Molybdenum Disulfide
Folks: Do any engine oils contain moly? If so, which ones?
Have you ever added a moly additive to your oil? In Canada we have Molyslip E, aka Mr. Moly in the U.S. Did it do any good for your engine? Any obsevations? Thanks!

Considering you are asking about moly DISULFIDE, it is no longer used in todays motor oils and hasn't been since about the sixties. The Moly of today is in the form of molybdenum trialkydithocarbamate better know as MoTDC. The old disulfide had problems with the crystal size being too large and being filtered out and it couldn't be held in suspension and ended up as goo on the bottom of the pan.
So the question is, are there oils with MoTDC in the formulation? Yes, with Redline leading the pack on having the most content. Moly is an anti-wear agent as well as an anti-oxidant. It is also a functioning friction modifier and a metal deactivator which helps in reducing oxidation of oil. It is a good additive to have in your oil but before you go and add a bunch, it can upset the add pack balance. If you need the moly for the barrier lube in your engine, use either Redline oils or use the Redline as an additive. Usually one qt of Redline will have as much moly as 5 qts of Chevron Supreme. Hope that answers your question.

Makes sense to me. Thanks. But it is ok to add a quart of Redline to my regular oil is it? Any other thoughts?
Hey TallPaul, are you the same TallPaul that posts on the Noria forum, or has some else got the same name?

I have run redline mixed into Maxlife and currently have half a quart mixed with Napa synthetic in the wife's Aerostar. Flash says it's ok to mix and that is good enough for me. Oh yeah, Dave at Redline said there would be no problems mixing, but of course he felt you are better off running straight Redline--of course!

Nope . That is a balanced mix of additives in it'self with a carrier capable of holding it .
Throwing balance off would be more like finding calcium only and throwing 10,000 ppm in your oil . Same with zinc
When I first started playing with the Valvoline Synpower additive almost two years ago I was amazed at the lower iron and TBN bump it gave . It has worked very well for me at 1 ounce per quart dosage in a 3.0 Ford and it's not due to the moly thats in it . The oil I was using already had over 100ppm of it to start with .
