This is key.!.!.!


"From years working with engine test programs to approve engine oil formulations for API licensing, we can tell you that NO engine oil containing Molybdenum additives has been certified by the full range of engine tests necessary to gain API approval." Bigskye[? I never said this- i quoted this].

This is an outright falsehood. Ther are several API licesned formulators that use moly compounds. Schaeffer's is one that has had API approvals for four (4) plus DECADES.


Now how is it that a couple searches here came up with posts about moly supposidly scrubbing copper.

UOA and Moly

Im only trying to check all of the variables. I already use mos2 in my nissan truck with PP, im just looking for answers on if it will conflict with the amsoil in my race cars- since it seems they use almost no moly. I dont want all of these different add's competing for surface material.

Did you do a used oil analysis on your truck with the Moly added? Was CU high? Red Line, and Motul are two fine oils loaded with it moly, it appears they aren't afraid of loading it into their formulas.

Im not worried about my truck using the PP and mos2- no used oil analysis done. im only at about 300 miles with it, im more curious about the AMSOIL Signature Series and the mos2 counteracting because amsoil seems to think moly isnt good with their oil and long OCI's according to some of their marketing sites. The setup im curious about has a oil pressure driven timing tensioner, which is prone to clogging and seizing.

I understand your concerns now! It is tough dealing with conflicting information. As I mentioned I had checked it out and was pretty satisfied with my findings, but I had no intention of using it with Amsoil. What I have found over the years is this, no oil company wants you to add ANYTHING to their oil. Good luck and keep us posted!

Those same oil companies add moly to some of their oils and leave it out of others. I've always thought the determining factor was cost, rather than compatibility or application. Some oil makers put it in all their products, some may leave it out.

I feel the same way as you. Modern oils are great, however they are blended to a price point too. After speaking with the people I spoke with about MOS2 I'm pretty confident it is a good addition to oil. I've fooled around with the MOS2 in a lawn mower, I have some I coat bullets with. It is Nano particle size and won't get caught up in a filter. Honestly the Lubro-Moly is a whole lot easier. I just bought the Lubro-Moly haven't tried it in anything just yet. The 93 Aerostar will be getting some soon.

The 1987 nissan pathfinder I bought for $800 had 133k from a kid who only used it for a winter beater, and Im sure the owner was about 30k miles past due on the conventional oil. Apon driving it home, I didnt think I was going to make it even a mile before the engine siezed, transmission blew and the wheels flew off (found rear drivers side wheel only had 2 studs (out of 6). I was so excited for the extreme make-over that I called in sick to work! The 1st thing I did was change the oil to Pennzoil Platinum 5w30. The oil was so black that I had to use brake cleaner to remove the stains off my hand. I also looked in the PCV ports on the Valve cover. What I saw was a beach. I stuck my finger in the valve cover, and poked through about 2-3" of sand. Both PCV hoses crumbled like chocolate. Im just VTA as of right now. To make matters worse, he never had a thermostat, so the oil never got up to temp. Timing bel was off by 3 teeth, and distributor 15* over advanced.

The engine ticking/slapping/humming noises were so incredibly loud that I though I was running with a cracked manifold. I ran PP for about 1000 miles before I changed the filter and filled the new filter up with MMO. after about 500 miles the engine quieted down slightly, however still seemed on its last leg.

The MMO almost seemed to thin the oil down too much, and driving the car around in 0* weather sounded like a cash for clunkers video.

After reading about mos2, I added about 1/2 of the bottle to my 3.5qts (which also had about 1/2qt of MMO in it still). 1st day was a light improvement, which mainly I was trying to fight a sound that seemed like a bearing hum.

A week later, the engine is nearly dead silent. I can not hear any bearing hum. Im not sure what happened, but on the downside I did feel a huge loss in power/throttle response. I couldnt tell the car was running at any rpm below 5k as if a sound absorbing blanket was covering the engine.

I can honestly say either it was the accidental overdose (about 8oz/10ga) of MMO in the gas tank (TDI injection) or the MoS2.

I still will hesitate to use it in my performance vehicles with amsoil untill I further look into the compatibility with amsoil.

The MMO or the moly?

wow that thing sounds like it's on it's last leg.

The moly.

Engine sounds good as new now, I could only imagine how much dirt and sludge was in the engine. The difference is night and day. I will stock up on Mos2 for the oil and MMO for the petrol.

liqui-moly gets my vote for now.


Tonight will be the real test. I havent had the chance to take it on a >3 mile trip. Were getting snow tonight, lots of it. I will put this setup to the test with a good hour run mixed with some intense offroading.

Unfortunately, Amsoil, Pennzoil, Mobil, and every other oil company is going to tell you to add NOTHING to their oil. Flip side, every additive maker is going to tell you their additive works fine with any and all oils. One exception is A-Rx, which they say works best with conventional oils and Group III synthetic oils. I think you're on your own here, like any of us who use an additive. Good luck! Keep us posted.

Right they say not to so you buy more of there oil,lol, yes post back after you tried it,i'm not going to hesitate to mine.

 

[demarpaint]

Actually I just checked my Auto Maint Log. The 93 Aerostar is due for an OC in about 500 miles, could have sworn it was a 1000 miles. That puts me a little less than 2 weeks away from changing the oil. I'll add a full bottle them and let you know.

I am glad I am not the only one who feels this way.

I like how on this site people like to say we are not smarter than the people who design oils but they think they are smarter then the people who design an engine and spec an oil for it. It is like don't add anything to the oil but run any oil not spec'd for your engine.

I also think a lot of people run a non spec oil such a diesel oil in a gas engine because they like what is in diesel engine oil more then gas engine oil.

Right more robust

MOTUL 300V - 800ppm MOLY! Very hi level!
I am not sure that it is good for wear level in pistons and piston's rings.

Exactly but if anyone tries to make an oil more robust they are crazy accoridng to many on here. When I feel they are crazy for using the weight oil they are, in an engine not spec'd for it. Will either really hurt the engine, I highly doubt it.

That's because 9000 ppm of moly (colloidal). To get to % you do this math:
(9000/1000 000) x 100 = 0.9%
