I know everyone says to put 10-20K on the engine before switching over to syn but what is the best Dyno oil on the market? And are most of you guys using the OEM oil filter or something lke the Mobil 1 oil filter? Thanks.

 

For dyno oil, I prefer Castrol GTX. IMO, one of the best dyno oils.

 

What's "Dyno" oil?

 

from dinosaurs, as opposed to synthetics

 

I think he means "dino" oil "dyno" is a totally different thing. Best dino oils around are Castrol GTX, Chevron Supreme/Havoline, Motorcraft, and Pennzoil.
