Yes, another oil question. I did a search here and on BTOG. Not too much about Driven oil.
I drive my Corvette on the street 50% of the 50% track use in Time Trials on tracks like NJMS (Thunder) and Summit Point Motorsports Park. The rare is very rarely driven in the winter. The engine was rebuilt in 2016 and the builder recommended 20W-50 oil.
I use VR-1 Racing oil due to the high zinc. But my understanding (which could be faulty) is that racing oil does NOT contain all the normal additives, like detergents and corrosion/rust inhibitors, that would be required by a street driven vehicle.
You're going to get a number of folks who don't see the need to spend so much when Shell Rotella works fine. My '72's engine builder recommended Driven. He used their break-in oil for first runs and dyno testing, then advised that I use the 10w-40 for regular use. It's certainly not inexpensive but I'm also not changing the oil 2-4 times a year. (He also advised Wix oil filters.)
VR1 is good for even a daily driver. From their website:
"Valvoline VR1 Full Synthetic Racing Oil's high zinc formula provides race-level protection for high performance engines on the race track or the highway. Its exclusive chemistry is designed to reduce friction and enhance power. It is among the most popular engine lubricants in all types of racing, including paved and dirt ovals and drag racing. It is formulated for race engines, but compatible with passenger vehicles too."
And conventional:
"Our exclusive high zinc and phosphorus formula is engineered specifically for modern and classic high-performance engines both on and off the track, which includes flat-tappet and performance cam motors."

Thank you! That was useful. I'll have to read up more on that. I did not see that statement on their site. Do they mention the amount, if any, of detergents and corrosion/rust inhibitors?
Gibbs sold GiBBs oil years ago. Hence the name change to Driven. Very good oil and no expense was spared in development when the boys were running Flat Tappets in NASCAR. Carb Defender product is also a go to for storage. Cup cars overnight sitting the garage with ethanol tainted fuels would loose 3HP due to fuel "Decay". Carb Defender developed for this reason. Fuel will maintain octane levels for years.

Thanks. I was wondering about the Gibbs rant above. What did Gibbs do?
I have been using the Driven brand oils for many years and before that when they came with the Gibbs name on them. It is great motor oil albeit a little pricey.
Diesel engine oil like Rotella are no longer made with the right extra zinc we need. They also don't have the right anti-foaming agents we need for our gasoline driven engines. The latest issue of Hot Rod has a nice article explaining why you should no longer trust diesel engine oil in your gas engines.
To figure out which oil is the best for your engine you need to know the bearing clearances from inside your engine. My engine was built with tight tolerances and prefers a 0-15 from Driven.
Rings and bearings. Not arguing the zinc part. It's the "boutique" brands of oil. Hell, you could throw that Supertech oil in there that Walmart sells, add some ZDDP additive along with it and be good to go. With that said, I use Dale Junior approved Valvoline VR-1 non synthetic in the Vette, Motorcraft oll and filters in my Ford Ranger. Now I need to see who "Rich Children Racing" is partnered with and go back to eating M&M's at the movies.

What I find interesting is that I sent TWO emails to Valvoline through their wedsite asking if their VR-1 oil has normal additives, like detergents and corrosion/rust inhibitors, that would be required by a street driven vehicle.
They never answered.
