Mechanical Changes On RX-8 Series I to II

I am using 180 Mils (Amsoil S Pro II) per 60 litres, or 3 mil per litre, which is about 6 ozs per tank.
Yes, I know I have the extra nozzle but I agree with MM, knowing Mazda they again have probably taken the conservative route and cut back the amount of oil metered when compared to Series I, but, I am only guessing here.
I look at it as that little bit more protection.
Ask a Mazda Dealer mechanic about Pre-mix and they go..."what's that", no you don't need that.... Blah Blah Blah.
BTW: My oil consumption is not that high so far, I am still running her in "Racing Beats Guidelines" at about 4000 RPM max, but I have only done 1300KM (800miles), I have given it a few squirts up to 5500 RPM.
I will start to climb more once I hit the 2000KM mark (1200 miles), I always run in my new cars.

4. Run the engine at the specified speed, and note the gauge readings.
• If not within the specification, inspect for the cause and repair or replace if necessary.
Note
• The oil pressure can vary with oil viscosity and temperature.
Oil pressure (reference value)
350 kPa {3.57 kgf/cm2, 50.8 psi} [3,000 rpm, Oil temperature: 100 °C {212 °F}]

Series-II chassis drivetrain
Front cross member - foam filled as per 07 run out models (40th Ann version)
LSD - Revised design
Gearbox - Revised design (aka NC MX-5)
Gear level - shorter throw
Wheel/tyre combo - 18" = 22.7kg - 19" = 21.4kg
Steering control arm - link assy raised 7.5mm
Underbody - additional paneling - CD reduction to "0.30"
Shocks - Type-RS/GT Bilsteins, revised mounting points
Visual changes are well known now & easily spotted.

Also has the Recaro Seats (that are Not Electric), no leather inserts.
Front Aero Bumper that has a more sculptured look and side splitters.
No Electric Sunroof
Side Sill Skirts
Rear Spoiler

All of the oils, which are preferred by Mazda has to reach the reference pressure value (212F,3000rpm). If it's not true, they don't know what they say (at Mazda). I hope they are not idiot.
...and the preferred oils ( at all of the diff. parts of the world) for the new renesis by Mazda:
Grade API SG, SH, SJ, SL
ACEA A1, A3, or A5 API SG, SH, SJ, SL API SG, SH, SJ, SL, SM
ILSAC GF–2, GF–3, GF–4 API SG, SH, SJ, SL
ILSAC GF–2, GF–3
Viscosity (SAE) 5W–30 10W–30 40, 30, 20, 20W–20, 10W–30, 10W–40,
10W–50, 20W–40, 15W–40, 20W–50,
15W–50, 5W–20, 5W–30, 5W–40 40, 30, 20, 20W–20, 10W–30, 10W–40,
10W–50, 20W–40, 15W–40, 20W–50,
15W–50, 5W–20, 5W–30
Remarks Mazda genuine Dexelia oil e.g. — —
There are xxw-20 oils.
Strange, but as I looked after the preferred oils info, I found a sentence on the site (You have to know it's the freshest european service info site.) :
• Because engine starting performance could worsen, do not use either synthetic or semi-synthetic motor oil.
..so I have to say they don't know really what they say!
As we know there is on the market their new full syn 0w-30 oil for the Renesis. More strange that we can't find the 0w-30 oils in between the preferred oils.

Please lets not talk about OIL GRADES again, there is enough oil information already in this forum.
Thanks for the info though..

sure mazda knows all. they made the engine. what do I know ...

next thing I know is that if u use Synthetic, they will tell us to go buy a civic.
Anyway, Series II's sale is pretty bad. Hmm, if I go trade in now (when Im back to NYC actually), will I get some exceptional deal ? say, 5K under invoice ?

I know your opinion RG. I'm on 0w-30 since 2004.
That changed! The Renesis II has brand new oil pump.
they will NEVER get a 70 oil pressure at 212 F and 3K out of a 5w/20 oil!! Never--unless the system is major changed!

1. It would be good to know, why they raised the oil pressure?
a,Were there bearing wear issues with the lighter oils ( xxw-20)?
b, Or did it for the better cooling? As we know if the oil flow is higher, then the oil and the engine's internal parts would be cooler.
2. Also would be good to know did they raise the bypass valve's opening pessure? I don't find this data. If they raised it too, i think the reason was the "b,": the better cooling.

Yes, there have been many Rotor Bearing wear issues (Worn down to copper sleeve) seen in rebuilds...
Many here think it is the 5W20, the 20 being that the grade of oil is too thin for high temps, better to use a 5W30.
IMO a higher pressure oiling system would move the oil quicker/faster/stronger, therefore moving through the improved oil coolers quicker resulting in lower temperature oil which has to be a good thing.
Fred, RG, may be able to verify my view, or correct me...
Again I prefer not to start an oil grade discussion again here or synthetic for that matter.
Just on the reasons for a higher oil pressure system.
I will try and get a reference (Mazda Part Numbers) for the Oil Pressure By Pass Valve to see if it has changed, IMO I think it would have.
It appears that there are Many, many changes (more than I thought) to the new 09 RX-8.

2. I only find the REN I. oil bypass valve data. It opens at 78-92,5 psi.
As we discussed earlier there had to be min. 50,8 psi oil pressure at 3000 rpm, 212F.
Now the REN II. reference data 72,5 PSI, 3000 rpm, 212F. As we know the average oil temp is lower than 212F, so we would reach too early the bypass valve's opening pressure, with the "old" bypass. From this reason there has to be a new bypass valve with higher opening pressure, if they really want to improve the flow at high rpms!

i always wondered, if the fuel system is returnless, was it imposible to add metered oil supply lines to the fuel rails and just forget the oil injectors?
it would be like high-tech premix!
