Is it ok to mix motor oil from two different brands?

I have 5 quarts of Motor craft 5w20 Synthetic Blend and 2 quarts of Valvoline 5w20 Synthetic Blend. Ok to mix at the next oil change?

I feel like its fine to top off with different oil if its low, but I wouldn't want to make a habit out of mixing oils at oil changes. Can you do one this time, and the other the next? Using both up separately

Yeah. It's fine. "Don't mix oils" is a thing of the past.

The price for MC in my area has gone up a lot. Now it is around $9 bucks a quart and $35 for a 1.25 gallons. Sucks.

I bought two Valvoline 1.25 gallon jugs for $34 shipped.

Truck takes 7 qts per change and I have 5 qts of MC and 10 qts of Val.

I was going to mix this one time and the next be pure Val. Hopefully the MC prices go down by then to switch back.

Motor craft oil is still the same $18 for 5 qts. here in Michigan. Wonder why its so expensive in az.

Walmart shows $17.97 but the shelf has been empty for a while now. I have to look online and that is where I am finding the prices of $35 for 5 qts.

35 bucks or say 5000 for a motor? Don't be cheap on certain things.

Let's stick to the topic of mixing oils.

Mixing the oils is fine. Some people mix them on purpose to to get a certain mix since different oils have different additives. So mix at will, it'll be fine.
