How many are using engine oil with Antimony?
The Mustang GT 5.0 engine at 170000miles did react very positively to the addition of 200ppm of Antimony, the most spectacular is the usual TIK that totally disappeared...I am tempted to try the Schaeffer 9000 5w30. I will value comments and opinion...

kschachn, re-read, no words or intent to debate about your Fav Redline lub, questioning about Antimony from RLI Booster Pack​

https://renewablelube.com/assets/fi...I3TVp5Li3ITXMGv1IMOjfZ_7XRT1ew78CMao0oTWAL_so

Antimony is a great high-pressure additive and should be used only for non emissions applications but this is funny looking to me because the booster pack is sold in an 8oz bottle that's 21.40 each.

8oz is 5% of 5 quarts and if you want the best performance you need to buy 3 or 4 of these $22 8 oz bottles so that you can treat 5 quarts of oil.

I believe the 5.0 has a 10 quart sump so that'll be 6 to 8 of these which is 129-172 dollars just on oil additives alone. Sorry but hell no. I'm simply buying hpl supercar or something else instead and it will likely perform better. Given that these are spec'd for crappy ford syn blend 5w-20 anything is an upgrade and short intervals with something like better esp 0w-30 or mobil 0w-40 will more than suffice especially if it's not going to do more than 400k in its life.

Somewhere I got the idea in my head that Liqui Moly Molygen (green lizard blood) was using antimony. As a matter of fact, I recall calling the lab I use, being Polaris labs, and asking them about it. Polaris doesn't test for antimony, so I just dropped it. Any of you know a lab that does test for antimony?

Hi GI_, Blackstone is checking for Antimony if you ask and pay for it, this is the report for the Booster Pack RLI container in the picture

How long ago was that? The sample report on their site shows it as one of the report items, and Oil Analyzers (same place AFAIK) has it on their reports too

It seems to me that if the gallon contains 7269ppm of Antimony measured by Blackstone, this is a good price if your intent is to load 150/200ppm Antimony in your best available oil...but hey, what do I know?

Why would the "best available oil" need "improving"? The odds of Joe Average being able to dose a premium fully formulated oil with some wizard and yielding a superior end product are spectacularly remote.

When a lubricant is developed to create a synergy with a specific engine for specific conditions, nothing hurt to work on enhancing the lubricant abilities if there are none fitting the needs for the engine you use...200ppm of Antimony addition is not a lubricant development that requires a real lubricant development...
Long time I didn't post on here...

If you’re not a chemist then don’t play one at home…
 
Oups Patman, I have a group of full-time paid chemists Tribologist I am working with in my companies since the late 70's, since more than a decade I have been around I was thinking you did look at our website..., there are very respectable Tribologist here on I respect the required amount.

Oils are a balancing act, performance improvement in one area can negatively impact another, this is why extensive testing is done to ensure the efficacy of formulation changes and component selection. Dosing that carefully balanced chemistry with another component, be it an EP additive, FM, thickener, cleaner...etc. WILL have an impact on the performance of the product, and the odds of that impact being overwhelmingly positive are impossibly remote.

This is something I've discussed with Dave at @High Performance Lubricants quite extensively. Each additive package and base oil blend responds differently to different FM compounds and compound combinations. While a full-SAPS A40 additive package in a 0W-40 might respond best to a 60/40 blend of trimer/dimer moly and not respond well to additional augmenting with say titanium, an API SP/dexos additive package might respond best to a 10/80 blend of trimer/dimer moly and a 10% dose of titanium. Or a mid-SAPS C40 additive package in a 0W-30 might respond best to a 80/10 trimer/dimer blend with 5% tungsten and 5% antimony. I'm pulling these numbers out of my posterior, but the message here is that different suites of additives, in concert, respond differently to additional components and the base oils, PPD's, VII's and other components also influence this. That's what full formulation is all about.

Now, you are less likely to see some of these compounds used in OTS lubricants due to cost, and it's not unusual to see the same additive package recycled across different grades and base oil blends also due to cost. TEOST restricts moly use for example, as we've recently discussed, but in the context of your "best available oil", these restrictions and cost cutting aren't in play.

You didn't provide a link to a website, how is he supposed to have looked at it? And what company is this?
