German Castrol oil thoughts.

The old "German Castrol" is still available in some places, it will be in the same bottle like you posted but will be 0w-30. It is available here local at both Autozone and Advance.
I run it exclusively in my car ever since I first tried it. The valvetrain noise went down noticeably. It is also often on sale for $29-32 with filter for 5 qts. Advance also often lets you pick up an extra qt for the sale price.
The "German Castrol" is on the thick side of a 30wt oil SO any engine is a little quieter using thick oil it may sound a bit quieter. NOTHING ELSE. Its not gonna last any longer or run any better. It just a waste of your resources.
I never heard a quiet LS engine...THERE is No such thing.
If you want to use a thicker oil just buy 10-40 cheap standard oil and WALLAA same placebo effect. The engine sounds different so it must be good now I feel fuzzy inside.

I'll tell you the secret to a long lasting LS engine, keep the oil overfilled and check it often. I always run 6 1/2 qts and check it every 500 miles. Most LS engines use a lot of oil and even one full throttle run with low oil will do damage.

You are right though, oil level and keeping it clean are what matters more.
Oil is all BS, buy the chgeapest major brand and keep it clean and full. There is NO other way. You can full your crankcase with what ever flavor of the week everyone is using but in the end clean and full wins.
Now if you are talking oil change intervals that's where certain oil are much better than others.
I use the synthetic and change it 5-7k miles depending on what the car has seen in those miles and how it looks. How it looks might not be the most scientific method but regardless, if it gets black and nasty looking sooner I change it sooner.
Hence the synthetic, I have enough old school mentality I wouldn't want to run standard oil that long in a performance application. My truck gets the same interval posted above with standard oil (whatever brand is on sale), but it also doesn't get beat on or revved even close to redline.
In all my LS engines I use the same without any oil related problems.
I'm not sure about the 0W-40.
I use it in everything I own and use it in every friend's car that I maintain.
I have about sixty quarts on hand-all from the sales at Pep Boys and Auto Zone.
Wix is an excellent filter-and if you can use a tall one, even better.
When I need an off the shelf oil filter, I reach for a Mobile1 Extended filter. My vehicles use Fleetguard filters. I'm pretty **** about my lubrication too
OP - I've tried at least 6 different brands, types, and weights of oil and Euro Formula Castrol clearly produced the quietest valvetrain. I also run the long Wix filter with no problems.
