Agree....
I was under the impression that Semi-Synthetics are all FAKE, that is any 5W20/30/40 are just highly refined (more than a 10 or 15 or 20W40,50) Dino oils that they Call Synthetic..
A true 100% Synthetic Oil or POA is a 0W20,30,40,50,60..
Am I about the mark???
PAO ... not POA damn n00b 
Polyalpha Olefin
0wXX is a good way to tell if its the real deal.
but some company like Redline, Amsoil and Royal Purple actually tell you what based stock they use. I mean Base stock doesn't mean everything, but if Im paying a premium, I expect premium quality, not some knock offs/cheap ****.

You have a lot to learn my friend.
what is "Mobile" anyway? Is that a new cellular service carrier ?
90% of the Mazda Techs don't know what they're talking about.

Amen to that. I have educated the techs at my dealership on several occasions. And all dealerships use different oils from local suppliers.

Gasoline leaves nearly all of the deposits in the engine. It is by far the dirtiest thing entering the engine. If you ran straight methanol/ethanol/butane/propane.etc you wouldn't have any deposits in the combustion chamber. The only thing a good oil leaves is a mild varnish in the oil pan. This is of course assuming you actually change your oil and filter often. A poor quality oil can leave sludge behind but again it's not in the combustion chamber. Any carbon you see in the intake manifold, intake ports, on the rotors, or exhaust ports are all from gasoline and not the oil metering.
I am contemplating adding a ZEX inline fuel filter (or similar) to the fuel line on the kit just do I can remove the element later and see just how much gunk is in there.

I met a girl once who swore to God she wouldn't leave behind any deposits.....Then it took me nearly a year to get rid of them....!!
Bob tells me oil also carries up to 30% additives some specifically designed to leave behind "deposits", like upper cylinder lubrication for pistons. For rotors, what?

oil additives burn out at or just before 2000 miles, and thats coming from the companies. Unless your running Rotella T which is meant for non cat vehicles. That would burn your cats out in no time though.

i'm switching to rotella t at my next oil change. it'll help that i won't have a cat at that time, too. i've heard/red lots of good things about diesel oil
Do you have a reference for this? The Shell literature indicates that the oil is designed to protect diesel particulate filters and have very low deposits & emissions. Seems like these benefits would also help protect a cat.
Did yall already forget what RotaryGod just said? Gasoline is what leaves behind deposits, not oil... So the reason why we are talking about this is null/void. A oil with "less deposits" doesn't make it a good oil by any means. Stick to a good oil and you'll be fine. The engine will die anyways because of design...
There are other reasons to choose Rotella other than internal deposit control. I'm just asking for clarification as to the statement that it is bad for cats, when it appears that some of Rotella's attributes make it better for cats. The simple fact is the oil's effect on a cat is important in the RX-8.
I like the fact that their marketing material focuses on scientific tests of fleet vehicles, showing a decrease in wear rate of internals. As opposed to, say, a guy in a Kilt telling you to play with your dipstick...
