Any other combinations?

I was thinking to mix Idemitsu Rotary OIL with Amsoil... for engine oil since Idemitsu is a rotary racing oil. Theoratically, the race oil only last for one race competition and that's why I was thinking to mix with AMsoil.

why is synth in the diff preferred? i have seen plenty of diff failures with synthetic gear oils, no not gear failures due to abuse but bearing failures and in many different make differentials and bearing makes.

....And there have been just as many that fail with conventional......

tit for tat

I supposed it would be "recommened" simply for the basic reasons that make synthetic "better" than conventional, the improved breakdown, less run off, etc, etc.

But really I'd like to take two brand new diffs and brand new trannies one with conv. one with synth. and run them side by side and see if there is enough of a difference that makes up for the somewhat extortionist pricing on synthetic.....

Thanks Motoman,

I didn't change anything interior. Everything came from Original stock and had been 20 years.

It's my baby... Garage Baby~

Meow~

Anyway,

So, Synthetic for Gear or Non-Syntehtic for Gear?

That Idemitsu crap is over-hyped marketing and a waste of money.

So you're saying running synths in the rear diff is a waste of time?

After reading numerous threads on the water trick etc. I went to autozone and picked up a can of Valvoline carb and throttle body cleaner. http://www.valvoline.com/pages/prod....asp?product=52 it took about 15 mins to run half the can through the engine. It smoked out the neighborhood and burned my eyes pretty bad. The result: restored horsepower. It was an engine with 100k on it and compression in the 90s. It ran so much smoother afterwords. Its still running strong and that was last year. After that I swore by it. Ran half a can through my gxl that had a rebuild with unknown amount of miles. I thought it was fast before the cleaning, it loved it. So you might want to pick up a can, but do it at your own risk.
Gave it a try today and I cant say that i'm dissapointed!

You gave a try? How did you feel?

Man, you really "DO it at your own risk"

Pull the stock oil injection - start premixing.

Redline the engine everyday.
This will keep the carbon off the rotors.

i have always had a question about this and wanted to clear it up. usually i do it once a week but i dont rev it in gear. what i mean is, sometimes when im on the freeway goin about 60-70 (its to work DAMMIT), i put it nutural and rev it to 7000rpms - redline. am i suppose to do it in gear? am i suppose to stay in redline for a certian amount of time? how many times should i do it in a day/week/month? oh, and i make sure i drive the car for a while so that the car is warmed up before i do this too. thanks

It doesn't really matter.
It's the speed of the motor spinning that keeps the carbon from sticking.
What I typically do is if you're jumping on the freeway, just redline 1st, 2nd, and even 3rd on the merge.
Be careful as this tends to scare other cars.

I have actual experience using engine flush in my Fd. It's been flushed over 6 times and the stock original engine has over 103k with original turbos and still runs perfect. I recently let the engine sit up for 2 months and purposely tried to flood it with a quick start-up and shut down. It didn't flood and has never flooded. This thread here explains what I did.

https://www.rx7club.com/rotary-car-performance-77/flooding-what-flooding-521685/

Engine flush is designed to completely break down engine deposits and such. It will work it's way through the OMP lines and into the combustion chamber where it will also clean out the carbon deposits. It will clean the engine crud and turbo bearings out which keep the oil system less contaminated. I have not had any problem with using it. If you do start to use it, I recommend you do about 3 to 4 flushes if you have never done it before. 1 flush a week will clean things out faster. Just buy some cheap oil and cheap filters. I spent 10 bucks every time I did it. That's exactly what I did when I started. It's nice to change the oil now and it still looks much cleaner like it was a newer engine.

I change my oil every 5,000km and use and engine flush every 3-4 oil changes. When using the flush the oil drains noticeably better, appearing thinner than oil on its own and running much freer. Getting more oil out of the engine means less crap left in it. So the fact that I can see it doing something positive, and even the stuff from reputable brands is cheap, means I have no problem using it and certainly don't consider it a rip-off. I also see absolutely no reason why it shouldn't be used a rotary. That's just another one of those dumb rotaries-are-totally-different-to-piston-engines myths.

Karack, why would synthetic oil be any less beneficial in the diff than in the gearbox? That doesn't seem to make much sense.

i have noticed some synthetics help with grinding gears in the gearbox, i have seen more differentials fail with synthetic gear oil than i have using standard gear oil. i only speak from my past experiences, people can choose whatever type of oil they want.

I knew a Supra guru who used to run that Slick50 / Teflon crap in his engines.
Claims it didn't do anything harmful, but the valve covers always use to come off slick and clean.
Now we all know about Teflon and engines...
Hint, duPont started to sue companies about their claims of their Teflon in engines.
Yeah, you're right...oil flowing more out of the engine has got to be better...

Btw, thanks for those of you try to answer my questions. I greatly appreciate you guys taking time to answer.

Anyone has any experience with Engine OIL? How about for Gear and Differential OIL? FULL synthetic? Which one? Redline, Royal Purple, Idemitsu, Amsoil?

I went to RX8club.com to do a search. Those are the oil they use for RX8 but I don't know if they could be used for 2nd Gen FC3S.

Any Suggestions? Share your experience? I don't think Rotary God signed up for this forum, huh?
try?

see if i bother "trying" with my input again...
