Amsoil claims Moly prematurely clogs filters

[Motorbike]

A friend sent me this link and was worried about what he read down in the second to last paragraph where Amsoil is claiming that moly prematurely clogs oil filters .

Does this really happen or has this problem been detected in a test procedure of some type ??????

Pulled from the website :

Try the AMSOIL 0W30 which has a 35,000 mile or 1-year guarantee. If you stay with the 3000-5000 oil change you will not; have high temperature protection, save gas, save money, reduce wear, eliminate engine deposits, maximum filter life (moly based synthetics prematurely clog filters - Amsoil is not moly based).

First off that is not an official Amsoil site.

I've been an Amsoil dealer for over 5 years, and I have never read any official position on Amsoil/Moly/and filter clogging.

Secondly, I'm sure there are thousands of customers running Schaeffers with not filter clogging.

I can see teflon getting trapped by filters, but the moly used in motoroil is not able to filtered out, even with submicronic filtration.

Your largest chance of filter clogging, is from Oxidation of the oil leading to sludge getting trapped by the filter.

Amsoil is a very high detergent oil and would help clean out the sludge which would lead to premature filter clogging, (same with auto-rx)I've seen no evidence of moly doing this.

Is oil thickening due to oxidation one of the precursor's to sludge build up ?

Too funny,

This Amsoil Dealer (Non-Sponsoring mind you) just thinks he knows it all.

What matters that this above example does not show is the TBN once the oil has been in use for 10,000 miles. I have done independent analysis as seen elsewhere on this site at extended mileage and AMSOIL stays consistent thus the Guarantee! See Mobil 1 Data Sheets and compare yourself. Have your Mobil 1 Analyzed at 10,000 miles and see for yourself where the viscosity index remains.

I wonder if he has followed the Spacebears project? I've seen many analysis with mobil 1 running 10K.

I wish these goof's would drop off the face of the earth.

Of Coarse, hence the reasons why synthetics excel at extended drains. The higher the oxidation resistance (look at HT/HS Vis) the longer you can go without the oxidation factor building up in your engine.

But it can happen with any Oil including Amsoil if you run long enough (or hot enough).

For instance the Amsoil ATM something like a 5% loss in the NOACK Volatility Test compared to a conventional that is 10% plus. So while they will both thicken(due to oxidation) the conventional will do it at least 2 times as fast.

Of coarse in the chart that Amsoil uses they only compare the ATM to conventionals not other synthetics. I'm sure most of the group IV plus and to some degree group III bases the NOACK is at least 50% lower compared to a conventional Group I and II base.

Yes, it is...although you REALLY have to abuse a good synthetic oil, whether it be AMSOIL or Mobil 1 (or any of the other TRUE synthetics), to get it to oxidise.

Like msparks, I've never heard of moly clogging an oil filter, either...at least certainly not with any commonly available oil. I think that person was confusing moly with Teflon.

 

[peterr]

Or perhaps he is confusing soluble moly in current motor oil additive packs with solid particle moly in suspension?
In the past i think moly suspended in oil was a popular "mechanic in a can" formula. Here in canada we still have MolySlip, which I beleive is such a product. Probably a better idea than teflon in your engine, but maybe not a great idea.

In any event it is hard to take the "Moly is bad" suggestion seriously.

And I think the person is just "confused" all around.

Another "well informed" Amsoil dealer.

looks official to me.

Even the big headline is incorrectly spelled.

 

[Spector]

What is sad is that he does a disservice to the good dealers out there and Amsoil corporate does nothing to police the use of their name. The good dealers are fighting an uphile battle due to the poor marketing hype of the few!

 

[Pablo]

I want to officially go on record as to: Amsoil does NOT claim SOLUBLE moly clogs oil filters........

I will go on record to state I added a can of MolySlip E to my crankcase and within 2000kms the oil filter was plugged.

The oil pressure gauge on the dash was PEGGED. And this is with Esso XD-3 0w30.

When I removed the filter, the oil that came out of the filter was light gray with moly.

I had to perform a complete engine flush WITH new junk oil just to purge the system of this crap. It was HORRIBLE!

Even after the full flush, the oil was black as tar from this crap.

Needless to say, I will NEVER do this again!

Blaer LT - good POINT!! (and good post)

These guys have completely overwhelmed all the search engines too. Almost any search with any lubrication term gets you thousands of Amsoil dealers and not much else.

-amsoil -amzoil added to the search terms you are interested in is your only way out...

I think your experience is fairly common up here in the great white north. To my knowledge this product is not sold in the US, and I don't know if they have anything similar. PTFE seemed to take its place, in formulations of Snake Sludge (how do you described a snake Oil suspension?)

If the filter was clogged wouldn't the bypass have relieved the extra pressure? Or even the pressure regulator?

This is not the same type moly that ChevronTexaco, Pennzoil, ExxonMobil, Castrol, Schaeffers, etc. put in their oils.

Yes, this is the point i was (trying) to make.

This independent Amsoil dealer site was confusing Particulate moly in suspension (bad) with soluble moly (good).

Blazer's experience is with MolySlip, a product that is of the bad Moly variety and seems specific to Canada. I almost bought some myself once, but my recollection was that the package actually said something like "suspension" that scared me off.

Maybe I missed it, but it needs one like on mine:

Nice site.

But, what is a "fitment"?
