It's the Chicken Little effect.
There are those that run around claim the "sky is falling" and there are those that say "well it hasn't hit me yet".
I'm in the second camp.
All oil formulators say their oil is compatable with every other PCMO out there. No evidence to the contrary has been presented.
Consiquently claiming otherwise is simply fear mongering.

I've been wondering the same: mixing to get rid of odd bottles? For those who say "use it as top-up, or in small engines"....my vehicles never use any oil. Thus, I never top-up. Small engine needs 10w30. My oil is 5w20. I don't think my Chonda OHV will like that. I have mixed before, and never noticed any issues.
i have a 5 quart jug that gets all my 1/2 quart left-overs. probably 5 different brands and weights in there currently. I use it as my pre winter storage oil change fill for my motorcycle and push mower. When the spring roles around, I ride the motorcycle for 50+ miles and mow the lawn, then change both to a single brand
My opinion is it would be just fine.
I have done it in the past (generally with the same brand dino+syn). I have seen many others do it with no ill effects.
My dad for example used to buy clearance oil .79 cents or .69 stuff and mix it with his "better" stuff that was .99 cents. This was years ago of course. He drove that car for 10 years doing that at least 5 years.
I think you will be fine. In the end it will drain out.

Running a mix of Quaker state, Mobil Clean 5000 and Pennzoil in our beater Volkswagen; some 10w40, some 5w30.
I take orphan half used quarts of oil and dump them into a 5qt jug. The end result gets dumped into the beater...also used for topoffs.

Don't over think it, just run it. You're not changing the oil on an artificial heart.

Pretty simple:
API specs include compatibility tests.
used oil analysis from mixed bag oils come out fine as well.

Mmmm.....obesity
well think about it, that would make one tasty egg. So using this example, it would make the best oil ever.

Just look at it as "the best of" ..or "greatest hits" of your oil usage history ..all wrapped into one sump.

Read the patent application for the low phos add packs and then call it fear mongering. Ive posted the links before. Do your own research. Dont ask those whom are unqualified to give you an answer - just because thay are members of an oil board - that just builds the "Idiocracy".
from patent 7183241
As is known in the art, additives are used in lubricants to perform numerous functions. For example, some are antioxidants, some are friction modifiers; and some are extreme pressure agents. Indeed some additives perform more than one function. Also as is known in the art, additives will lose their effectiveness if they are improperly combined. Therefore, extreme care must be exercised in combining various additives to assure both compatibility and effectiveness. For example, some frictionmodifiers affect metal surfaces differently than antiwear agents do. When both are present, friction-reducing and antiwear additives may compete for the surface of the metal parts which are subject to lubrication. This competition can produce alubricant that is less effective than is suggested by the individual properties of the additive components.
Accordingly, the components of a gas engine lubricant need to be selected to meet the specified ash level and to provide, among other functions, a high level of oxidation and nitration resistance. Whether selected components and their amountscan be balanced to meet desired specification is not a priori predictable.

why do the makers state their oils are compatible then?
