Received this email from Maxima racing oil that says it will answer technical questions. I haven't utilized it and just recently heard of this brand. Seems to be oriented toward racing but does sell boutique ester based PCMO too. Here is the site for questions:

Wonder if the oil would work on an autocrossed 370Z nismo too smile


Thanks but I don't want to bother racing guys with PCMO questions.

I found my QSUD 10w30 magic juice.

It appears that their oils have super strong additive packages that may be too much for modern catalyst systems. That is the question I asked them. What the upper limits of moly/phosphorous/zinc/calcium etc are before harming modern pollution systems.

Any CAT harm only comes if your engine is consuming oil. No consumption, no harm because there is no partially burnt oil going down stream to the CAT. LOts of us have been running heavily dosed HDEO oils in passenger cars for decades, and our CATs last well past 200,000 miles and the engines pass SMOG testing just fine. It's not really a worry.

If, however, your engine is burning oil at something in excess of 1 qt per 1,500 miles, you will both ash cap and kill a CAT. Been there and done that too ...

Was there a time when they refused to answer technical questions that makes this something new?

Don't know. Received the email a few days ago and was only aware of the product recently.

i have seen their motorcycle oils advertised + discussed. they don't hide their blend oil % noting 50% ester in the blend. i don't expect full disclosure but when blenders like Amsoil answer NOTHING they are surely hiding "something" likely that they use cheaper base oils than in the years past but still charge $$$$. i like to know what i am paying for!!!!

Where are you seeing that? I've never noticed that 50% ester statement before.
