Which 5Wx30 or 10Wx30 synthetic oil in the U.S. market today has the highest amount of effective* moly?

* Effective because some may compare tri-nuclear vs. regular? moly!

Also doesn't need to be d1g2 or d2.
"Thickies" may think of TGMO 0Wx20 but in 5Wx30 or 10Wx30

Thank you!
 
By doesn't need to be d1g2 or d2 I meant it doesn't have to be ... it is ok either way.
 
go to PQIA and have a look.

shaeffers9000 and QS seem to like Moly?


TGMO is also above average.

true.
got 10 times more moly than the m1.70 vs 700 if i recall correctly.
came back from the dead see yesterday,it was 30 min of 3rd gear uphills in 40 Celsius,i was very glad i have the rl in my motor.

I toured Colorado last fall and had the same conditions off and on for 3 days. I had M1 0-20 in my Ford engine and it performed great with no oil consumption. Folks that live in the mountains of Colorado pull these mountains daily without problems.

A lot of PQIA is obsolete since the formulas changed with SN+ and dexos1 Gen2.

I think their formula is still the old high-moly, high calcium, and high sodium formula, bad for direct injection and/or turbos, not SN+ dexos1 Gen2.

Just for their latest 0w20, not xw30 that the OP is asking for.

Amsoil SS 0w30 or 5w30 has high-ish moly. ~200 ppm, and the "usual" amount is 75 ppm for comparison.
Somebody siad Mobil1 above? No. They have the usual 75 ppm amount or so.
Redline for sure, very high moly, go with that one if you must have moly.

No it cannot be invisible if it contains the element molybdenum. The plasma temperature of an ICP (or AA for that matter) will decompose any compound and show the constituent elements.
 
No certs needed? Redline. Schaeffers and Amsoil are also good options which contain high moly and can be had for cheaper than Redline (if that matters to you).

Certs needed? From what I've seen, QSUD is the leader and can be found extremely easily and at a great price.

A lot of the popular, high moly oils such as TGMO, Idemitsu, etc, only have the large amounts of moly in the 0W-20.

They do, but the difference in add pack is noticeable. The XL and OE oils have moly at around ~75 ppm, similar to M1. The Signature Series is the only lineup with higher-than-average moly concentration, and it's not certified.

600-800 ppm moly, per my conversation with them. Last reformulated in 2014, so well after the introduction of tri-nuclear moly. And moly will be more efficient in this oil because its detergent levels are pretty moderate.

If you want healthy anti-wear and a ton of FM, and are willing to run moderate OCIs, xW-30 oils might not get any better than this.
 
I mean, it's not going to be "unsafe." Certainly not worse than running a diesel oil in a gasoline engine, which so many people apparently love doing.

I did ask them if they agreed with my hypothesis that this oil would be great for piston engines. They seemed to agree in theory, but couldn't say for sure either way because they haven't tested it.

The base oil is majority PAO with some ester, and conventional additive carriers. They make no claims about rotary-specific ingredients, for what that's worth. It seems like a normal high-end(-ish) PCMO, just with the additives in different proportions from normal.

Yea but most diesel oil is also SN rated, so that means it's technically perfectly fine to use and the extra diesel soot fighting additives will probably keep a non diesel engine chrome polished inside. Haha.

Since Rotary engines use regular engine oil, I suspect a Rotary engine oil in most likely backward compatible to a regular engine. All those extra wear fighting additives should do wonders for a piston engine. Whether or not there's any actual decreased wear vs your average Lube is questionable... but one can certainly hope for the best.
 
Not all moly is created equal. A higher number does necessarily mean it is more effective as an anti-wear agent.

True. The law of diminishing returns comes into play at some point. Yet the questions keep coming.
