STG said:Mobil is a group IV PAO FULL, REAL, TRUE, etc. synthetic. Call them up and ask to speak to one of their engineers.
As far as Amsoil is concerned, I refuse to put any oil not certified by API in any of my vehicles. If you read Amsoil's marketing hype, you will find that theit oils are "made" to or "meet" API specifications. They do not have the API seal on the bottle. Amsoil claims they don't want to pay for API testing.
The fact is Mobil 1 has been around for years, is a true PAO full synthetic, is made by a reputable refiner, and is factory fill in many of the world's exotic cars.
Problem here is your trust the API to much. I have used Amsoil for years and done very well. I dislike the marketing but they sell oil. Api for me, means nothing and never will. You can make an oil meet APi specs then fall flat on there face.
Based on some gas testing Mobil is not a POA as noted. I have called there CS people and they are rude and do not understand oils. Anyone can read "typical" PR stuff on a screen to anyone on the phone.
Mobil is good but they are ridding Amsoil since the 1970's. How many times does mobil need to try the extended drains. If you have used this oil, along with others and it provides the best UOA (in all areas) then you should use it.
