Flashing Oil Light
2010 R3, was teaching gf to drive stick...wasn't going brilliantly (ran the gambit of stalls, bucking and wheel spins)
After about 20 minute or so the oil level light started blinking. (no beep like when oil level is low).
Stopped and checked oil-looks good, pretty much at full. Changed by Mazda dealer about 1k ago.
Light goes away after restarting,
Decided to check the manual and it read that when the light continuously flashes to not drive vehicle hard and get it checked by dealer. Noted that if vehicle restarted while flashing due to malfunction it may take the light a few minutes to start flashing again
Drove it on 3 short trips after that (5ish min), no light.
Thoughts?

Yes, be careful and monitor it very, very closely. Keep an eye on the level often.
I'm hoping your girl, just didn't like the other girl attempting to tell her what to do and abusing her
Don't let the GF try it again for awhile.

From the OEM documentation, oil light only flashes on an OMP problem. Scroll down about 2/3rds, I highlighted the rows.

i'd reset codes and see if it comes back. OMPs are quite spendy... unless you can find a good used one.
Edit: This is a Series II, completely different MOP's to any other RX- made before by MMC...ASH8

I suggest it is 'blinking' because oil level is low, even though it was changed 1000k ago.
You know Rotaries are meant to use oil and requires topping up regularly?
.Checking oil quickly (side of road) is not the correct procedure, get car on flat level surface, 5 minutes AFTER engine turn off, check oil level.
If a blinker persists, then go back to a Dealer and or get codes read, IF they exist see RIWWP post.
EMOP's in Series II have not been known to give issues...at all...yet.
Could be OCV too.
But check Oil Levels first Correctly.

Also.. might be something to do with.....
I guess by GF?
Oil in sump pan may have been sloshing around too much from all the "bucking", particularly if Oil level is low, starvation could of occurred.
Remember Series II also has it's only Oil Pressure Sensor located on one of the two EMOP's, so IF oil pressure is low this will set off Blinker, it is the only sensor that will cause blinking...apart from the Oil Level Sensor in Oil Pan.
Also every time car is started after ''stalls'', EMOP's injects a small amount of engine oil for lubrication.
I still believe your oil level is low.

Update:
1st: I forgot to mention that I pulled codes after restarting (keep an OBDII sensor in my glovebox). No codes.
2nd: I left her idling outside of a friends apartment for 25 min or so and the light did not reappear. Turned it off and went for a 20 minute drive shortly therafter, no change.
Oil level isn't the issue. Sloshing would be my guess at this point. Mostly likely confused the sensor as some of the starts/stalls were....harsh.
Further notes: the R3 is my 3rd 8, so I'm well familiar with the oil use/ general rotary quirks at this point (hence why i keep an OBDII sensor in the glovebox...). I check oil every(ish) fill up and that's not the issue here. Oil was checked in gas station about 75 miles before attempted stick driving lesson. Stick driving lesson was in level parking lot, we swapped locations immediately after the light started blinking and I drove it a bit before restarting it, then pulled codes after returning to said parking lot and checked oil after sitting letting the car sit a touch longer.
Its a 2010 but the original purchase date was in August of 11 so there's more than a year remaining on the bumper to bumper.
I'll keep an eye on it and provide additional information if there are any further developments.

2009 RX-8 Touring
The RX-8 has to be the worst car to learn to drive a stickshift. The clutch is like an on/off switch, the engine over-revs really easily but produces almost no torque at low RPM, the shift lever has no bushings to dampen distracting mechanical sensations, etc etc etc. I went from knowing the basics to being a good stick driver in my RX-8, but I wouldn't put someone else through that pain, not when there's a nice easy Honda Civic floating around somewhere.
Anyway, it seems most likely the error was captured during a stall.

I would not recommend a used pump. Very risky indeed. I tried it and lost. It was only a hundred dollas or so but it added to the cost of my new one which was around $1400.00 adding my used mistake into account.
Things brake even with the best of care. The omp is pricy and probably the best wepon against break downs is maintenance, maintenance and maintainance.

