Engine Size: 3.0L
Issue/Question: I just bought this car and was informed that I have synthetic oil in the car. I am not sure what brand is in the car, but was told to use Amsoil. If I decide to go with Amsoil, will it affect the engine when mixed with the oil in the engine now? Also, how long between oil changes? Why use Amsoil than some other synthetic oil. I hope to hear back from you soon. Thank you again.
I recommend you go to amsoil.com and do some research on it for yourself, Amsoil was the first synthetic oil manufactured for internal combustion engines in the US. It uses twice the amount of POA bases in their oils compared to any other PAO oil. Note: Mobil is a PAO, Castrol, Valvoline, Pennsoil, and the rest are all hydrocracked petroleum oils with synthetic written on the bottles! They are not a real synthetic oil. Good luck.
