From what I've seen on the UOAs I've browsed over, this seems to be pretty spot on. If I wasn't worried about warranty, which specifies 5w20 dino only, I would likely use Mobil 1 0w40. The only thing that worries me, is that this oil is used in the "Latest engine technologies including Turbo-chargers, Direct Injection, Diesels (without DPF) and Hybrids," so I'm not sure the affect it has on the catalytic converter. Anyone elaborate on this?

What warranty specifies 0w20? The factory and factory extended warranties sure don't.
M1 0w40 is fine for cats. That "(without DPF)" is the key point there. There aren't many diesels without a diesel particulate filter, but those that don't have them can use the same oil as gasoline engines.

Didn't know about DPF - I should look into that for new oils I've come across if I ever decide to switch the brand.
RIWWP - do you know anything in particular about the Agip Eni i-sint 5w40 synthetic oil?
I went to my local store and they were selling the stuff pretty cheap and apparently it is being used on the new M5/6...meets all the newest high standards.
Just wondering if it would be a good option to swtich up to come my next oil change!

The zddp content (zinc and phosphate) is what you have to look for if you use mineral oil. In 2004 the spec sheet called for oil meeting API service SJ . At that time the zinc content was higher than today. This spec is no more available on the market unless you go to specific oil brand that do produce oil for hot rods and antic cars. Those oil brands still have the right level of zddp which is very close to the specified API service SJ . Today, in 2014, there is only mineral oil meeting API service SN on the market for EPA rules and therefore protecting the cat since less zinc is present while the rotors will be less protected, which is not what you want ! You can add concentrated zinc mixed with your today's oil service SN but the challenge with this is to find the perfect receipe to balance with the proper level of detergent.

"Engine starting performance could worsen"?
What about engine running performance, or engine longevity performance?
Am I misinterpreting that?
Of all the syn vs dino debates, I can't recall starting performance being a major concern.
What are the properties of synthetics that would cause that?

Check out the original thread here: https://www.rx8club.com/series-i-tec...il-rx8-147083/
I'm sure the people who made the car know better than the NA counterparts.....
I've been running my car with Synthetic for roughly 20,000~25,0000km and I have an 05 with a non-upgraded starter..that's the 11 tooth starter versus the 13 or 14. I have no starting issues at all, crank time is consistent...actually my car is running better than before. Please note I have the BHR ignition kit, that may have some added benefits to ensure quick ignition.

Much of the discussion of synthetic oil has also evolved. Back when I joined this site there were posts with good information relating the no-synth position to problems with one particular early brand of synthetic oil, and Mazda just not wanting to be bothered with checking them all out. That one oil has been gone for decades, and in its absence the legend and reasoning have morphed.
Not voicing an opinion on the synth debate. I'm just entertained by how stories evolve as the original information is forgotten.

In my opinion the additive package is more important then the syn vs. none syn debate. But... like was said at the top changing your oil often is really the key to engine oil health in the renny. Even the very best oil I have found in testing would not be very healthy with 4k miles between changes.

Been running royal purple 5w-30 for a couple of years roughly 30,000 miles without any problems. I read the original thread up and down many times and decided to go with the purple. This link kind of put it together for me
