to his oil. he has had gas and diesel.
    It works. when I saw the ad for this I never believe the ads, but this stuff is good.

    I did some research. Toss-up between Swepco and/or Mr. Moly. I'll keep ya posted.

    FYI..looks like swepco has an excellent following, but no container size, or prices on their website. Mr. moly site a little more user-friendly.

    Best, Joe. and thanks to all.
