Default Mixing brands of oil and weights

Is it a big deal to mix brands of oil and weights?

I ask because I have quite a few partial quarts of oil that I would like to get rid of. It is all Full Synthetic, and a mix of 75% Mobil 1 and 25% Valvoline. It is all 5W-30 except for 1.5 quarts of 5W-0. I have 2 oil changes to do in the Subaru and the Honda I have enough quarts to do both oil changes, but if the 1.5 qts of 0 says it offers the same protection as 5-30, can I use that up?

Odd situation but I'm getting sick of all these partial quarts of oil. With every vehicle using somewhere between 4 and 5 quarts of oil, I'm always left with a little bit and it's just pissing me off this evening.


PS: If it matters, I have almost 90,000 miles on the car. 2.5 auto.

1.5 quarts of what? 5w0 does not exist. 5w20, 0w20? And yes, you can make a blend with little effect.
2003 Outback: "Kaylee". 143,000 and counting.
Basics: Quaker State Ultimate Durability 5W30, PureOne oil filter, Fram air filter, Valvoline Maxlife Dex/Merc ATF, Mobil 1 75W90, Michelin Primacy MXV4.
Mods: Fumoto oil drain valve, Phillips VisionPlus low beams, HIR1 Phillips high beam upgrade, Nokya Hyper Yellow fog lights.

Also: More rust and parking lot scars than I care to think about.

No problem mixing 0w-30 and 5w-30 from different manufacturers. One reason for having API Specs is that the products are compatible. Fleets that select lowest bidder lube contracts change oil brands regularly.
