At the site of Nova, under specs it is recommended C6TF.
The engine was delivered,brand new, included a C7TF.
After some reading around the net i found similar engines running a C8TGH.
I have also in my bag one C6TGF.
After all that i am confused about my choises.
Should i go for the break in with C6TGF or C7TF?
After at that i will go on by using C8TGH?
The temperature here in Greece is about 5-35 Celsius
