ive read through most of the forums...som say synthetic better...som use the reg stuff....n som use premix.
first wat is premix? n second...i still dono wat kinda oil i should use... anyone wanna give suggestion...why use synthetic? (somthing about carbon build up=bad) but som people say lubricate better....wat oil should i use???

 

DON'T use synthetic and DON'T type slang unless you're an Icy Hot Stunta...

 

Maybe when I can understand his post, I'll reply.

And only the uninformed and naive say you can't use any synthetic in a rotary.

 

ok...many people say to use synthetic oil...but many people also say its bad for the car...because of carbon build up......what should i use????


n what is premix???

 

Use the search button for pre-mix. This topic has been talked about many times. NEVER use synthetic in your car unless you pre-mix. Our engines burn some oil in the chamber naturaly, when synthetic burns it burns very dirty.

 

you can use synthetic oil that is ashless it doesn't break down...isn't purple royal synthetic?

 

cmon guys.. don't confuse him.. all he needs to know is not to use synthetic so he won't have to worry about premix...

j/k

 

That is a purely incorrect answer.

 

Premix it 2/4 stroke oil added to the gas..

People say don't use synthics because it doesn't burn cleanly..

Fossil based burns cleaner.. so people say use that..

Many Synthetics now don't burn unclean... but it will just be a waste of money.. unless on a turbo car.

 

i know.. to add to the confusion

 

i have a 88 turbo II so your saying synthetic good for it??

Here is my contribute.

Synthetic oil; You really don't need it. Just make sure you do regular oil changes ever 3,000 miles and your fine.Sythetic oils can break down and leave resdue...but carbon build up does not really come from oil...it actually comes from un burnt gasoline. Pre-mix is not the greatest thing to do to a car. Many Rx-7 owners do it. I guess when people use fuel cut off the chamber is completely dry. Pre-mix is good for turbocharged rotary cars since the at high rpm oil stops being dripped into the chamber.

 

damned links!!!, ok just search for pre-mix all questions will be answered.

 

i was just at that 2nd thread...so its basically putting oil into the gas tank?!?!?!?!

 

No it is clueless and incorrect.

As posted 100 times (and if homey_v had searched) he would have found that better quality synthetics are as good if not better than conventional oils.

He would have also found that poor quality synthetics are much worse than many conventional oils.

But oils like Redline, Neo, Royal Purple, Amsoil and mobil1 all burn cleaner, leave less residue and produce more HP than useing a conventional oil.

But crappy synthetics like Castrol Syntec, Valvoline, Havoline, etc. are much worse than conventional oils as far as leaving deposits.

But every synthetic made, burns at considerably lower temps and under what the rotary engines combustion temp is.

Again the only reason that the owners manuals say not to use synthetics, is because at the time of publication there were no decent synthetics, and Mazda could really say "don't use Valvoline Synthetic, but its okay to use Royal Purple".

 

well yeah... Think about your lawn mower or chain saw...they use 2 stroke oil.

 

yae ive searched...half n half say.....synthetic better...they other half say conventional is better
and lotsa others say premix

 

castrol is bad? at this pole...the castrol got the most votes

 

well you asked back on the 23rd almost the same question and it was answered then.

 

short answer: yes
long answer: not just putting any oil the gas tank. read through the whole thread to understand it.

 

lol answered? i had no clue...what they were saying

 

ok reading

 

Please read what has been written, I am sorry it is in english.

Castrol Syntec has shown in tests to have a higher ash content and other issues than most oils.

But the conventional Castrol GTX is one of the best oils for any amount of money that can be used.

Two different oils, made at two different factories.

 

For Horney

Don't use Synthetic: because you are not knowledgeable yet and understand why or why its not good.

Pre-Mix: If your N/A you really don't need it. The oil metering pump does its job well.

Regular oil: Just use that.....If it works fine...why change? Just change it ever 3000 miles.

Sythetic was an oil that was design to not break down. Its don't ment to be burnt. However, oil is going to get burnt and that was the down side. After a couple years synthetic was design to burn clear with less ash content. Since are engine is design to burn oil the clash among convential oil/pre-mix/synthetic has been an on going battle.
