Why are you concerned about viscosity and not the over all package? A really thick oil with no certifications or weak additive package will not protect as well as a fully formulated oil with builder approvals and certifications.
The Walmart Supertech 15w40 is fine as well as any name brand HDEO like Rotella.

That concerns me also. Just all of the oils walmart and tsc sell are all national brand names. Just looking for the thickest oil as I have a truck that leaks it alot and the little bit I use it dont justify paying to have new seals.

Try an oil with seal conditioners in it.

"The thickest 15W-40" is like "the slowest fastball"
What is wrong with 20w-50?

Use ATP Re-Seal in the cheapest 15W40 you can find-it slowed my F-450's rear main leak down to a trickle (from a puddle).

+1
Or a high milage 10/15w40. Heck even Maxlife 20w50 since it's sunmer there, 20w50 Maxlife has completely stopped every seepage around my engine

Yes the ATP 205 re seal has worked wonders on many vehicles, just read the reviews.
Also Liqui Moly 2020 oil saver does a very similar thing.

You want thick, just dump in some of that Lucas junk or go to a 15w50.
Or just add a couple liters of three dollar SAE 50 HDMO at OCI time, or for a top-up.
I would stick with the same brand, and only as a 3-season solution.
