Factory Fill oil
Ok, back to the oil discussion for breaking in my rebuilt engine.
When chevy says they factory fill the vette with mobil 1, are they sticking nothing but mobil 1 in there while it's at the factory?
From what you guys have said, I should run dyno oil for 500 miles or so, then I'll be going to Mobil 1. But I'm really curious as to how chevy fills them with Mobil 1 from day 1, yet you guys almost all recommend running dyno oil to seat the rings properly.

Run regular oil for the 1st after 20 minutes and 2nd oil change at 500 miles. Switch to Mobile 1 after 500 miles.

Re: Factory Fill oil (Mez)
I would strongly recommend running conventional oil in a non-OEM motor for at least 5K miles. Monitor oil consumption and switch to synthetic when it seems to stabilize at a reasonably low value like 2K mi/qt or less. If you switch too soon, there is a risk the motor will never break-in and oil consumption could be excessive. There is no drawback to waiting...your motor is not going to wear out in the first 10K miles on dino. Motors built on a GM assembly line are machined with precision tooling that costs many millions. It's been proven they can machine a motor for synthetic factory fill using appropriate tooling and hardware. Even Jasper can not compare.
