Question Lubro Moly Engine Oil

Recently, I have purchased a couple 5 Liter containers of the "Lubro Moly 10W-40 MOS2 Anti-Friction Semi-Synthetic" Engine Oil. When I open it and look at the oil, it is very dark (as dark as used engine oil). I have never seen new engine oil as dark as that. Is it supposed to be like this? Any feedback would be appreciated. Thanks

Scott

I do believe 'Moly' is Molybdenum Disulphide - which, if memory serves me, is VERY similar (at the molecular level) to graphite -- hence its lubricating qualities - (slipperiness). The dark color, I believe is 'natural' - nothing to be concerned about.

Yet Motul, which has a huge amount of moly, is either light green (the old version) or normal, light brown.

There are some very strange colors - Brad Penn is like a forest green, Royal Purple and Swepco are a dark purple, redline is red, etc. I think there is a small company called synlube, whose oil is black like dirty oil even.

Out of curiousity, what API specification is the Lubro Moly you bought?

API SJ/CF;
API SH/EC/CF

Wow, that's great. It probably has good levels of Zn and P. I'll have to take another look at Lubro Moly's offerings.

Just remember, high levels of Zn/P are (according to those in the know) detrimental to catastrophic converters (i.e. shorten their lifespan).
Personally I think it's a toss-up -- less valve wear and weaker cats or more valve wear and good cats.

Im not too concerned, since Porsche recommended SF and SG levels of Zn and P up through the 964, and you never heard of catastrophic catalytic converter failures, with many logging multiples of 100,000 mi with no problem. If the emissions controls last 100,000 mi rather than 200,000 or more, that's a fair trade to me :-)

JMHO, but its a LOT cheaper to (maybe!) replace the cats after 100K to 200K than replace cams, rocker arms, rings, and a multitude of other metal parts that suffer from insufficent ZDDP in the oils.
