Motor Oils

[Phokaioglaukos]

Thanks, Brian, I think. Oils can be a religious matter. No easy answers here, and we won't know for the newer, water-cooled cars what we should have done until it's too late! If I had an air-cooled car I'd stick with an oil with additive specs that were current at the time the car was built, but on a synthetic base, if possible. For my car I'm sticking with Porsche's recommendations, and worrying.
