Redline synthetic motor oil

What kind of oil do you put in a motor that’s worth more than some Miatas? Full synthetic. It’s thinner at low temperatures and holds viscosity better at higher temperatures than standard oils. Redline is what we use in every car we drive, from full-bore competition cars to fun daily drivers to hard working tow vehicles.
