The reasons synthetic oils are better

[karnac05]

Hi,

\'Castrol\' is a good oil for a RX7?

Thanks

[oilman]

The Edge engine is is not ideal, however the gear, diff and brake fluids from Castrol are all ok.

Cheers

HI,

A mineral oil 10w-40 is ideal for a FD3S or a 15w-40??

Thanks

Hi everyone!!!:Thumbs-up
 
I just wanted some advice about a new oil I just discovered... It\'s a 100% Synthetic White Oil called Spheretech!!!
 
The specialists (Oilman... Clive... etc...) will probably know a few things about this Oil... It only comes in 0W40 and I wanted to have Objective thoughts and advices about this oil... Even though I\'m convinced the Motul 300V is one of the best oil to put in my RX7, I would like to know a bit more about this white oil!!!
 
Thanks a lot, guys!!!:wiggle

Trouble is as i see it is the rotary needs to be able to burn the oil cleanly within the engine, the ceramic particles in this arn\'t going to burn so it follows they will leave a deposit within the engine, which may inturn lead to stuck seals. Unless of course your running premix.

Synthetic oils burn far cleaner than mineral oils and in fact leave far less deposits and carbon, just ask someone who uses synthetics like Silkolene Pro S or 300V just how clean their engine is when stripped. It\'s only bog standard cheap mineral oils that leave nasty deposits.

If your RX7 is modded I would recommend nothing else, if it\'s a stock NA then there is no harm with a basic oil but at least use a semi-synthetic as it will be mineral oil based, they all are!

Out of interest, What do you make of the white oil, Simon?

Looks interesting but not worth the money when you can buy the likes of Silkolene Pro, Motul 300V, Redline or Castrol Edge for less.

Gimmick really, how about red oil, Pro S 5w-40 or Motul 300V 5w-30 smells of bananas, need I go on?

I do like the Motul 300v\'s banana smell!!

what about Valvoline Racing 20W50 my mate uses gallons of the stuff in his Pinto powered rally car (they apparently used to run it in top fuel engines)  so it\'s been what I\'ve run mine on as it is convenient for me and "modern" oils are harder to find in the thick grades.

Just saw this comment over on Ausrotary from Rice Racing:

I just tore down a 100 000km REW motor that has a perfect tune up in it, always ran synthetic oils (factory OMP) and ran stihl 200:1 premix, the wear is very low and the carbon build up is less than in engines that have done 2000km. There is very very little carbon deposits in the engine be it rotor faces, exhaust ports or secondary intake runners.

Not worth the money...? Ok it\'s a bit more expensive... But technically would it be OK to put in our RX7 and the quality of this white oil seems good doesn\'t it... Surely you must have heard a few things about this oil...
 
Is 0W40 a proble for the engine? Isn\'t it too fluid or is "0" at low temperature OK?
 
I know the other oils are great, I just want to know a bit more about this white oil and see ojective comments about it... Are it\'s chemical properties as good as Motul 300V or Silkolene?:cool  
 
Thanks.

Reading this thread is great news for me - until I read it, I thought I\'d have to have two stocks of oil, one for my DC5 and one for the FD. Now I can use the same Silkolene Pro S 5w40 in both! (Can\'t I Simon!? :3Confused Just to check! )

[Well, I can use the same in both once I do an oil change on the FD anyway...]

[oilman]

I would use it without hesitation

Cheers
Simon

[oilman]

The Pro S will be fine in the FD.

Cheers

Guy.
