YouTube video comparing M1 & Kirkland. Black stone run through.

[Snowcrash]

Came across this guys channel and video on YouTube. For me it was one of the best and simplest I have come across. Wondering what you experts think? Based on his video I am going to try Kirkland for a few cycles on my 2014 Forester with 144K.

Another YouTube “analysis” that naively attempts to determine comparative oil quality through a $30 spectrographic analysis. Plus the overall problem that Blackstone is apparently incapable of making a proper flash point measurement. The guy really has no idea how much fuel is or is not in those samples.

No thanks this time either. Yes the Kirkland is a serviceable oil. Other existing threads on similar comparisons between Mobil 1 and Costco oil.

Blah another youtuber with a UOA.

sigh.....nothing wrong with Kirkland (Supertech.) This video, however, is useless......@kschachn hits it on the head.

 

[Snowcrash]

alright thanks.

To his credit he actually did a few 10k runs and isn’t just comparing unused oil and adding up ppm of additives to conclude one is better.

Seeing consistent wear metals over three 10k intervals is useful information, boron isn’t depleted (it’d be nice to know what the starting value was), TBN isn’t bad. If he’d sent the samples to a lab that did oxidation testing and saw similar results between Mobil and Kirkland I’d say for his car and his driving it’s perfectly fine to use Kirkland over Mobil.

Yep, probably way more fuel in that sample than 1.3% because of how Blackstone "measures" (extrapolates) it. But we've beaten BS with the ugly stick for years and you get what you pay for. The gist is what the OP is doing with his oil choice and basing it on a YT commentary with a few UOAs throw in for validtiy. Whatever ya wanna do, but don't expect many of us to jump up and down and praise the "superiority" of the Kirkland oil over Mobil 1 based on that. If you get it cheaper and easier than M1, and don't beat up your oil, give it a shot. Warren can blend up a decent product and if it saves you some beer money, then bonus.

We know better than many YouTubers that Kirkland oil is decent, while Mobil 1 is about as good as it gets. These tests don't really mean much, and that "fancy paperwork" he's holding is essentially meaningless too.

A meaningful comparison would involve running both oils for half a million miles in identical engines, then tearing down the engines for inspection - similar to what we saw in Valvoline's half a million-mile video.

Personally, I believe that after half a million miles, if the engines were torn down, there would be noticeable differences between Kirkland and Mobil 1.

I don’t know much, but these two oils mostly carry the same approvals, and when you start examining the requirements there isn’t a whole lot of leeway for them to be much different in a UOA. To carry all the latest API, ILSAC, and Dexos approvals they’re both going to be almost the same especially over only a few OCI’s. Short of a novel additive like in VRP the performance should be equivalent and that’s pretty much what his UOA’s indicate. If M1 has something novel that would justify a higher price over Kirkland (triple action?) they don’t seem to be marketing it as well as Valvoline. This from a M1 AFE user myself.

The only thing noticeable after looking at a lot of M1 AFE VOA and UOA are the relatively lower add pack numbers of AFE, there is speculation that is uses other additives not normally identified in a UOA/VOA to compensate, but I haven’t seen proof. In this 4 year old thread thread admin Molekule says they’re using other anti-wear additives in M1.

I do wish we could see more testing like the Valvoline 400k teardown! It is good marketing by them, and as much as I would prefer to send money to Houston and not Riyadh (actually Dhaharan, I’ve been there), I just bought a few gallons of VRP.

I think at 10K OCI for half a million miles, probably.

@7,500K OCI for half a million miles maybe? Not so sure on that.

@5K OCI for half a million miles, probably not much difference.

And, we still don't know the actual fuel dilution here. That plays a big part too.

The odds of any single car lasting 500,000 miles is so remote anyway, it's almost pointless to speculate. Rust and collisions destroy huge numbers of cars every year. There's about 6 million total collisions per year in the USA alone. On paper, I think the M1 is the better product, but the Kirkland will almost certainly keep the car alive long enough to get totaled in a collision or sold for scrap due to rust.

Blah another youtuber with a UOA.

I mean we have an entire sub-forum here full of them...another BITOGer with a UOA the same thing?

I think it’s great to have another data point. Time and time again Kirkland/supertech/warren/etc has proven to be a great oil

Costco does not have a history of putting the Kirkland name on crap products.

Was that you?

Yes, typically KS has great quality products but I have experienced a number of blunders where some KS products were
