I am approaching 400 miles, I called my dealer and ask if I should change the break-in oil at 500 miles to Synthetic. He said I should wait until 3K.

Subdriver is a sponsor of this forum and an Amsoil distributer. He has an intro stuck in the garage section. He may be the best qualified to answer your question.

You don't want to use a synthetic until about 5,000 miles so that the piston rings will seat properly.

You don't want to use a synthetic until about 5,000 miles so that the piston rings will seat properly.

Is that direction from GM, or personal opinion? My 05 came with Mobil 1 synthetic in it.

When I was getting mine a couple of months ago I had them change it to Mobil1 with no miles on the clock. No problems here.

I believe the LS2's all come with Mobil 1 already in the motor. Since the motor is almost the exact same as the one in the Corvette, and the Corvette is broken in with Mobil 1, I don't think you can go wrong either way.

I know on the '04 cars, Mobil 1 did NOT come in the motors, which kind of confuses me. Oh well, I switched to Mobil 1 last week, with 1300 miles on the odo.

The dealer said they changed mine to Mobil 1 while they were prepping it for me to pick up, 50 miles on odometer, however when I checked the oil it was very red in color, may be GM synthetic ??
