Blending Kirkland and Supertech oils???

I don't like to mix brands because different brands have different additive packages, which may or may not be fully compatible. If they're not fully compatible, increased wear or sludge might result, but it wouldn't be enough for you to notice if you only ran it that way for less than 10K miles. Even if you ran Frankenoil for more than 10K you might never have an issue that you'd notice.

So can you mix oil brands? Yes, but it's not ideal.

Should you mix brands? Normally no, but if you're low on oil then adding another brand is better than being low on oil. A Frankenoil mixture is much better than being low on oil.

P.S. - If both oils are made by Warren, then it's the same oil. So you're not mixing brands.

And always get a Hotdog at Costco.
I think that is the most relevant advice on this thread. I get a Costco hotdog everytime I am in there. When I lived closer to one I would get a hotdog for lunch. As I tried to completely 100% offset the cost of my 130 a year membership by buying hotdogs. Which means I have to get minimum of 43 hotdog combos a year. As they loose about 3 dollars per combo. Long story short I try my best to have Costco make $0 off of me because I am that cheap hahaha.

Are hot dogs free at costco (with membership, of course)?
 
No they are $1.50 for the hotdog and a drink and have been since day one. Adjusted for inflation they should be about $4.50. Costco looses money on everyone they sell. So if you buy enough of them it will completely offset the cost of your membership.
Things are changing now but you used to be able to go into the food court without a membership and get a hot dog.
 
There are people on this site that know more than you , and there are those that have a different opinion than you . Learn to spot the difference in the two . Mix , blend , comingle , or however you want to call it . Your car will be just fine . And that's not opinion . I've done it many times .

I thought Circle K had the best deal ($3 for a weiner, chips, and large soda), but $1.50 is d@mn good!
