Is this a race car or street car?
If it's a street car with a roller cam, I would run the Gibbs
oil through the break-in procedure. After that, I would switch to an
oil of your choice....I use Shell Rotella in all of my roller cam engines.
If it's a race car and you're looking for a few extra ponies, then I would continue to use the Gibbs
oil.
