yes, sohn adapter. It has been discussed at length, and it is a very good idea.

 

sounds like a lot of down time and testing when you can just mix it when you fuel up.

 

I asked RE Amemiya about premixing a while back, here's the email they sent me:

"
Dear customer

Thank you for your e-mail.

Adding 2-stroke oils is sometimes required.
That depends on the engine mods.
And depending on the track use or just a street use.

If your motor is completely stock and you don't run on the track, 2-stroke oil is not necessary.

Regards"

 

If it was not "Necessary", then why was it necessary for Mazda (The Makers) to re-introduce a middle oil weeper to lubricate the MIDDLE of the APEX SEAL in 2009~ RENESIS II.???

GAME OVER..

 

I dropped OMP rates by 1/2 and use about one litre of sump oil every 5000 miles .
To make up for the low injection rate I also premix at the rate of 200:1 .
People on here have crticised the way I do it but to me it still makes perfect sense .

 

^ yep.

 

I did notice that my fuel filter was black as and there was a layer of film all over my pump housing when I changed the pump recently . Was not affecting fuel delivery though .

 

9krpmrx8,

Yeah, that reminds me.

Can you get to the screen in my old pump to check for crap?

By the way, I'm coming over tomorrow the 30th at 5pm after I get my car!

 

even with the S2 3 injectors, I will still premix. simply because 2 stroke stuff lubes better.

some ppl think its pita to do it every fill up. I just wanna say if u can't handle that extra 30 seconds at every fill up + that extra couple of bux of premix.. then you shouldn't even drive a Rotary.

/end

 

Do you have this planned in the near future?

 

I cried myself to sleep with the knowledge that I must now give up my 8

They said that pre-mixing was ineffective. You're comparing that to the direct lubrication of the apex seals.

 

Yeah, so ineffective that you could remove the OMP and run solely on premix!

 

yes, I strongly agreed.

Please sell your 8.

 

Yes, I will get pics of it and post them up this weekend. Sorry I missed you Tuesday man, my cell decided to die so I spent the afternoon dealing with T-Mobile and ended up being without a phone until Wednesday.

 

THEY, who is THEY, I was directly quoting what was posted, and NOT by you.

Where does it say ineffective???, I read "not necessary".

What the hell do you think Pre-Mixing is for??..

Do you know of ANY other way to Lubricate the Middle of your Apex Seals in a Series 1 RX-8??

 

No sweat man, I'm just very happy with my car and wanted your opinion.

Your plate is definitely full; I'll try to catch you on a run sometime.

Also, post up your 5w40 and 0w40 oil analysis. Ok?

 

dont forget to take a towel!!!!

translation dont forget to premix the oil you are going to dump into the tank..

but what do i know.

beers

 

-Grace: Did you clear the CEL? How is the premix doing? You're still at 140,xxx? : )

 

Where do you guys buy your 2-stroke at? I am pretty sure the Autozone down the street will have some, I just wasn't sure if there was a better way to order it cheaper online or such.

 

I ordered my last case of Idemitsu Premix from www.rx7.com

Alright, I will keep that in mind. Are there marks on the side of those bottles to measure ounces?

 

I have been throwing this back and forth in my head for a while, read this thread (alot of it anyway). As much as I know the sohn adapter and premixing would be the ideal conditions, but since I am pretty positive that the sohn adapter would void the core warrenty and I can't afford to rebuild the motor on my dime right now. I have to decided to start premixing to at least help the situation. The issue is there so many opinions of ratios. I am running catless so a high ratio would not be an issue there, but I know that too much oil can be a bad thing for the internals. I was thinking that a ratio of around 600:1, as RG and a few other have suggested. I was wondering if this would be enough to do the job, or should I increase the ratio (and leave/change pump rates) OR should get a compression test and if the results are good go ahead and buy the sohn and start premixing? What are your thoughts as this has been on my mind for a while.


Notes about my car: 2007 M/T bought used with 44,xxx, with decent maintaince records, regular oil changes since then every 3k, currently almost 55k on the clock.

 

My humble opinion .....
600:1 is not enough to do squat
200:1 is what i would recommend (been doing it that way for 50,000 miles) - makes it really easy to work out how much to use
I also knock back the amount of OMP injected but you don't have that option .

 

Just started poking around in here again. Only on page 7 right now, but I read the last few pages too. As far as doing a SOHN adapter, and premix... Why not, especially on a series I engine? Mazda increased the OMP duty cycle on the series II didn't they? So if you are running 2 stroke through the OMP, and run premix, it'll help lube the center seal. Plus, you'll still have the benefits of running two stroke in the CC.

I plan doing premix and the SOHN adapter when I do get an RX-8 from what I've read so far.

 

You know how the Winter season brings the worst of our car? In the last three days I started having problems starting the RX-8 if it's very cold outside. The same if one floods their engine, I don't go through the procedures as the engine turns over after a few starts.

I don't go out for short drives and I've always made sure that the engine's warmed up before going out. It feel like it's fuel starvation or bad coils, so I've hold off premixing with the assumption that my fuel pump/line/filter or CAT could be clogged. What ever it may be, I'll have to check all these next week since the car hasn't preseted any CEL.