Very old thread, but series 2 cars getting older so maybe new failure modes:
On my car the flashing oil light came on after topping off the oil. The fill was without a long neck funnel so maybe that's a clue. Now there's a persistent high amount of smoke coming out the tail pipe (a lot) and the oil warning light flashes. However, when pulling codes, I can't find the ones that according to the FSM, should accompany the flashing....so a big mystery to me as to what's causing the flashing (and the smoking). I measure oil pressure at the PCM and it seems to move linearly up with engine speed. The improper fill may have clogged things because I got codes for the SSV, Secondary Air Pump and the O2s are fried thanks the the amount of smoke.
Don't know where to go next...FSM not helpful at this point and I'm finding very few S2 experts that can help diagnose. Some conclude internal oil seal issue due to the amount of smoke but I still can't move on from the flashing oil warning light and what's triggering that.

Posting my update in the interest of helping others in the future:
So after trying 4 different scanners (including Torque app), I was still not finding one of the OMP DTCs that was supposed to accompany my blinking oil warning light....so nearly ready to send to dealer when I decided to give FORScan a try. Ordered the right HS/LS adapter for current Beta version and voila, it pulled the DTC I expected. P1680.....so lesson learned is none of old diagnostic tools pull the new S2 codes but FORScan does.

Well, short story is that is was a blow fuse found through the code I mentioned above.
Long, story (given my engineering background), is that the engine fails-safe. It has been a while and I got rid of the RX-8, but i think I recall that the S2 had two oil pumps so more pressure than the S1s. With the fuse popped both pumps went to max pressure. I forget what sensor or signal regulates the pressure but that circuit was the one hosed by the fuse. What S1 owners could not believe is that the over oiling could produce the ridiculous amount of smoke that I was seeing....it was so incredibly. There was a quart of oil in the exhaust when we cleaned it up and took it off.
Good luck.

S2's does not have 2 Oil Pumps for engine oil, it does have a different main Oil Pump for engine over Series 1 and is not the same unit (under the front alloy Timing Cover like all rotaries).
You may be thinking the S2 MOPs (Metering Oil Pumps) and yes there are two different alloy/electric solenoid modules next to each other (see pic above) for squirting engine oil via 6 injectors into Rotor Housing to lubricate Apex, Side and Corner Seals (S1 is a different single MOP via 4 different Injectors).
No other RE uses the S2 Oiling System which is also cleaned and flushed via PCM/ECU, not same as S1.
IMO Mazda left the best system in the last RE every made, interesting that a S2 Fuse should blow, why?
You may be thinking the S2 MOPs (Metering Oil Pumps) and yes there are two different alloy/electric solenoid modules next to each other (see pic above) for squirting engine oil via 6 injectors into Rotor Housing to lubricate Apex, Side and Corner Seals (S1 is a different single MOP via 4 different Injectors).

I found this thread that pointed me to which fuse to check and a possible reason why it may be blown:
https://www.rx8club.com/new-member-f...xhaust-263879/
I just went out and checked my "EGI Comp1" fuse and sure enough, it's blown! This fuse is a 15 amp located in the under-hood fuse box. I just bought this car, knowing it was smoking and had oil coming out of the exhaust. The woman I bought it from said she had recently had a new catalytic converter put on. I'm wondering if the O2 sensor wires are melted and shorted somewhere, as described by member "rbti" in the link above.
Fingers crossed that this will be the fix.

Posting my update in the interest of helping others in the future:
So after trying 4 different scanners (including Torque app), I was still not finding one of the OMP DTCs that was supposed to accompany my blinking oil warning light....so nearly ready to send to dealer when I decided to give FORScan a try. Ordered the right HS/LS adapter for current Beta version and voila, it pulled the DTC I expected. P1680.....so lesson learned is none of old diagnostic tools pull the new S2 codes but FORScan does.

Could you take a picture of the scanner? I’m trying to get one that will work on my car and when I look it up it shows a lot of them
