I recently did an oil change on my car, obviously a V8. I put brand new Penzoil Platinum Full Synthetic Oil. I also added Sea Foam to help clean my engine out. A friend of mine told me I should put Liqui Moly Ceratec. I was wondering if putting the LMC would be an issue with the Sea Foam already in my crank case. Second part to this question is, does LMC really help, what are the good and bad things about adding this chemical to my oil. Any advice would be great, I really love my car and I would hate to do anything to mess up the engine.
