I have been using various Valvoline synthetic oils 10+ years in multiple stationary engines, tractors, diesel and petrol engines. No sludge, no varnish inside the engines, and never worn an engine out.
Pros: no sludge, no varnish

I use Valvoline restore and protect. It fixed the tick after a few oil changes
Pros: fixed the tick
5W30 Valvoline Restore and Protect is good
Pros: good restore and protect
Vehicle:
Ford Mustang
Valvoline Restore & Protect is reportedly great.
Pros: reportedly great
I run Valvoline restore & protect because 2x 5 qt jugs fits my 4 qt Prius and 6 qt Maverick perfectly and I run it on the Prius which has stopped oil burning from the low tension rings.
Pros: stopped oil burning
Vehicle:
Toyota Prius
Valvoline has their hypoids available in handy-dandy squeeze to dispense bags that let you fill the case up without spilling anything.
Pros: handy squeeze to dispense bags
Cons: oil is oil
Both of my Guzzis ran better on Valvoline. This is if you’re in USA
Pros: ran better
I'm using Valvoline 0W-20 Restore and Protect, changing every 4,000 miles. '23 OBW, 56,000 miles. FYI, I did an oil analysis at my last oil change. Wear numbers were excellent, less than 1.5 ppm/1,000 miles. 3 iron, 2 aluminum, 1 copper over 4,128 miles. Fuel dilution was HIGH though, at 4.3%. They expect 1.5- 1.8% for direct injection turbos. According to the Motor Oil Geek, less than 5ppm/1,000 miles is considered good. I do a fair number of short trips, but also some longer runs. I'm going to go to max of 4,000 miles due to the gas dilution.
Pros: excellent wear numbers
Cons: high fuel dilution
Vehicle:
Subaru Outback
Mileage: 56000 km
Nissans are hard to read too. Valvoline always shows me the stick and I can barely see the proper fill level. Car is usually fine.
Cons: hard to read
I do believe that Valvoline R and R can cause oil leaks. I have noticed that in a couple of cars.
Cons: can cause oil leaks
