Mix them up, no problem. I recently did a 6500-mile run with 2 quarts Mobil 1 10w30, 1 quart O'Reilly house brand synthetic 5w30, 1 quart Napa synthetic 0w20 and 1 quart MM oil. No problems, ran great the whole time.

No issue whats so ever!

Our Odyssey has 5qts of 5w30 and .7qt of 0w20.

Now there's a problem you're low on diversity!

All motor oils, especially if they are SN or SP, are a heck of a lot more similar to each other than the marketers would have you believe. Mix away!

As long as you don't include a bottle of unused olive oil from your kitchen in that mix, you should be fine.

Dang! I thought that was the secret... Virgin Olive Oyl.

 

[aquariuscsm]

Frankenbrew in!

If you don't add 8oz of Magnatec for smoothness, Arco will be disappointed.

Especially in the last couple of years. It used to be that a brand like Valvoline would use a different additive pack than the others (more sodium based) but now they too have fallen in line with everyone else. I think engine design (turbos, direct injection, lighter weight oils, CAFE regulations) has changed the game.

I love using up straggler quarts and even partial/open bottles. It doesn’t bother me a single bit to put in a variety of brands & grades as long as they’re acceptable in my engines.
