I'm going full synthetic of course.
I just need to know what weight to use.
Normally the G35s take 5w 30.
I was told 10w 30 Synthetic for FI engines.
Just wanted to reconfirm because my oil change is due today.

By the way, I'm from Boston, MA. (I guess temperature has some things to do with what weight oil to use as well...)

 

I would recommend 10w30 for the warmer months and go back to 5w30 when it stays cold.

 

Thanks man.

 

wow, both of your SC are putting out about the same power!

 

yeh but i'm running 7psi and he's running under 6....dang.
8 )

 

I would say go to 10w but it never gets that hot in Boston. Summer time Ill be switchin to50 weight since Ill be tracking.

Hey Randy how are you?

Great numbers guys I got a procharger with 7.5psi doin 382whp/ 332wtq.

 

I use 10w30, winters here are never that cold though

 

AJ, I'm great!

 

it's all in the tuning...
