Read all of my post above, especially the first line

I states "From Mazdatrix" - that entire post is from the mazdatrix website...

http://www.mazdatrix.com/FAQ/SYNTHETC.HTM

As for my opinion....

I do use sythentic in my 1993 Rx7 since it's a high HP car and sees extremes that the average rotary does not see.

Would I use synthetic oil in my Rx8? - nope, for the same reasons Mazdatrix quoted.

so you did not do any reading and just quote mazdatrix.. (great people and great service btw!)

that blurb that you quoted was the old stuff from the old days with the mobil 1 and rubber seal problems... and many here with over 50 k miles running syn.....

btw.. how do you think syn will work for the extremes but not the average???

It works in extremes for me since I do not use an MOP, if I did, I would not use synthetic.

Can you please let me know which forum members have been running synthetic oil for 50K miles, this one I am curious about...

About the month late, I was too busy reading silly threads from guys who forget to loosen lug nuts when they want to take their wheels off An example here...

https://www.rx8club.com/showthread.p...9&page=1&pp=15

I would definitely take his advice seriously, a lot of hard core rotary experience on that post!



Anthony

 

wow,

i was honest and forgot to loosen before i jacked.... but the point of the thread that you missed is?????

you can get an extra two qts of oil out of the motor if done right..... silly me. forget the lugnuts, but got 2 qts more of the dirty oil out...

now be honest, i was i made a stupid mistake and forgot to loosen lugnuts...

you just got your rx8 and you know everything about syn oil.... and the rx8 motor....

guess you win..

really take the time to read the links i have given you.. lots if info on them... btw. please change your oil like everyone else and only get out 4 qts...

beers

 

and you know what... i think it would be interesting for you to start a poll of members using syn oil....and how many mile on the car...

go for it..

beers

 

No need for me to start a poll since you already know who they are right? As you stated "and many here with over 50 k miles running synthetic....."

I asked you to please let me know who these many are. Your next post should answer the question. I'll make it clear for you again.

As you stated before, please tell us who the "many" are on this forum running synthetic oil for over 50K miles.

Thanks,

Anthony

 

I'd just keep the reciept... if anything ever goes wrong that could possibly be blamed on the oil, then that could be handy

 

I've run synthetic oil for about the past 7 or 8 years on 3 different RX-7's. I will never use anything but synthetic oil.

 

working on it.

Anthony dont even try you're going to lose badly.

If you're here long enough, you would know tons of people here use synthetic without any problems , some even went past the 100K miles mark already.

I've been using NOTHING but synthetic oil in my 8 ... yeah did my first oil change at 1K miles and now 19000 miles still running strong ...

I find it funny that people still afraid of something that happened 20 something years ago. Oh no Synthetic oil bad bad for rotary ... oh wait why did they have problems ? ... carbon ? it came from the Gas we put in ... not engine oil .... Rubber O-ring seals ? ..... oh great I thought they changed that 20 something years ago ....

 

I think I would be pissed. people just never listen to their customer(S).

but hell, I wonder where in the manual thats against synthetics.

 

Nowhere. At least not in the electronic version of the '06 owner's manual.

Something I never noticed before is that the manual doesn't even specify API Service SL. It just specifies that the oil needs to have the API star, be ILSAC approved, and be 5w20.

I know other stuff (like the current version of the orientation video) says SL and recommends against synthetics, but this version of the owner's manual does not.

this is the same stuff that comes up every couple of months... another thread is kinda doing the same thing..

they have a partial pic of a bulliten for europe saying no syn...

i can believe that the little booklet has not shown up yet... they always find that one..

funny it is always new yorkers that start this and one always claims to work for or has a freind that works for a dealership..

just more fun.

The whole idea of using synthetic is appealing to me, I have a case of RP waiting in my garage but I have to admit there is something which is nagging at me. I have never seen any engines torn down after using RP for an extended period. Every thing supporting this is speculation or hearsay.

Some people here have used RP on previous rotary engines with out issue and reason that the RENESIS can also use it as well. The only problem with this logic is that the side exhaust ports of the RENESIS is more prone to carbon build up. This was why the side ports were not used in earlier rotary engines. Supposedly the new computer management system for oil injection can meter it to the point that this issue is resolved. Now there are reports of some synthetics clogging these very ports.

I have to say that opinions are one thing but I would like to see a couple of these engines torn down after 30K of using RP to be sure.

 

it's actually not the car being able to handle synthetics now, its the oil technology improving since synthetics of the 80s and 90s.
