If you keep it clean with appropriate change intervals and use proper weight with any API certified oil, I have to think you are going to be alright for a road car.

Mostly because almost everyone is using a decent oil.
The problems beagan back in the early 2000s when there was a switch in some oils to less than a 1000ppm ZDDP, it's now common is some oils to have 800ppm or less. Thes oils don't provide proper wear characteristics on the cam lobes. I know one fellow that trashed his 964 after just a year or so of using such oil.
Use the right weight and right ZDDP content and the car will be happy, there are several very good oils out there and also some marginal ones. Just avoid the sub 1000 ppm ZDDP oils by doing your due diligence
