Finally got the milky white substance in oil that I've been hearing from so many of you in the Northern States.

Freaked me out as I haven't seen this before. I checked the TSB and looks like it's normal:
MILKY SUBSTANCE ON OIL LEVEL GAUGE (DIPSTICK)

"On some vehicles, during engine oil level check, the customer may find a milky substance sticking to the oil level gauge. When you encounter a customer complaint for this concern, explain to the customer that this milky substance does not affect engine performance or any other functions of the vehicle.
During cold weather, moisture contained in blow-by gases (exhaust, oil, fuel, water vapor) is cooled by the inter-mediate housing wall and condenses due to difference in temperature. The moisture reacts chemically with the
engine oil in the intermediate housing and the milky substance appears. The substance eventually dissipates when engine reaches full operating temperature.
This milky substance does not affect the quality of the engine oil and engine performance is not affected. Mazda Motor Corporation has verified the amount of moisture in the oil is within the acceptable standard for motor oils commonly found in the market. Verify the coolant reservoir is full and there is no sign of engine coolant leakage."

Freaked me out at first, since being an 8 owner for six years, never saw this before and I check my oil regularly. Anyone else from the South experience this for the first time? And is it worth bothering local dealership about the 'cosmetic' TSB?

 

It is supposed to taste like a milkshake. Try it.

 

It's normal, don't worry about it.

Best thing to do is not drive the car short distances.

 

You're in FL correct?

I guess you guys have never been in such cold weather before. Those white stuff is just water.

no biggie.

 

saw it once. everything will be fine. relax.

 

Mine tastes like chocolate milkshake))

 

I heard if you stuff a banana down the oil filler that you can get a chocholate flavoured banana smoothie ...

 

 

Jizz ... in my... oil

 

Tmi....

 

Too much information, not enough pictures.

GET ON IT, Sparticus!

 

Thank goodness for this post; sets my mind at ease. We've had a pretty good cold blast here in Houston and now the white stuff on my dipstick (that's what she said).

Good info, thanks!

 

Why does she have a dipstick?

 

Just had my first encounter with this too and I was freaking out... lol, glad its normal thanks for the thread!
