Quaker State-Pennzoil frankenblend?

[KansasBuickFan]

Would anyone hesitate to do a 50-50 Frankenblend of Quaker State 5w30 full synthetic and Pennzoil Platinum 5w30?

 

[wemay]

From leftovers? No.

But I wouldn't go out of my way to do so.

 

[cheesepuffs2]

Nope. It'll be absolutely fine. Run with confidence.

Why not?

Nope....

They are both from the same company. No worries.

Even if they are not what is the big deal in mixing????

I'd use it.

I love a good Frankenbrew. Running M1 HM 5w30 and 10w30 in the Tundra right now. Never ran so good!

Mix these colors together and you get something like this,

which is called Chartreuse

I mixed 3 quarts PP 5w30 with 1 quart QS “all mileage” 10w40 on my last oil change and the engine runs great. So I’d have no issues mixing PP with QSFS.

Sometimes you're very funny. I don't think I've mentioned that before ... anyway, you frequently provide a big chuckle!

A mix will work but it may not be optimal. I wouldn’t make a habit of it.

Shoot, I had leftover qts from 0w20, 5w20, 5w40 and 20w50 that ran well in my old truck. All different brands. 50/50 is fine

You are good to go. Reduce that clutter in your garage and try to be a minimalist. I was previously an oil hoarder and dropped the habit because there were no good deals to be found after Covid. Darn it anyway.

For the 828th time.

As long as the mixed oils have an API license or have otherwise passed ASTM D6922 then they are miscible.

Which doesn’t mean they still retain any license, certification or approval the individual oils may have originally held. Nor necessarily meet the requirements for any particular winter rating.

But it does mean there won't be an issue nor harm your engine.

Isn't that 829?

My truck 8.8 qts, my Explorer 5.2 qts, my Focus 4.5 qts, wife’s EcoSport 1.1 gal, son’s Bronco 5.5 qts. So normally they all get a little Frankenbrew for the partial qt. All have done well.

Mix I'm currently running:
1 qt ea QSGB 10w30, Havoline 5w30, PYB 5w30
2 qt SuperTech synth 5w30

The QSGB was a remnant from my 1988 Accord, which I sold in 2008.

Because?
