I have a 96 Tbird with a vortech supercharged 4.6L 99 Mustang GT motor, and ported heads, etc, etc.
The car is only in service in the hot summer, so cold weather starts is a non issue.
I am not going to run 5w30 or 5w20 in this motor.
The previous owner went with a 10w30 mobil 1, but I thought that was a little too thin.
I sent a sample to blackstone just now, and I changed the oil to 4 quarts of mobil1 10w30, and 1.5 quarts of mobil1 15w50.
The car is driven hard on the street and is a toy pretty much. It sees pretty much zero time on a track though.
Thanks,
Justin
