Hey, yeah had the same issue with mine. Had been sitting on the car lot for 3 months after being in transit from japan.

The primary reason that the foamy substance occurs is that all mineral based oil has water content. Over time when the engine is not being used (read regularly) it separates out, and begins to evaporate upwards. Hence the larger amount found around the dipstick bung.

Regarding oil levels. The best time to check levels are at cold. Try not to overfill it as it will seep down the rubber accordion (intake). Not detrimental as you can just wipe excess out.

Hope this helps.
PS, all of us had to learn somewhere. Good to see you're making use of the forum.

 

oh my god ... mineral oil has water content, and it separates when its not being used ! Thats a brilliant idea !

WOW ... this forum is really ... loaded with ... smart people !

 

your lack of common sense amused me.

I do know that a lot of kids in school are looking for direct answers to all their test/homework. Why don't u do everybody there a favor and give it to them? moron.

You don't research, you don't study, you don't learn. Simple.

but I guess I just waste my time again right? cuz morons like you never understands the learning process. oh well. me out ~ (n free post count!)

 

How am I supposed to search for something I don't know about? I'm a llittle rusty on practical divining rod usage...

 

why don't you try to figure that out yourself? threads about that "issue" is all over the place, if you actually read them you already got the answer.

we're not ur mom, not our responsibility to spoon feed u.

 

But I love not having to do anything for myself! It's much easier to just ask and make everybody do the work for me.

'Murica!

 

you're right, looks like i guessed my way into the university of iowa's medical field.

so im sorry i dont have time to look up pitty info about oil on a car forum when im writing a 35 page paper on stem cells. and meiosis vs. mitosis.

so if you want to sit around on an online forum and boss people around and act like the internet police then go right ahead. but its very ignorant of you to call people morons before you even know who you're talking to...

 

hah this did not help me at all...
9k good luck on your issue, and thanks nycgps for reminding us why no one wants to visit New York

 

oooo omg stem cells impressed me you're so damn smart but you still FAILED AT SEARCH/Use Google?

just because you get into medical field does not mean you're smart. because given enough time and effort anybody can get into medical field.

hmm if your'e so smart you would've got the answer on your own? ohhh I know why, I bet ya that they never taught u how to find answers on google? oh man I feel 100+ to my IQ now.

gotta love those "morons" who think people on forums have to spend 8+ hrs a day to read/reply post ... and they came to these "no life losers" for tips ... ROFL.

 

you're right ... *sigh*

 

yeah that means practically nothing. Had a Doctor of physics in here a few years ago that was a complete moron. you could tell he was a complete moron by the way he couldn't see the answer he was looking for was in another active thread that was right next to his- even when he was given a link to the thread.

turned out he was a bigoted moron with a serious Napoleon complex.

you education level and IQ don't make you wise or give you common sense.

edit: btw Im currently reading through the research being done at University of Missouri Columbia about RNA folding and mis-folding and its role in disease creation. you should check it out http://vfold.missouri.edu/chen-lab02.html

 

zoom is wise in the ways of internetz

 

Read the Stickies? They are at the top of the forum and one of them is about foamy oil.

https://www.rx8club.com/series-i-trouble-shooting-95/

It's not always about searching using the search function. Often its just reading the stickies and/or other current threads...

 

i know a phd in physics who can't figure out how to dribble a basketball, who is smarter?

 

Yeah... I read the premix thread... 10 pages of troubleshooting (oddly enough, not the stickies on there... Haha), just got done with the tranny issues. All in all, I've read a ton of stuff on here. Considering that I don't even have an 8 yet, I'd say I'm doing just fine.

Let me tell you though, I won't be getting an 04!

 

Thats the way to do it! Know whats going on with the car before you get it so that you don't have to freak out and cram in a lot of info right when you do.....

And not all '04s are full of problems. I love mine. But yeah if you want better odds of not having them pop up, get a later year. And take good care of it! (which it sounds like you will)

 

Your Simota intake has show us how smart you are.

 

no the one that is titled Strange "gunk" in Oil or on Dipstick - Info/Questions is the one that pertains to this thread. which means you didnt even read the titles of the threads that the link took you to. because the pre-mix thread isnt in the list in the link

 

Stop hitting yourself in the face dude lol its not that big of a deal

 

9Kbeep im glad you brought this topic up, The same problem happened with me. This thread helped me i want to thank everyone as well for info. Some topics do need to be brought up again

 

brought up again?

its the second thread from the top! https://www.rx8club.com/forumdisplay.php?f=95

 

*facepalm x 100000000*

The oil temp in the RX8 never gets high enough in cool weather unless you're really flogging the engine.
Here's a bit of data. (BTW, The oil temp gauge reads temperature at the oil filter which is after the oil coolers and just before re-entering the engine)
In 40F weather my oil stays at 160F on the highway at 75MPH no matter how long I drive it.
cooler temp = cooler oil.
To achieve 185F oil temp I had to drive hard, maintain high RPM and stay below 4th gear to hit 185F. This is a bit hard on the wallet.
People will tell you that oil temp follows coolant temp but this is applies more to the top end of the temp scale. In winter the oil can be much cooler than the coolant temp.
The cool oil temps are responsible for normal condensation not being 'burned off' and the condensation causes the foam.
My suggestion is to get an oil temp gauge and then partially block the oil coolers until you can maintain minimum 180F oil temps.

 

Your english show us how smart you are. Not to mention the 14,000+ posts of captioned pictures and useless information, oh and the face palms get me everytime
Ps: My simota makes my car go vroom
