No, it means if I wanted to deal with piston rings through the filler cap hole … I’d do it like BrocL did …Does this mean we like Lucas oil stabilizer now?

Interesting it would mention gelling. While I have dumped most of my "scraps" into my "lawn mower" jug and used this Frankenoil in my small engines for years, I do look for anything strange. Before using it I always give it a good shake. And I pour it into a clear measuring cup before it goes into the engine. I've never noticed anything unusual...no weird coloring, no clumping, no streaks or gelling. And this mixture has about everything in it...conventional, synthetic, various brands and just about any weight under 50.
When I change the oil in my small engines I always examine it. I never seen anything unusual in there as well....though I'm no expert.
Would I run this type of Frankenoil in one of my vehicles? No. In a lawn mower....especially one as old as mine? Sure.
As I mentioned earlier....I do have 2 quarts of Valvoline synthetic 0/20 and 2 quarts of Valvoline synthetic 5/30 that I accumulated over the last few months that I intend to use in my wife's Corolla. Same brand, both synthetic, both in the same family within the same brand...just different weights. I feel pretty comfortable about using it. What are your thoughts?
I did read the thread and I also actually UNDERSTOOD it too and its not what's in question or even close.If you read the thread, an oil formulator recommended mixing two different oils to help clean piston rings. Which is of benefit to the engine, which is the question you asked.
Not directed at your claims or you but that's the point. There is no reliable verifiable proof that any of this mixing did anything a fresh oil change wouldn't accomplish with all the apothecary stuff.As far as true mixing goes, It was a hit or miss affair over the decades.
Thoughts on the Valvoline synthetic 0/20 and 5/30 being used in a vehicle? Being the same brand and type of oil...I never gave it a 2nd thought for using it in my wife's Corolla spec'd for 0/20 until I started reading this thread.The most likely (and the probability is extremely low) interaction is something happening to the cold temperature characteristics, which is why the pour point is tested as part of the standard, because that's where negative interactions have happened in the past. With a lawnmower, that isn't going to be a concern, and you definitely don't need to worry about it meeting LL-01 or A40, so it's a pretty good application to use up spare product all things considered.
Far less likely to do strange things when it is the same brand of oil.Thoughts on the Valvoline synthetic 0/20 and 5/30 being used in a vehicle?

No intentions other than using perfectly good oil. I had accumulated 2 quarts of the 0/20 and 2 of 5/30 from OCs on various friends vehicles.Far less likely to do strange things when it is the same brand of oil.
Why are you mixing them though? What's the intention?
Will do. Thanks for your inputIt's probably pretty safe, both being Valvoline, if you aren't going to see -30C it is extremely low risk, so you might as well use it up.
+10 BITOG points for using synergy in a replyThey are mixed with a group of reference oils to ensure they don't split or do anything unexpected. They are in no way tested to confirm they retain all of the same performance characteristics they had when initially tested.
The biggest risk from mixing is a potential significant impact on the Winter rating. That's the most likely characteristic to be affected.
In the past, some oils have used significantly different additive package chemistries, for example, Valvoline used sodium, while nobody else did. Currently, Ravenol uses Tungsten while other manufacturers use moly. I'm sure you can recall Castrol and Kendall using Titanium. Some will use tri-nuclear moly (Mobil/Shell) while others may use more traditional forms of moly that require a higher treatment rate to achieve the same effect. They may also use different types of VII polymers.
While the potential for significantly negative synergies is quite low, upsetting the carefully selected balance of additives, particularly when mixing oils from different vendors that use different chemistries is not going to result in an improvement in performance, you are essentially guaranteed to have made something worse but it's unlikely that you'd ever notice it or that it would be significant.
Edit: I see @kschachn beat me to this bit, so I'm essentially reiterating, lol.
I’d probably just pour the jug inI'm running a mix of leftover oils right now. Car only takes 4.25L and oil comes in 5L bottles, so every sixth oil change gets whatever is left over, assuming no need to top off between.
Please calm down and read the link again, because it is not a blender making a custom oil from scratch, it is a blender answering the question of mixing two already formulated oils purchased off the shelf, Nulon 25W60 with Edge 10W30. He liked the idea and gave his reason, and also gave me his preferred ratio.I did read the thread and I also actually UNDERSTOOD it too and its not what's in question or even close.
Putting the claims aside ( that's a different subjecnt) this is a blender talking about base stocks to make a custom oil from scratch ( which is what they do with a custom ad pack)
That's NOT the same as putting PUP and QS in magic bullet with a dash of #2 grease to make Frankenbrew.
So, you are saying, "mixing yields unpredictable results", and at the same time also saying "the brew is no better than the individual oils"Now, the appearance that most SP/GF6 lubricants share additive technology may make mixing more desirable/palatable for many, but we should never consider the brew is better performing than the highest quality oil used in the mixture.
The multiple jugs were on my garage shelf, and not empty.How did you wind up with the extra L ?
