Simple answer: NO!Will the extra zddp harm catalytic converters?
It's mostly the phosphorus that poisons the catalyst.More complex answer: It depends. If your engine is an oil burner, you will have your cat(s) zinc plated, making them ineffective. The burned oil may or may not clog up your cat(s) sooner or later. Either way, ZDDP doesn't clog up cats. It just makes them ineffective.
Sounds good..Simple answer: NO!

I'm gonna take a wild guess and says that lowering the ZDDP level In motor oil had more to do with putting old engines out of commission and less with saving the cats. Gasoline catalytic convertors haven't changed much during the past 30 years. However, motor oil has!
I can understand his logic. The one qt of RL to four qts of qsud would gain the oci more Moly, Zinc and Phosphorous.Nothing to be gained, something to be lost. Choose the one or the other.
That’s like pouring yourself 1/4 Johnny Walker Blue Label and topping the rest of your glass off with a common scotch. Best keep premium products on their own sometimes.I wonder how good to mix say, a quart of that, with 4 quarts of QSUD?
What's in this oil that would make it clean any better than another brand? Sounds like the ticking may be solved by the moly content. Probably other options to get rid of the tick than by using Redline. Not saying moly's not good but sometimes too much of anything...Killer add pack. Would really clean an engine.
I do it often enough. Redline oil makes a great additive. Add a quart with whatever synth you are using.I wonder how good to mix say, a quart of that, with 4 quarts of QSUD?
Moly is good. And, we see it in the OE Asian fills and their 16 and 20 grades often enough. Its not too much of anything.What's in this oil that would make it clean any better than another brand?

Not at all. This is oil and not drink..That’s like pouring yourself 1/4 Johnny Walker Blue Label and topping the rest of your glass off with a common scotch. Best keep premium products on their own sometimes.
As long it’s the same viscosity nothing really to add or take away. Base oils will be different I’m sure of as would the amount of additives. But from the VOAs seen here Redline slaps any QS product in terms of ppm for zinc, moly and phosphorus but that’s not to say QS makes poor oils, they make some great OTC oils at a great price. Glad you’re happy with your choice.
And for everyone, quit worrying about catalytic converters
Not a fan of oodles of moly is all. What purpose does excess amounts of it serve?I do it often enough. Redline oil makes a great additive. Add a quart with whatever synth you are using.

What’s excess according to Infineum? Or according to you for that matter.Not much according to Infineum, once concentration hits a certain point, at least of the trimer variety, more doesn't do much.

ThanksHere's the paper I presented in the other thread from Infineum:
Here's a good slide from it:

And that graph only concerns THEIR trimer moly... whatever specific product was tested. I would've loved to see them test it at 500 and 1000ppm too. I have no idea what specific product(s) Redline, or the Asian automakers are using for their 400+ ppm moly oils. But, I would wager that Redline, Toyota, Honda, Mazda.... have done their own testing to justify their high moly PPM oil for whatever benefit they were looking for.
