| I guess I'll weigh in on this. For those who do not know, I am an ASE master Certified Automotive Tech.
#1 Get under the car and see if you have any leaks, If it is dry then move on, Pay attention to the pressure sensor. If you see oil on the connector change the sensor. If you want to check the pressure use a mechanical gauge in the oil sensor hole. pressure at idle should be no less than 7 psi.
#2 most modern vehicles use low tension rings, that means better fuel milage, but increced oil consumption. manufacturs spec say that up to 2 quarts between oil changes is normal.
#3 If any leaks under the vehicle like fnt and rear main seals could be caused by sticking PCV valve, don't try to clean replace it.
#4 If gaskets are leaking replace them, don't tighten the bolts.
#5 The only additive I would recamend is Lucus products. Seafoam to me is equal to the multitude of snake oil products to fix problems that need to be mechanical repaired.
Just my 2 cents
