For the money the best zinc content is valvoline vr1 CONVENTIONAL (not synthetic). It comes in a few flavors.
Pros: best zinc content

I run 5w-40 in everything. Mazda Skyactiv, Toyota 3UR, Honda J35. They all like it and run quiet.
Pros: run quiet
Vehicle:
Mazda
My '15 Forester will burn a quart of oil every 1000 miles if I run 0w20.
I switched to 5w30 and it's all good for 5000 miles
Pros: good for 5000 miles
Cons: burn a quart of oil
Vehicle:
Subaru Forester
Mileage: 5000 km
Motul Xclean EFE 5w30, Xclean gen2 5w40
That said, I use Motul 0W20 in the winter and 5W30 in the summer.
Pros: using Motul oil
Vehicle:
Subaru
My engine is happy with Pennzoil Platinum. No leaks and minimal oil consumption.
Pros: no leaks, minimal consumption
Avoid Castrol. Use Mobil1 or LiquiMolly.
I'm using 5w40 and never had issues overheating in summer but im not doing half hour pulls. No oil consuption also. With 5w30 when driving hard it was eating a lot of oil.
Pros: no overheating, no oil consumption
Cons: avoid Castrol
I use castrol 5w-40 Euro on my 2006 Revup. Good oil pressure on hot SoCal days and burns less oil.
Pros: good oil pressure, less oil burn
Vehicle:
Nissan
Random guy who works on these cars here, change it at 5-6k regularly. Ignore the casuals here who don’t work on these cars, and especially Ignore the factory recommended interval. Your engine will last much longer, you’ll reduce wear on the timing chain, turbo, as well as other components. You’ll also reduce the chance of your piston rings getting glued together with carbon creating excessive oil consumption. Just change it. I recommend liquimoly oil.
Pros: reduce wear, engine lasts longer
Cons: excessive oil consumption
Mileage: 6000 km
Rotella T-Syn is a great oil but for our turbos...i wouldn't recommend it since if any oil gets burnt or makes it way through the rings...the higher amount of ZDDP (zinc) found in the Shell Rotella Synthetic oil will be harmful to your catalytic converter which may cause a failure.
Pros: great oil
Cons: harmful to catalytic converter
