Mobil 1 synthetic vrs. dino motor oil
First this is not a which is better thread.
I am trying to diagnose a head gasket leak. I followed the collective advice of forum members and used some Mobil 1 full synthetic. I am getting oil in the intake from somewhere I think. I am going to work on it today so need some advice. I have read about every thread on head gasket failure but did not come across anything about synthetic oil.
When synthetic is burned in the motor will it produce the same white smoke that dino oil does? I have used 2 stroke synthetic that does not smoke.
When water (coolant) is present in the oil will it look the same as with dino?
Is it normal for the oil pressure gauge to sit on high (3) until the car warms up to normal temps then drop back to 2?
