Hi, I am using Mobil One synthetic oil for previous oil changes on my G and would like to change to the Castrol syntetic. In Castrol which one is really best synthetic oil? Syntec, GTX or EDGE? It is very confusing... Also any experience using one vs another? Thanks!

 

Just stick with mobile1 5w30. Doesnt it recommend that in the manual or does it recommend easter oil or w/e its called.

 

The best thing to do is delete this thread and go read one of the thousands of oil threads in the oil section.

IBTL!

 

Castrol Edge 5w30 is what I use in our G37s. Mobil1 has changed their formula over the last 2 years to want to use it any longer as its not as good as it used to be. I use 5w30 Edge in all 6 of our cars including my 800 rwhp blown Z06.

 

I would like to see a picture of that monster!

 

Sell the G and supercharge the corvette. You will thank me later!

 

The Vette is supercharged if that comment was to me. The G is my wife's driver so I don't mess with it cept for putting gas in it for her sometimes.

 

Dyno numbers>?

 

Ill PM you as I dont wanna hijack this thread on a non G37 car...
