When my engine was new, it just had some regular old 10w30 Valvoline in it. I drove it for 500 miles, then took it back to the machine shop that built it. They changed the oil with a new filter, checked out the motor to make sure everything was OK and life was good.
I was pretty easy on my motor for the first 500 miles. The machine shop guys told me to be so i was. Of course after it hit 500 miles and had fresh oil and a filter i just had to open it up to see what it had
