Did you folks know that many synthetic oils are dinosaur oils that are run through
a process that crushes the oil to cause uniformity in the oil molecules.Whenst you do this,by law you can call it synthetic as you have a man made process or synthesized the elements.The best of the best IMHO Amsoil bought the crushing machine to make a lower cost oil.It is the labeled xl 7500.The rest of their other oil
is ester bases or PAO which is a man made synthetic base stock which may not work well in a wankel engine.I have discovered than many of the major oil companies that market synthetic lubricants use the crushing process on all of the oil they market.I will not mention their names but you can find a court case on findlaw.com Mobil vs Castrol that can shed some light on what is going on and are we the consumers being duped into buying at a high price an inferior synthetic.
I believe these inferior synthetics will work great in a wankel as they are essentilly dino oils that have been re-engineered.

 

ok I havent posted on this board in a while, but i have to say my peace about synthetics...
I have run Redline synthetic 10w-30 in my stock 12a for over 60k. Everyone was telling me not to because of burning and guming issues.
I cracked the motor to rebuild at 136k, and the apex seals were as clean as a whistle. no guming, and no more carbon build up that is absoutly normal.
And ohh yea, I didnt rebuild because it needed it! it had fantastic compression all the way around. just flet like going with a mild streetport....
I will forever run Redline in all my vehicles.

 

I ran royal purpal in my 1st motor. Did good. I am in the breaking in stage of my new motor but after it broken in I am gonna run either redline or royal purpal.

 

Running Idemitsu...No problems yet..

 

Amsoil, started on a 125K engine now at 160K and uses absolutely no oil. I change it at 7500 miles per manufacturers recommendation

 

I run Redline in everything I own, except the RX.
It gets Idemitsu synthetic.....not that I think Redline might be bad,far from it.
But simply because, if you have availible a syn. oil made specifically for a rotary,by a reputable company,why wouldnt you run it?

 

i use Amsoil in all of my vehicles, the Rx-7 included. i am so pleased with it that i decided to start selling it.

 

where can you get Idemitsu at? I looked at all the nearest hardware/car stores...

 

I've been running Royal Purple in rotaries for years and love the stuff.

 

Here you go..Idemitsu Sources

"I believe these inferior synthetics will work great in a wankel as they are essentilly dino oils that have been re-engineered."

A synthetic motor oil is by definition petroleum that has been chemically altered. It is my understanding, from a friend who works in the industry, the ALL synthetic motor oils are made from a petroleum base stock, using various kinds of chemical black magic. Of course it is possible that some manufacturer may use castor bean oil or other vegetable based oils in there with the spider legs and bat wings, but I doubt it.

Things like phosphate ester hydraulic fluids are also made from petroleum.

I cannot vouch for the information in the following thread, but it is interesting reading:

The term synthetic is misleading and not terribly accurate. "Synthetic" refers to the process by which the oil is made and not the finished product. "Conventional" oil is distilled from crude oil and filtered. Synthetics are processed through non natural means such as hydrocracking which adds hydrogen, breaks down and recombined certain molecules to get to a more pure state of a finished product. Sure there are some synthetics that are made from different base stocks that weren't petroleum based but they are processed to get the same basic end product. Just remember chemistry class and balancing equations to get a different molecule through some rearranging. This is chemistry equation balancing in the real world. Calling an oil a synthetic is like calling a baby that was born as a result of a mother being artificially inseminated a synthetic human. It doesn't work that way. There is nothing to be scared of when it comes to synthetics except misinformation. When it comes to rotaries and synthetics, misinformation is pretty easy to come across.
