I have an Rx-8 in Pa. It is currently very cold (single digits). I was check my oil and found the dip stick covered with brownish/white foam. I called the dealer and he says don't worry about it? The car has 6K miles. The dealer has changed the oil once.



Your thoughts?

Check your coolant levels. Frothy oil is a big indicator of a blown head gasket in piston engine and an indication of water seal failure in a rotary. Ever consider changing the oil yourself to see what's in there? It probably should have been changed a few times by now. (500/1000/3000/6000)

yeah that sounds like coolant, good thing you have a warranty!

or that head gasket thing........JK

Actually Mazda Service manual puts their oil changes at 5k now.....



And yea that don't sound good at all.

I did not know that. Does that apply to new motors as well?
