Blending Kirkland and Supertech oils???

[huntsonora]

Both are Warren. I would like to buy the 5gt jugs at Costco and then buy individual quarts from Walmart to keep us easy. Anybody see an issue with this? Any idea how close these oils are?

No issue with mixing any brands/types/grades of oil ever.

I see no issue. I'd assume these basic oils are dead even in composition.

 

[OVERKILL]

You would be "mixing" but yeah, they are probably the same oil.

Both SuperLand and KirkTech can do 5k …

I have to ask what makes you thing there would be a problem?

What @OVERKILL wrote.
If there are any differences between them, it probably isn't more than the lot-to-lot differences in either one.
Warren most likely offered the same product to three retailers to label as their individual store brands.
Cost wise, for the producer and retailers, it would make the most sense to hit the price point for a basically generic product.

Same oil, the only difference is the brand and the price

Not sure if that even qualifies as a Frankenbrew. And I love a good Frankenbrew.
My beloved Tundra is running 5w30 + 10w30 M1 as we speak... The horror!

Mix away my friend.

It's totaled.

Assuming they don’t spontaneously combust when they come in contact with each other, should be fine.

You have to make sure you are wearing your Birkenstocks when shopping for the Kirkland oil, and your pajamas when buying the Supertech.

Oh no don’t you dear do that are you trying to blow up your engine ?

Just verifying before I do it. Maintenance is important to me and I wanted to ask people that knew more than I do before I did it. That’s what this forum is for isn’t it?

Why not just buy a few 5qts jugs of Kirk and be done with? It is usually cheaper in the longer run than buying single quarts. Seems like you could save some money and some worry that way. You are going to use the remainder eventually anyways right?

It will be just fine.
