What is the best synthetic oil?

If you truely want the best of the best oil, IMHO get Motul 300v, hands down the best...and its an ester oil as nissan recommends. As a matter of fact, its a double ester based oil...top of the line stuff at a premium tho...

Check out the "oil nerds thread" and also do some research on Bobistheoilguy.

But the short answer is, it's a hotly debated topic.

Amsoil

I like Bertolli. It lowers the engine's cholesterol.

I've found that a 1:1 mixture of Castrol GTX and toilet water makes the car run much smoother and quieter. Nastier the toilet water, better she runs. My Z is a dirty girl.

I'm running Amsoil's Signature Series 0W-30, but I'm considering moving to a 5W-40.

I am very happy with the 0w-30. I am switching between the 0w30 and the 5w30 right now but i am so happy with the gas mileage on the 0w30 im gonna stick with it year around

All of these are good, but I have seen enough UOAs that prove Royal Purple causes more wear on cars and doesn't like extended intervals.

Best to worse

Redline
Amsoil
Penzoil Ultra
Penzoil Plat
Castrol German
Mobil 1
Motul
Royal Purple
Castrol Syntec
