Anyone doing a 'frankenbatch' of oil?

hey all, i noticed some people on here really like several oils or some are stuck to a certain one in particular

i have read about some people mixing but i assumed on a forum full of enthusiasts, more people would be mixing and making a frankenbatch

i don't necessarily see a harm in this but wondering what yall think about it and what brews you all are running? maybe we can make some recipes for ultra cleaning, ultra long OCI, ultra stabile

in the future when i get the time, i'm thinking of running 1/2 PUP + 1/2 Castrol Edge EP for fun

or maybe even mixing VRP with some other high detergency oil

**truth be told, i know we can't formulate a better product, this is just for fun / being an enthusiast**

ty!
Why do people “mix” different oils for? No need to mix different brands, because at the end of the day, using a good oil that has api or acea or whatever spec you like, and changing it on time is what matters the most.

I’m an engine/car/oil enthusiast too, (that’s why I’m on Bitog), but I never thought of mixing different oils. Just use the one you believe is the best for your engine.

Using any oil that has the approvals your vehicle is fine. Mixing different oil is a gamble. You’ll most likely do more harm than good in the long run.

Being an enthusiast is great, but I don’t like people that do chintzy stuff to their cars. Mixing different oils is like putting a ford badge on a chevy, and using ford motorcraft parts on a… Porsche somehow… things that make me say, “just…. why? What’s the point?” but hey if it works, then I guess it’s kinda cool 😂

I think people don't like having a bunch of half quart lying around.
 
Many valid reasons not to blend - but if you do then one I might try : M1 0W40 FS (50%) + M1 10W30 EP (50%) . A potentially good blend for Hyundai specific challenged engines (brought up by another member here) .
 
Any oil left from changing oil in my truck, boat, and 68 Firebird is collected and serves as oil for my lawn equipment. Not for a “superior blend” but it won’t go to waste. A lawn mower, tractor, or generator doesn’t mind 5w30, 10w30, or 10w40….
 
I've read threads here where someone will throw in a quart of HPL cleaner oil into the crankcase to supplement whatever regular oil they are using, with the idea to supplement sludge clean out.

Personally, I've mixed to clean out partial bottles somewhat regularly, and my car seems just fine with that. I've also mixed 0W-20 and 5W-30 together, half and half, to use up the thicker oil. First time with the full 5W-30, the engine felt sluggish when cold, and I imagined that my short trip driving wasn't a good fit for that oil, so I started mixing to use up stock.
 
This post is unfortunately premised on the idea that mixing fully formulated products could somehow result in a product that's superior to any of its individual constituents. The odds of that being the case are so remote that it borders on the impossible. It's the "infinite number of monkeys on an infinite number of typewriters could produce literature superior to Shakespeare" theory manifest.
My money is on the makak. Who's in??

I've done the odd mix of 6qts one brand, 1qt another. But never to create a superior product. My mix usually follows a " D.A.M.N! Thought I had another quart."
 
I mix various clearance oils, no problem.

I only care about proper oil level.

***Info added****
I found some PYB, Havoline HM and Havoline Syn oil from like 12 years ago.
I will mix this up for a Mazda oil change.

Will take photo tomorrow of this antique oil.

Here are the photos.
I got approx 7 quarts of each oil.
Did the oil change and 2.5L engine runs just fine.

Havoline is approx 20 years old. LOL. ;)

Sure. Just like only Colonel Sanders knows that secret blend of 11 herbs and spices.
It seems you may have a functional misunderstanding. Taking multiple completed products, whether oil or aftermarket additives, and dumping them into a shared sump can never be considered “blending” similar to how an oil manufacturer does it. You’re performing a “mixing” operation only, and where your misunderstanding lies.

Maybe have another look at @OVERKILL ’s informative posts on the topic.

If you could mix oil A & oil B in your back yard and come up with better performance results than either oil by itself, don’t you think somebody would already be marketing that fabulous oil C by now?
 
no benefit and i give a big (n) on it. now if i was short a 1/2-1 Qt to complete an oil change, thats a different story but just to franken-brew no. and of course only if its the same wt and rating.
 
A recurring entry I see here is how to handle partial bottles. My vehicle refill amount is about 4-1/3 quarts, which leaves 2/3s in the gallon bottle.

This is where having a Fumoto drain valve comes in handy. At about 1000 miles before my next planned OC, I drain about 2/3s and refill.

A spinoff topic could be, “Tell Us What You Do With Your Leftover Oil?”
 
I mix but like to keep the oils in the same Family --- Pennzoil with Pennzoil HM, Quaker State with QSHM, Mobil One with Mobil One HM,,, Considering the Tundra takes almost 8 quarts with a new filter change. It just works out that way.
 
I do the occasional "Witches Brew" of various orphaned bottles and jugs of various brands and grades of oil. Never had an issue or concern with it.

I knew of a shop truck at a local independent that all it got was the collected drippings from all the oil changes they did with many customer brought in oils.
