Hope I spelt it right! But anyway whats the story on this stuff?? I have used it in transfer boxes and differiantals before,but how will it go in my engine as an additive to the oil?? Will it do any damage or will it be benifical,how much should I add ??o No:
Here's an excellent link. A ton of info! http://theoildrop.server101.com/cgi/ultimatebb.cgi Let me know if you find your answer? I know there's a certain type of moly thats safe, Torcos' MPZ additive has it, among a couple others. Of couse there's redline oil which already has a ton of the good moly. Steve
Thanks Steve, heres a couple of answers from the forum over there,one of which came from a guy not far from here as well using the same product as me ,Molybond. I just punched in moly in the search to get some good info it's a good site :beer "Well, we've all discussed molybdenum in oils on this board so much, and it's benefits as an additive in oils...that it will, among other things: Reduce friction Reduce wear So far though, looking at analysis results, and judging by my own experiences, I'm getting ready to settle on using moly oils specifically in one situation: Older vehicle with significant cylinder/ring wear that is consuming oil, and although I haven't tried it yet, new vehicles that consume oil In older engines, the moly seems to really reduce blowby into the crankcase and reduce consumption, "filling" in some of the wear in the cylinder and making the ring/cylinder seal much, much better. Seems to me, running a moly-enriched oil (Pennz. Long-Life 15w-40), in comparison to a non-moly oil (Delo 400), only really results in reduced oil consumption, from minor to significant in everthing from a 4.3L fullsize pickup to a old Ford fullsize gas-engine tractor." And this is the one from here, Australia, " There is a product over here in Australia called Molybond, which is a moly di-sulph additive, particle size less than 1 micron. Comes in a 60g tube. I add it to the oil in my high mileage V8 during winter to stop the occasional knock when I miss starting on the first key turn. It stops the knock. I have just sent them an email asking what the concentration (in ppm) would be adding the 60g tube to 5 litres of oil. I have had no oil filter problems, but with that particle size there should not be. Just turns the oil a nice used black colour. Engine runs smoother" It seems like it's similar to the GM eos product, I have had a bit of smokey blowby recently so I'm going to put some moly in and look at using a slightly higher viscosity oil.It has no ill effect to oil filters.
Molybdenum disulfide If you mix sulfur, water and heat you can get...Sulfuric Acid. :af: As you can guess, this doesn't mix well with bearings. Some additives will use chemicals to block the compound, but would you take a chance? disclaimer, I have no proof, but the formula does work.... we had problems with bearings pitting when we added it to lubricants, back in the 80's. just my 2 cents! :eek2: - Bill
Ruston, I'm glad you found some good info. I did a quick search using "moly sulfide" as keywords; link: http://theoildrop.server101.com/cgi/ultimatebb.cgi?ubb=search;search_forum=5 I just skimmed; here's the impression I got: --moly disulfide powder(MoS2)-somtimes called natural moly-good in grease- isn't the best choice for engine oil because: --------even though smaller than 1 micron it's still a solid --------falls out of suspension and can possibly collect on bottom of pan forming sludge --------can have a possible reaction with bearing materials --moly carbamate(MoDTC)-safe for engine oil because: --------oil soluble --------a stable form of synthesized moly --------the type oil companies use In my opinion MoS2 might be fine, but MoDTC is the safe bet. I'm not trying to push it ; but I have heard good things about Torcos' MPZ additive. It has a ton of MoDTC plus alot of of other good additives. link: http://www.torcousa.com/products/product_detail.asp?intProductsGroupIDPK=120 MPZ VOA link: http://theoildrop.server101.com/cgi/ultimatebb.cgi?ubb=get_topic;f=11;t=000165 More MPZ info link: http://theoildrop.server101.com/ubb/ultimatebb.php?ubb=get_topic;f=5;t=001134#000000 Also using a good synthetic oil [group IV(mobil 1/Amsoil) or group V(redline/motul 300v] in a 15w-50 or 20w-50 weight will help reduce oil consumption because of its' higher flash and evaporation point.
