I use the Mobil 1 Racing 4T 10W-40 which is synthetic *and* meets JASO, just because it is always available at the nearby Walmart.
Pros: synthetic and meets JASO
One oil that seems to work from all the videos I've watched for cleaning varnish is the Valvoline Restore and Protect.
Pros: cleaning varnish
I use this on my Hyundai Elantra for the past 100k miles ... It's already at 200k and the engine still feels new ... I use Valvoline for everything including power steering ... Valvoline syn blend is a great oil option ...
Pros: engine still feels new
Vehicle:
Hyundai Elantra
Mileage: 200000 km
Valvoline protect and restore has more detergents than any other I believe to clean out thew gunk. I've been running it in my car for 3 oil changes now.
Pros: clean out the gunk
Vehicle:
Kia
i own a 2008 chevy colorado(2.9 4cil) and i used to buy all kind of expensive oils for it, nowadays i just use STP full synthetic 5w40 and change it twice a year

I've seen lots of videos showing the Valvoline restore and protect oil helping to clean engines. If you go that route I'd recommend replacing the oil filter after 500 miles then again at 2500 miles to keep the filters new for any gunk that gets freed up.
Pros: helps clean engines
Vehicle:
Kia
Mileage: 500 km
Change the oil at a minimum, and do it regularly. Use a quality synthetic high mileage oil and change it again in a couple thousand miles, then change on regular 5k mile intervals.
Pros: quality synthetic oil
Vehicle:
Mazda 6
I went to Valvoline once, oil pan emptied itself onto their floors the moment I started the engine. Joking aside I think it's perfectly fine to go to Valvoline, I go there often bringing my own oil and filter, that way I know it's the right oil and it's good quality stuff.
Pros: good quality stuff
Cons: oil pan emptied
I used Liqui Moly 10 40 for my 3vzfe 96 camry. The car started making a horrible ticking noise coming from the valve cover. Its at 225k miles. The engine runs good but noise is annoying.
Pros: engine runs good
Cons: horrible ticking noise, noise is annoying
Vehicle:
Toyota Camry
Mileage: 362100 km
