If it can be seen it will be on the dipstick when you first pull it out. Also check in the rad for traces of oil floating.
A bad head gasket is the most common cause of antifreeze mixing in the oil. The antifreeze will dilute the oil and it will eventually cause your engine to seize up.
Could be oil mixing with antifreeze indicating a bad head gasket Are you losing motor oil?
You may have a head gasket problem or a cracked head, engine oil is mixing with the antifreeze.
Look at the oil on the dipstick. If you have antifreeze leaking into the crankcase the oil will be milky.
if he means antifreeze is getting in the oil you could have a bad head gasket or even a cracked block not good either way
The antifreeze/water mixture is too weak for the conditions or you have engine oil or trans fluid mixing with it
If there is motor oil in the antifreeze reservoir there is a good chance there is also antifreeze in the motor oil. This condition is probably the result of a bad head gasket or a cracked head. Antifreeze mixing with motor oil is a recipe for disaster for the engine. Have a trusted mechanic diagnose the situation soon as possible to hopefully avoid even more costly repairs.
Odds are you have blown a head gasket and the antifreeze and oil flow share the same gasket. As the gasket wears, the antifreeze mixes into the oil and vice versa! I suggest replacing your current antifreeze and do a full flush. Test it for a few days and test if you have oil again. A tell tell sign of a blown head gasket is black smoke (burning oil) or white smoke (burning antifreeze ) coming out the exhaust.
I believe it turns milky looking or your oil level keeps going up
well one way to tell is if the oil is a milky color..... that means the oil is mixed with your antifreeze
A 50% water 50% antifreeze is recommended.
No the engine is not ruined. It needs a new head gasket and an oil change after the gasket been changed.
