Let's put this in perspective.

Board members represent .1% of general public who obsess with motor oil. I do it, because it's a change from politics or sports and so I can BS service writers.

OP represents .01% of super obsessors.

The rest of the public is split between people who look at their owners manuals and do more or less what they recommend, and people who never change their oil, run dry, buy SA oil at c-stores, etc.

I bought a 1988 Ford Festiva, way below book, that fell into that later group. First of five Hyun-Kia's that I've had good luck with-- or maybe it my first and last Mazda. Depends on how you define it.

IIRC the original owner put about 28000 on the car in one year. I'm sure the oil was never changed. Never did get it cleaned up, but I ran that car up until 110,000 miles with no incidents at which time the engine and clutch gave up the ghost. Replaced the engine and transmission and new clutch from a junk yard for about $600. Drove the car for another 10,000 miles and gave it to my teenage daughter who wrecked the new clutch. Gave it to a charity and it was still going two years later with probably close to 200k.

Engines are a lot more complex compared with thirty years ago, but oils are a lot better. We worry about things the general public could care less about.


Couldn't agree more.

Yup

When CATERHAM was discussing his mix, he was well aware that the resulting mix wasn't necessarily a 0w-XX. He had no intentions of relying on its cold weather performance in Canada.

Makes sense to me.

Finally im part of the 1% lol
 
*I just threw out the Caterham Blend as a possibility as both M1 0W20 and 0W40 synthetic oils have a strong following ... As for "what am I smoking " ? Are you aware that Hyundai has set aside over $800 million on replacement engines for the 2.4L Theta II engines (2014 - through at least 2017) ? - This is more than an "occasional problem" and points to a bad design of the Theta II engine (connecting rod bearings go and grenade the engine) . Also of interest to note that in the new Hyundai engines work order it states 5W30 oil and not 5W20 to be used in replacement engine fills at the dealer ... As for me , I use a 5W30 synthetic D1 / Gen 2 SN+ rated oil in my 2017 Sonata , keep it filled to "F" on the dipstick with no more than a 5K mile OCI and then hope I don't encounter the "Hyundai Theta II Death Knock" ... As for selling the Sonata GDI - the resale value has absolutely plummeted worse than the stock market of 2008 (or more recently from Oct. to Dec.) ... Lastly , why not at least explore or discuss the possible merits of a newer , better oil - blended or not ? ... As long as their is BITOG then such discussions can and have taken place - we can all choose not to participate - just say'n ...
 
Isn't Mobil1 0w40 loaded with calcium?....which should preclude it's use in LSPI prone vehicles...
 
Interesting. That got me thinking. The resell value of my '12 (via KBB/PrivatePartySell) is ~$13K and with my mods (to the right buyer), I'm likely in the $14K-$15K range.
Given my new engine I'm keeping her for a very long time so resell value is really not relevant to me at this point but it is worth determining.

As you may know, the deprecation of a car is worst in the first three years and then tends to flatten out. At 7 model years behind, I'm well in that flat range.

As to the OP, it is an interesting question about mixing oils and what benefit can be derived. But I'd rather leave that to the oil experts who design oil formulations for a living for their companies.

The fair question then is what are we trying to achieve from this mix? What by viscosity and by additive levels (that part is dicey given we really can't predict, much less test, the result of such mixtures) are we attempting to achieve that cannot be found in an off the shelf oil? I'm already running a readily available 5w-30 that has elevated HTHS, high magnesium, phosphorus levels at ILSAC limits, and more than sufficient TBN. One can easily find multigrade 30s with lower additive levels, higher additive levels, lower HTHS, lower TBN, in most combinations.
 
No oil is going to fix a design flaw if that's what you're hoping for, sorry. If I were affraid of the "Theta II knock of death" as you call it, I would cut my losses and get rid of the car. I couldn't bare owning something I had no confidence in.
As for the reason why 5w30 is used as the initial fill after an engine replacement or inspection? Both the 2.4 and 2.0T allow for that viscosity in the Owner's Manual. The 2.0T does not allow 5w20. Using one viscosity keeps the process consistent and fail safe. If we follow your extrapolation, the 2018 and forward Owners Manuals would recommend 5w30 to mitigate further failures. Good luck trying to find a solution and let's hope your Sonata is one "of the few" that remains reliable.

^ This. I also used to overthink the problem and tried to find some perfect oil, but then realized it's gonna be easier just to find something that works properly for my engine and stick to it.
For me it's going to be Magnatec 5w30 d1G2 from the next OCI (right now subscribe and save on Amazon ~$10 for a first delivery and $18 for future ones), life is too short to worry about the oil this much

*Yes to your question - next , what 5W30 are you running currently ?

If the Sonata is still under warranty, you can try Mobil1 High Mileage 10W-30.
It still an API SN Plus oil as well ACEA A3/B3, the HTHS is 3.5 and the viscosity is recommended by Hyundai. Or try what Garak does...a dual spec HDEO that will meet at least the SN requirements.

No, he stated many many times, that
* of COURSE two 0Ws ALWAYS creates a 0W
* ASTM D6922 mandated that the above was true
* That Appendix E, the base oil interchange guidelines validated mixing two fully formulated oils

He probably got sick of being called out on his nonsense...but his fanbois all thought he was being picked on.

He did great work with is oil pressure viscometry for HTHS...but made up a LOT of stuff that he didn't like being called on.

(That's a pretty common thing on BITOG).
 
e.g
https://bobistheoilguy.com/forums/ubbthreads.php/topics/3530483/Re:_Mixing_PP+M1 ... note the "pile on", correcting incorrect statements and the similar behaviors that he displays to another current (and regularly incorrect) poster ???

Oh brother

, this so sounds like high school (but at least there there would be no talk of PCMOs

)

I really miss reading threads in which CATERHAM contributed to...BITOG is definitely lesser w/o his input.
