I took my rx8 to get its oil changed. After it was done, the car idled very rough and would not stay on, and the check engine light was flashing. I brought the car back to the oil change place thinking mabye they put in too much oil. They drained it and chaned the filter again. This seemed to make matters worse and the car struggled to start and a white colored smoke started coming from under the hood. I got the to the dealership, barley, and it killed with lots of white smoke. There is a chance they may have put in 6 qts instead of 3.7/4....hmmmmmmmm

 

hmmmmmm, i dont think thats possible...that COULDNT be caused by to much oil...

might wanna check your plugs, and coils

 

its in the dealerships hands now....it was running fine prior to this nightmare. I was getting the oil changed because I am getting ready to drive it across country. Now i am stuck

 

if they put too mcuh oil in and it somhow filled the rotor houseing it def wold have ahard time running but if they but the correct amount back in it might b coils/plugs something....

one more reason to do your own oil change.

install fumoto valve, twist and drain. No need for any tools!

 

I've seen too much oil gum-up the SSV valve, but I doubt the valve would stick right away.
My first thought would be the MAF sensor getting contaminated due to excessive oil running up the breather hose and into your intake.
I would clean the MAF with some contact cleaner.

Also, you can remove the accordion tube before the throttle body and see/feel for any oil residue.
That will tell you for sure if this was caused by excessive oil.

 

yeah the MAF is very possible to get oilon it if you overfill it even by about a qt it will get oil in the intake piping and hence getting it on the MAF

 

Oh boy.......what a mess. If they really, really put in 6, then yeah........it's probably all over the MAF, the intake tube, the air filter, etc.

As someone just said..............all you folks that don't know how to at least change your oil, or think you're too busy................here ya go! It's only a matter of time!

 

^exactly if you know how to do it it should not take more than 20 minutes and that's with using the stock scissor jack that comes withthe car and clean up

 

The "etc" being the throttle body, intake manifold extension, SSV......
I would definitely check for oil residue before and after the throttle body.
It'll be easy to clean it now than later.

 

Yep......it could be nasty.

 

I have a very hard time taking my car to places to have someone else change the oil I watch those people like a hawk im very protective of my women .

 

Oh..........to the OP, we all do hope you get your car worked out and the issue taken care of.

BTW..........did I mention I have an oil catch can for sale?

Shameless plug, but it might have helped in this instance.

 

thats why i always have the mazda dealer do everything, incase they **** up it'll be covered

 

I'm interested in the white smoke and the flashing CEL (miss)...
Perhaps they spilled oil the first time on your coils or something like that but didn't tell you about it. Overfilling wouldn't lead to a bunch of smoke... even then, burning oil doesn't cause white smoke.
Plus if it smoked all the way to the dealer and was still white smoke and then it died in the dealer parking lot, I don't know if it would be caused by too much oil. Or I'm missing something obvious.

I'm very interested to see what the dealer comes up with.

 

huh?

beers

 

ok,

why. the cel was flashing at idle??? doubtful.. was it flashing at full throttle?

white colored smoke is a coolant leak..
the dealership. barley?

depending on the oil drain, i put in 6qts. but how would you know what they did?

this post is a fishing trip.. let us know if you have a clue.

beer

 

Yepper, I believe the oil change had nothing to do with it.

Kep us posted.

 

Sounds like they looked up the system capacity, and then put that much in.

With that much excess, could oil be seeping in past the side seals?

Oh wait, you said white smoke from under the HOOD.... not the exhaust?

 

Well he states; "oil change place" then "I got the to the dealership" so I guess 2 places had there hands on your car.
This all sounds crazy

 

nevermind swoope i was thinking normal piston enginehow the oil pan/oil has access to the pistons/cylinders and could get in the firing chamber...

BRAIN FART!!!!

 

oh god, what a nightmare...

 

what me having a Brain Fart?? lol j/k

 

A similar thing happened to me. I brought the car into the stealer for an oil change. After the oil change, I drove home and checked the oil level (something I do regularly). The oil level was so high, I could not see where it ended on the dipstick. Even after wiping it and putting it back in/out again, the whole dip stick was covered in oil.

I didn't drive the car the next day, but drove it on the following day. It was fine for a while and then it started misfiring and trying to stall. The CEL light was flashing. I pulled over and looked under the hood, checking the oil level again, and it was still covering the entire dipstick. Now the stealer tells me I need a new engine. Could overfilling the oil cause this???
